01 Oct 201415 Years of CUPS...

CUPS 1.0 was released [https://web.archive.org/web/20000126074742/http://cups.org/news.html#01OCT1999 15 years ago today], and a lot has changed. That first release supported IPP/1.0, PostScript and CUPS Raster drivers, and network, parallel, serial, and SCSI printers. It even included a copy of GNU Ghostscript to support the PostScript workflow that was standard in 1999.

IPP/2.1, PDF workflow, Bonjour, USB printer support, persistent job history, multiple-file jobs, authentication, encryption, policies, quotas, per-printer sharing controls, and the web interface all came later and have been refined over the last 15 years. Even the CUPS.org web site has changed dramatically - browse through the years in the Wayback Machine link above.

Today our focus on printing is much different than in 1999. Wireless networking and mobile computing are everywhere. We no longer want printer drivers, but expect printers that support standard protocols and formats with fantastic output quality that we could only dream of 15 years ago. And our printing is more focused and personal.

Thank you everyone for helping make CUPS the success it is today, and for helping us to continue to make it better in the future!

Happy Printing!

– Mike Sweet, creator of CUPS

30 Jul 2014CUPS 2.0b1

CUPS 2.0b1 is the first beta release of CUPS 2.0. The focus of this major release is mainly on performance and security improvements.

The CUPS library now provides a complete set of APIs for implementing HTTP and IPP services, and the scheduler uses those APIs to provide a modest code size reduction and corresponding improvement in performance. The scheduler is now also launched on demand on Linux, so for most users cupsd will only be running if something is being printed.

SSL/TLS support has been largely re-written to support certificate validation and policy enforcement, and on the server side we can now use different certificates depending on the hostname used. OpenSSL support has been dropped for a number of technical and security reasons.

IPP Everywhere support has been expanded to support long-edge feed printers and automatic retries using PWG Raster as needed. Finally, the ipptool utility has been updated with features needed to support IPP Everywhere printer self-certification.

We hope to release CUPS 2.0 in the coming months. Please let us know if you run into any issues with this beta release via the Bugs page at:

https://www.cups.org/str.php

17 Dec 2013Remaining CUPS.org Services are Back Online!

After a very long absence, I am pleased to announce that the CUPS.org bug database is back! CUPS.org login accounts, along with all bug reports, have been restored from the old web site.

The CUPS forums are now delivered using GNU mailman exclusively (no more NNTP access), with the cups.bugs, cups.ddk, and cups.development newsgroups merged into a single cups-devel mailing list and cups.announce and cups.general merged into the cups mailing list. Both of the merged lists were populated with an archive of the old NNTP server messages and can be searched. You can subscribe to the new lists on the Lists page.

Sadly, a few things will not be coming back to CUPS.org, including the PPD (driver) database and the live Subversion repository. However, we are planning on providing a read-only GIT mirror of the CUPS Subversion repository - more on that once we have it working reliably for all active branches.

If you run into problems, please send email to the webmaster or file a bug.

Thank you for your patience, and welcome to the new CUPS.org!

05 Jun 2006Debugging SNMP Printer Detection Problems

The new SNMP network printer detection functionality in CUPS 1.2 sometimes exposes problems in vendor SNMP or IPP implementations. If you are experiencing long delays in loading the CUPS web interface administration page, or if you don’t see your printer listed, the following instructions will help you to diagnose those problems and/or provide important feedback to the CUPS developers so that we can correct problems and improve the SNMP backend in future releases.

Quick Fixes

If you don’t use “public” as your community name, create a text file called /etc/cups/snmp.conf and put the following line in it:

Community your community name

If you have more than one community name, list them all on separate lines.

If you don’t support SNMP v1 on your network, you are currently “out of luck”. That said, we will be adding v2, v2c, and v3 support in future CUPS releases once we have a handle on the actual requirements people have for such things. Please file or update an SNMP enhancement request (http://www.cups.org/str.php) with specific requirements you have - what you need supported, why you need it supported, and how you would like to see the functionality provided/exposed - so that we can do it “right” the first time.

Basic Debugging

The SNMP backend supports a debugging mode that is activated by running it from a shell prompt. If you are using Bash (/bin/bash), Bourne shell (/bin/sh), Korn shell (/bin/ksh), or Z shell (/bin/zsh), you can run the following command to get a verbose log of the SNMP backend:

CUPS_DEBUG_LEVEL=2 /usr/lib/cups/backend/snmp 2>&1 | tee snmp.log

For C shell (/bin/csh) and TCsh (/bin/tcsh), use the following command instead:

(setenv CUPS_DEBUG_LEVEL 2; /usr/lib/cups/backend/snmp) |& tee snmp.log

On MacOS X you’ll find the SNMP backend in /usr/libexec/cups/backend instead:

Dissecting the Output

The first two lines are just informational and let you know that the default community name and address are being used. Lines 3-15 contain the initial SNMP query for the device type OID (.1.3.6.1.2.1.25.3.2.1.2.1) from the Host MIB.

Lines 16-31 show the response we got from an HP LaserJet 4000 network printer. At this point we discover that it is a printer device and then send another SNMP query (lines 32-43) for the device description OID (.1.3.6.1.2.1.25.3.2.1.3.1) from the Host MIB as well.

Lines 44-58 show the response to the device description query, which tells us that this is an HP LaserJet 4000 Series printer.

On line 59 we start our active connection probe and discover that this print server supports the AppSocket (JetDirect) protocol on port 9100.

Finally, line 63 shows the device information line for the print server that is sent to CUPS.

Reporting Problems

If you don’t see your printer listed, or the wrong information is listed, then you need to gather more information on the printer. The easiest way to do this is to run the snmpwalk command:

snmpwalk -Cc -v 1 -c public ip-address | tee snmpwalk.log

where “ip-address” is the IP address of the printer or print server. You should see a lot of values stream by - the ones you want to see are:

HOST-RESOURCES-MIB::hrDeviceType.1 = OID: HOST-RESOURCES-TYPES::hrDevicePrinter
HOST-RESOURCES-MIB::hrDeviceDescr.1 = STRING: HP LaserJet 4000 Series

The hrDeviceType line should show hrDevicePrinter; if not, then your printer or print server doesn’t identify itself as a printer. The hrDeviceDescr line should provide a human-readable string for the make and model of the printer, although in some cases you’ll just see something less useful like “Axis OfficeBASIC Parallel Print Server”.

Once you have collected the snmpwalk output, you should go to the CUPS Bugs & Features page (http://www.cups.org/str.php) to submit a feature request to support your printer or print server. Be sure to attach those two log files you created - they will help us to identify the SNMP values we need to look for.

CUPS 1.2.1 is now available for download from the CUPS web site at:

    http://www.cups.org/software.html

CUPS 1.2.1 fixes several build, platform, and printing bugs. Changes include:


08 May 2006Common UNIX Printing System 1.2.0

CUPS 1.2.0 is now available for download from the CUPS web site at:

    http://www.cups.org/software.html

CUPS 1.2.0 is the first stable feature release in the 1.2.x series and includes over 90 new features and changes since CUPS 1.1.23, including a greatly improved web interface and "plug-and-print" support for many local and network printers. For a complete list of changes and new features, please consult the "What's New in CUPS 1.2" document at:

    http://www.cups.org/documentation.php/whatsnew.html

CUPS provides a portable printing layer for UNIX®-based operating systems. It has been developed by Easy Software Products to promote a standard printing solution for all UNIX vendors and users. CUPS provides the System V and Berkeley command-line interfaces.

CUPS uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon ("LPD") Server Message Block ("SMB"), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality. CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real-world printing under UNIX.

CUPS includes an image file RIP that supports printing of image files to non-PostScript printers. A customized version of GNU Ghostscript 8.15 for CUPS called ESP Ghostscript is available separately to support printing of PostScript files within the CUPS driver framework. Sample drivers for Dymo, EPSON, HP, OKIDATA, and Zebra printers are included that use these filters.

Drivers for thousands of printers are provided with our ESP Print Pro software, available at:

    http://www.easysw.com/printpro/

CUPS is licensed under the GNU General Public License and GNU Library General Public License. Please contact Easy Software Products for commercial support and "binary distribution" rights.

  10. Back-Channel API; The new back-channel API provides backends and filters with access to information sent back from a printer
CUPS Imaging API
  1. Image API; The new image API provides access to image files of arbitrary size and is based on the CUPS 1.1.x private image filter APIs
  2. Raster API; The raster API provides new functions to read and write the version 2 raster page headers, and a new function to generate a page header from marked PPD options
Scripting Support
  1. PHP Bindings; The PHP language bindings have been revamped to be more consistent with the CUPS API and are now officially supported and installed by default if you have PHP installed on your system

06 Aug 2005Netgear WGPS606 Printer Configuration Mini HowTo

I had a terrible time getting my HP1200 configured on the Netgear WGPS606 as a linux only user. These are the simple steps on how to go about configuring it.

*NOTE: You can still set up the printer with pre V1.0_020 firmware, but you will have to do “Start Printer” after every job, and expect PCL errors, half completed jobs or jobs that spool but never print.**

*NOTE 2: Unfortunatly, printing multiple copies doesn’t work. To get around this problem, print to a file and then use the following script…**

Script:

#!/bin/bash

function is_int() { [ “$1” -eq “$1” ] > /dev/null 2>&1 return $? }

i=0 if ! is_int $1 || [ -z $2 ]; then echo “$0: USAGE: $0 " exit 1 fi

if [ ! -e $2 ]; then echo “$0: $2: File does not exist.” exit 2 fi

while (( $i < $1 )); do lp $2 let i=$i+1 done

Below added December, 20, 2006 *NOTE 3: Mac OSX Tiger (10.4) ships with CUPS 1.1. This device can be used through the Print & Fax pane under your System Prefences. (See Below)**

24 Jun 2005Why Am I No Longer Able To Control My Printing System?

Your printing system is acting funny and you don’t know why. You can’t access printers, you can’t use the web interface, you aren’t allowed remote access, everything your system should be doing, it’s not. All the settings you’ve made in the cupsd.conf file are being erased. Your printing system has gone on strike. What do you do?

This is usually caused by the Linux cups-config-daemon program, which overwrites changes to the /etc/cups/cupsd.conf file with whatever defaults they have assigned for your security configuration.

Run the following commands as root to disable this program:

/etc/init.d/cups-config-daemon stop ENTER /sbin/chkconfig cups-config-daemon off ENTER


23 Jun 2005CUPS Driver Development Kit 1.0.1

Version 1.0.1 of the Common UNIX Printing System Driver Development Kit is now available for download from the CUPS web site at:

 http://www.cups.org/ddk/software.html

The new release fixes some problems in the ppdc and ppdi utilities and supports MacOS X 10.4. It also adds man pages for the raster filters.

The CUPS Driver Development Kit (DDK) provides a suite of standard drivers, a PPD file compiler, and other utilities that can be used to develop printer drivers for CUPS and other printing environments. CUPS provides a portable printing layer for UNIX®-based operating systems. The CUPS DDK provides the means for mass-producing PPD files and drivers/filters for CUPS-based printer drivers.

The CUPS DDK is licensed under the GNU General Public License. Please contact Easy Software Products for commercial support and “binary distribution” rights.


18 Jun 2005CUPS Driver for Windows v6.0 Nearing Release

We have made major progress on the new CUPS driver for Windows, and will be doing a release candidate very soon. The new driver adds support for the page-label and job-billing options that are missing from the standard Windows PostScript driver.

The new driver adds three files to the Microsoft PostScript driver: cups6.ini, cupsps6.dll, and cupsui6.dll. The .DLL files are available both as precompiled binaries and as source code provided under the GNU General Public License. You can access the current development version of the driver at:

http://svn.easysw.com/public/windows/trunk/

You will need the Microsoft Windows Driver Development Kit and Visual C++ 6.0 or higher to compile the driver source code. The cupsaddsmb program must be updated to use the new driver - source code for the updated program is available in both the CUPS and Windows driver repositories.

The new driver works on Microsoft Windows 2000, XP, and 2003. We have no plans to support Windows NT, Windows 9x, or Windows ME.


17 Jun 2005Printing To Windows Servers With Samba

Printing to Windows Servers with Samba</b>

1) Download SAMBA: http://samba.org

2) Configure CUPS for Samba:

              ln –s `which smbspool` /usr/lib/cups/backend/smb

3) The smbspool program is provided with SAMBA starting with SAMBA 2.0.6. Once you have made the link you can configure your printers with one of the following URIs: smb://servername/sharename smb://username:password@servername/sharename smb://ntdomain;username:password@servername/sharename


15 Jun 2005How Do I Control The Number Of Jobs Kept On My System?

The MaxJobs directive controls the maximum number of jobs that are kept in memory. Once the number of jobs reaches the limit, the oldest completed job is automatically purged from the system to make room for the new one. If all of the known jobs are still pending or active then the new job will be rejected.

Setting the maximum to 0 disables this functionality. The default setting is 500.

You can change the MaxJobs directive by editing the cupsd.conf file.


08 Jun 2005CUPS Driver for Windows Status

We are still working on version 6 of our CUPS-specific driver for Windows. The driver is not yet available, but in the meantime you can use the standard Windows 2000 PostScript driver. Consult the cupsaddsmb man page for instructions.

The old 5.0 driver is not compatible with current releases of CUPS, and if you install the old driver it will not be used by cupsaddsmb.

We will make future announcements here when the new CUPS driver for Windows is available for download.

26 May 2005Printing To A Windows Server With LPD

On the Windows Server:

Start up “TCP/IP Printing Server”:

1) click Start -> Control Panel -> Administrative Tools -> Services

2) Scoll down the list shown and double-click on “TCP/IP Printing Server”

3) Go down to the Startup type field and change Manual to Automatic

4) Click Start Button

On the CUPS system:

Add a printer using the device URI of: lpd://server/name

Replace server with the hostname or IP address of the server and name with the queue name.


19 May 2005How Do I Add My PPD File To CUPS?

There are two ways you can add a PPD file:

1) Use the lpadmin command: lpadmin -p printer -E -v device-uri -i filename.ppd OR

2) Copy the file to /usr/share/cups/model and restart cupsd.


13 May 2005How Do I Fix The Error: "client-error-request-value-too-long"

Here is a quick check list to get you on your way:

  1. Are you trying to print a file >2GB? If so, that doesn’t work in CUPS 1.1.x and earlier.
2. Does the RequestRoot directory (/var/spool/cups by default)
   exist?  If not, "mkdir /var/spool/cups"

3. Does the TempDir directory (/var/spool/cups/tmp by default)
   exist?  If not, "mkdir /var/spool/cups/tmp"

4. Is the disk full?  "df -k /var/spool/cups" will show if
   this is the case.  If the disk is full, delete files to
   free up disk space.

10 May 2005How To Restrict Disk, Memory and CPU Usage

If you are running into a performance problem with disk space, memory and CPU usage, editing one or more of the following directives inside the /etc/cups/cupsd.conf file may aid the situation.

The AutoPurgeJobs directive:

Can be enabled if you are using quotas. This will purge completed jobs once they are no longer needed for quota information. The default setting is No.

AutoPurgeJobs Yes

The PreserveJobHistory directive:

Can be turned off to remove each job’s information from disk as soon the corresponding job is completed, cancelled, or aborted. The default setting is On.

PreserveJobHistory Off

The PreserveJobFiles directive:

Controls whether the document files of completed, cancelled, or aborted print jobs are stored on disk The default setting is Off.

PreserveJobFiles Off

The MaxJobs directive:

Controls the maximum number of jobs that are kept in memory. Once the number of jobs reaches the limit, the oldest completed job is automatically purged from the system to make room for the new one. If all of the known jobs are still pending or active then the new job will be rejected. The default setting is 500. The setting of 0 disables this functionality. Here is an example to keep only 400 jobs intact:

MaxJobs 400

The FilterLimit directive:

Sets the maximum cost of all running job filters. It can be used to limit the number of filter programs that are run on a server to minimize disk, memory, and CPU resource problems. The default limit value of 0 disables filter limiting. An average print to a non-PostScript printer needs a filter limit of about 200. A PostScript printer needs about half that (100). Setting the limit below these thresholds will effectively limit the scheduler to printing a single job at any time. For example:

FilterLimit 200

To enable the changes in the configuration file, restart the cupsd daemon.

CUPS also stores old jobs on the hard disk in the “/var/spool/cups” directory. To clean things up when the amount of data gets too large or when there are problems starting the CUPS daemon, stop the cupsd daemon and clean the spool directory with the following commands:

/etc/software/init.d/cups stop ENTER rm -f /var/spool/cups/c* ENTER rm -f /var/spool/cups/tmp/* ENTER /etc/software/init.d/cups start ENTER


10 May 2005How To Allow Printing Jobs From Certain Computers

To allow printing from certain computers, edit the /etc/cups/cupsd.conf file and find the directive.

There you can add or edit the Order, Allow, and Deny directives to your liking. Here are two examples:

# Allow printing from # itself and computers 192.10.2.5 and 192.10.2.6

… Order deny,allow Deny from all Allow from 127.0.0.1 Allow from 192.10.2.5 Allow from 192.10.2.6 </Location>

# Allow printing from # itself and all computers on subnet 192.10.2.x

… Order deny,allow Deny from all Allow from 127.0.0.1 Allow from 192.10.2.0/255.255.255.0 </Location>

To enable the changes in the configuration file, restart the cupsd daemon.


10 May 2005How To Allow Printing Jobs From Certain Computers To A Certain Printer

To allow printing from certain computers to a certain printer, edit the /etc/cups/cupsd.conf file and see if the <Location /printers/printer_name> is already present.

Otherwise, create it with these two lines:

<Location /printers/printer_name> </Location>

The printer_name portion represents the printer queue name that you have configured already.

Between the above two lines, you can add or edit the Order, Allow , and Deny directives to your liking.

Here are two examples:

# Allow printing to printer MyLaserJet from # itself and computers 192.10.2.5 and 192.10.2.6 <Location /printers/MyLaserJet> … Order deny,allow Deny from all Allow from 127.0.0.1 Allow from 192.10.2.5 Allow from 192.10.2.6 </Location>

# Allow printing to printer MyLaserJet from # itself and all computers on subnet 192.10.2.x <Location /printers/MyLaserJet> … Order deny,allow Deny from all Allow from 127.0.0.1 Allow from 192.10.2.0/255.255.255.0 </Location>

To enable the changes in the configuration file, restart the cupsd daemon.


10 May 2005How To Allow Printing Jobs From Certain Computers To A Certain Class Of Printers

To allow printing from certain computers to a certain class, edit the /etc/cups/cupsd.conf file and see if the <Location /classes/class_name> is already present. Otherwise, create it with these two lines:

<Location /printers/class_name> </Location>

The class_name portion represents the printer class name that you have configured already. Between the above two lines, you can add or edit the Order, Allow, and Deny directives to your liking. Here are two examples:

# Allow printing to class MyLaserJet_class from # itself and computers 192.10.2.5 and 192.10.2.6 <Location /classes/MyLaserJet_class> … Order deny,allow Deny from all Allow from 127.0.0.1 Allow from 192.10.2.5 Allow from 192.10.2.6 </Location>

# Allow printing to class MyLaserJet_class from # itself and all computers on subnet 192.10.2.x <Location /classes/MyLaserJet_class> … Order deny,allow Deny from all Allow from 127.0.0.1 Allow from 192.10.2.0/255.255.255.0 </Location>

To enable the changes in the configuration file, restart the cupsd daemon.


10 May 2005How Do I Give My Windows Client Adminstrative Capabilities In CUPS?

From your CUPS server: 1) Goto the text file /etc/cups/cupsd.conf 2) Scroll down the file and put under the <Location/ admin> section: Allow from windowsclientaddress

Now you can use the web interface (http://localhost:631/) with Windows to do administrative tasks.


09 May 2005How To Restrict User Access To A Printer

Two Ways To Restrict User Access To A Printer

1) Use the lpadmin command

The first way and most popular is to use the lpadmin command. The -u option controls which users can print to a printer. The default configuration allows all users to print to a printer:

/usr/sbin/lpadmin -p printer -u allow:all

Along with your list of users, you can specify whether they are allowed or not allowed to use the printer: The below command allows peter, paul, and mary to print to the named printer, but all other users cannot print.

/usr/sbin/lpadmin -p printer -u allow:peter,paul,mary

The following command has the opposite affect:

/usr/sbin/lpadmin -p printer -u deny:peter,paul,mary

All users except peter, paul, and mary will be able to print to the named printer.

The allow and deny options are not cummulative. That is, you must provide the complete list of users to allow or deny each time. Also, CUPS only maintains one list of users - the list can allow or deny users from printing. If you specify an allow list and then specify a deny list, the deny list will replace the allow list - only one list is active at any time.

2) Edit /etc/cups/printers.conf file

The second method is similar to the first since it changes the same configuration file. Instead of issuing the lpadmin command, edit the /etc/cups/printers.conf file to add users to the AllowUser and DenyUser directives within a printer definition. Here are two examples:

# Deny everyone except for users peter, paul and mary

... AllowUser peter AllowUser paul AllowUser mary

# Accept everyone except for users peter, paul and mary

... DenyUser peter DenyUser paul DenyUser mary
   To enable the changes in the configuration file, restart the cupsd daemon.

# Accept everyone except for users peter, paul and mary

... DenyUser peter DenyUser paul DenyUser mary

To enable the changes in the configuration file, restart the cupsd daemon.


09 May 2005How To Restrict Printer Information Being Sent Out From A Server

Printer browsing allows your server to automatically share its printers with client machines and other servers. To make sure that this printer information is sent to the right computers, edit the /etc/cups/cupsd.conf file. Locate the BrowseAddress directive and then edit or add IP or netmask addresses to your liking. Some examples:

# Broadcasts to all computers through all interfaces

BrowseAddress 255.255.255.255:631

# Broadcast to all computers on the 192.0.2.x network

BrowseAddress 192.0.2.255:631

# Broadcast to computers 192.0.2.14 and 192.0.2.15

BrowseAddress 192.0.2.14:631 BrowseAddress 192.0.2.15:631

# Specific hostname address (must enable HostNameLookups)

BrowseAddress host.domain.com:631

The BrowseAddress directive specifies an address to send browsing information to. Multiple BrowseAddress directives can be specified to send browsing information to different networks or systems.

The default address is 255.255.255.255:631 which will broadcast the information to all networks the server is connected to. This global setting might have the undesired effect of causing your PC dialing into your ISP account for every broadcast occurance. To block this, choose valid broadcast address(es) for your LAN(s) only.

To enable the changes in the configuration file, restart the cupsd daemon.


09 May 2005How To Restrict Printer Information Being Received From A Client Or Server

Printer browsing allows your server to automatically share its printers with client machines and other servers. To make sure printer information only comes from certain servers and clients, edit the /etc/cups/cupsd.conf file. Locate the BrowseOrder, BrowseAllow and BrowseDeny directives and then edit or add IP or netmask addresses to your liking. Some examples:

# Deny from everybody except for servers 192.10.2.3 and 192.10.2.5

BrowseOrder deny,allow BrowseDeny from all BrowseAllow 192.10.2.3 BrowseAllow 192.10.2.5

# Deny from everybody except for servers under 192.10.2.x

BrowseOrder deny,allow BrowseDeny from all BrowseAllow 192.10.2.0/255.255.255.0

To enable the changes in the configuration file, restart the cupsd daemon.


09 May 2005How To Restrict Group Access To A Printer

Two ways of restricting groups from accessing a printer

  1. The lpadmin command

The first way and most popular is to use the lpadmin command. The -u option controls which groups can print to a printer. The default configuration allows all groups to print to a printer:

   /usr/sbin/lpadmin -p printer -u allow:all 

Along with your list of groups, you can specify whether they are allowed or not allowed to use the printer: The below command allows staff, students to print to the named printer, but all other users cannot print.

  /usr/sbin/lpadmin -p printer -u allow:@staff,@students 

The following command has the opposite affect:

  /usr/sbin/lpadmin -p printer -u deny:@staff,@students 

All groups except staff and students will be able to print to the named printer.

The allow and deny options are not cummulative. That is, you must provide the complete list of groups to allow or deny each time. Also, CUPS only maintains one list of groups - the list can allow or deny groups from printing. If you specify an allow list and then specify a deny list, the deny list will replace the allow list - only one list is active at any time.

  1. Edit the /etc/cups/printers.conf file

The second method is similar to the first since it changes the same configuration file. Instead of issuing the lpadmin command, edit the /etc/cups/printers.conf file to add groups to the AllowUser and DenyUser directives within a printer definition. Here are two examples:

# Deny everyone except for groups staff and students

... AllowUser @staff AllowUser @students

# Accept everyone except for groups staff and students

... DenyUser @staff DenyUser @students

To enable the changes in the configuration file, restart the cupsd daemon.


09 May 2005How To Restrict Group Access To A Class Of Printers

Two ways of restricting groups from accessing a class of printers

1) Use the lpadmin command

The first way and most popular is to use the lpadmin command. The -u option controls which groups can print to a printer class. The default configuration allows all groups to print to a printer class:

/usr/sbin/lpadmin -p class -u allow:all 

Along with your list of groups, you can specify whether they are allowed or not allowed to use the printer class: The below command allows staff, students to print to the named printer class, but all other users cannot print.

/usr/sbin/lpadmin -p class -u allow:@staff,@students 

The following command has the opposite affect:

/usr/sbin/lpadmin -p class -u deny:@staff,@students 

All groups except staff and students will be able to print to the named printer class.

The allow and deny options are not cummulative. That is, you must provide the complete list of groups to allow or deny each time. Also, CUPS only maintains one list of groups - the list can allow or deny groups from printing. If you specify an allow list and then specify a deny list, the deny list will replace the allow list - only one list is active at any time.

2) Edit the /etc/cups/printers.conf file

The second method is similar to the first since it changes the same configuration file. Instead of issuing the lpadmin command, edit the /etc/cups/printers.conf file to add groups to the AllowUser and DenyUser directives within a printer class definition. Here are two examples:

# Deny everyone except for groups staff and students

... AllowUser @staff AllowUser @students </Printer> # Accept everyone except for groups staff and students ... DenyUser @staff DenyUser @students </Printer> To enable the changes in the configuration file, restart the cupsd daemon.

08 May 2005PyKota 1.22

PyKota v1.22 is now available.

This minor update doesn’t require any database change, but still provides important new features :

  • The print quote generator is now also web-enabled.
  • The job’s billing code is now saved into the database and can serve as a filter for the data dumper.
  • The banner generator is more powerful and allows printing of admin-supplied dynamically generated information.
  • Several stability improvements and bug fixes.

07 May 2005Tea4CUPS v2.11 is out !

This new release features :

  • Now works with old releases of Python like 2.1
  • Error handling code was improved.
  • Errors in posthooks are ignored because the print job was already printed successfully when they are launched, so there’s no reason to stop the print queue.
  • Technical support contracts are now available and include a free subscription to Official packages.

04 May 2005How Do I Check To See If My PPD File Is Error Free?

PPD files can be tested on-line or from the command line using the cupstestppd program. If you are experiencing difficulties with a printer, use this page to validate the PPD file you are using and report any problems to the author of the file/driver.

Where Do I Find This Program?

To access online:

1) From the homepage click the Printer Drivers button 2) Click Test PPD file 3) Type the filename or hit browse to find the filename you desire 4) Hit Test PPD File

To access from the command-line: /usr/bin/cupstestppd

then…

cupstestppd filename

Note: The cupstestppd program is available on CUPS version 1.17 and higher.

The Test Results:

The cupstestppd program returns a zero for a functional driver and a non-zero for a file containing errors.

The error codes are as follows:

1 Bad command-line arguments or missing PPD filename. 2 Unable to open or read PPD file. 3 The PPD file contains format errors that cannot be skipped. 4 The PPD file does not conform to the Adobe PPD specification.


03 May 2005Why Is CUPS Taking Up A Lot Of CPU Memory And How Can I Fix It?

Number 1: Job History Set Up To Keep Too Many Documents

A common error is the MaxJobs parameters found in /etc/cups/cupsd.conf is being set to 0. What this does is disable the MaxJobs feature, allowing an unlimited amount of files to be kept. If jobs are not purged, a lot of CPU memory is being used.

How do I fix this?

Access your /etc/cups/cupsd.conf file and change the MaxJob to a different number. The default setting is 500.

Number 2: Improperly Configured Printer Sharing

BrowseInterval Let’s say you have 500 printers on your network. You set your Browse Interval to 30. You are forcing 17 printers to be sent every second. Not very efficient.

A good rule of thumb:

Set your BrowseInterval greater than the number of printers.

BrowseTimeout

The BrowseTimeout directive sets the timeout for printer or class information that is received in browse packets. Once a printer or class times out it is removed from the list of available destinations.

A good rule of thumb

BrowseTimeout should be at least twice the amount entered in the BrowseInterval (3 times is even better).

If not, printers and classes will disappear from client systems between updates.


03 May 2005How Can You Track Printing Jobs?

The easiest way to track your jobs is from the web interface located at: http://localhost:631/admin

Just click on the printer you are interested in and see who has used the printer and see all completed and uncompleted jobs.

Tracking Jobs From The Command Line

If you want to see the status of any pending job: lpstat

If you want to see all your completed jobs: lpstat -W completed

If you want to see all the incomplete jobs: lpstat -W not-completed

If you want to see all completed jobs: lpstat -W completed -o

If you want to see your printing activity on a particular printer: lpstat printername

So to see your activiy on printer N2025, you’d type: lpstat N2025

To see everyone’s activty on a printer: lpstat printername -o

As shown before, printername must be replaced by the name of your printer.

Note:For a full explanation of the lpstat command type: man lpstat


25 Apr 2005What Printer Model Is The Printer Using?

To find out this information for printer N2025, you’d type the following command:

lpstat -l -p N2025

To find out about every printer on your network, type:

lpstat -l -p


25 Apr 2005Changing The Printing Prioity For A Queued Job

Use the following format to accomplish this:

lp -q -i

The job priority can be set from 1 to 100, where 1 is the lowest priority and 100 is the highest.

The default in CUPS is 50.

So, if you want to make job 12345 a job priority of 75, you’d type:

lp -q 75 -i 12345


21 Apr 2005How To Assign Printing Administration Capabilities To Users

If you want certain users to have access to administer printers and nothing else, you need to create a group.

FOR LINUX USERS ONLY:

1) From the command line type:

    groupadd (and the name of the group) Then for each user you want to add to that group type: usermod -G nameofgroup nameofperson For example, if I wanted to create a group called printadmin and wanted to add Steve and Debbie to that group, I'd type the following commands: groupadd printadmin usermod -G printadmin Steve usermod -G printadmin Debbie 2) In your cupsd.conf file, add this line: SystemGroup nameofgroup For MacOS X Users 1) Use the Netinfo Manager utility to add the group and users to the group. 2) In your cupsd.conf file, add this line: SystemGroup nameofgroup For All Other Users: 1) Go to the /etc/group file and insert this line format: groupname:x:group id:users,users... For example, if I wanted to create a group named printadmin and wanted to add Steve and Debbie I'd type this: printadmin:x:9999: Steve,Debbie What does x do? Just means this group is only for those listed. What about 9999? Unique number that corresponds to group name. You can use any number as long as it is not taken. You will be able to see which numbers have been taken. 2) In your cupsd.conf file, add this line: SystemGroup nameofgroup

21 Apr 2005CupsClient 1.0.4.0

You want to print from a Windows client directly to Cups? Here it is: A modern WindowsXP-style client to install driver and printer - have a look.


20 Apr 2005ESP Ghostscript 8.15rc3

ESP Ghostscript 8.15rc3 is the third release candidate based on GPL Ghostscript 8.15 and includes an enhanced configure script, the CUPS raster driver, many GPL drivers, support for dynamically loaded drivers (currently implemented for the X11 driver), and several GPL Ghostscript bug fixes. The new release also fixes all of the reported STRs from ESP Ghostscript 7.07.x.

In accordance with the CUPS Configuration Management Plan, you now have until Thursday, May 4th to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

http://www.cups.org/espgs/str.php

Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of ESP Ghostscript, so it is very important that you report any problems you identify using the form.

Changes in 8.15rc3:

  • The ESP Ghostscript utility scripts (ps2ps, ps2pdf, etc.) now try to run the “gs” command in the same directory as the script first. This allows multiple versions of ESP Ghostscript to coexist more easily (Issue #1125)
  • The pswrite device made its dictionary readonly, which caused problems with certain PostScript printers (Issue #1100)
  • ps2epsi failed when invoking sed (Issue #261)
  • The CUPS device now supports 16-bit per color rendering.
  • Fix of the buffer alignment of the drivers “imagen” and “lx5000” (Thanks to Werner Fink from SuSE).
  • Fix to get the TTF engine to work even on 64bit architectures (Thanks to Werner Fink from SuSE).
  • Fix to allow a printer driver to switch the polarity in the case of switching from gray mode into color mode, e.g. with “-dBitsPerPixel=1” (Thanks to Werner Fink from SuSE).
  • Enabled the usage of pipes within -sOutputFile even for the old japanese printers, “alc1900”, and others (Thanks to Werner Fink from SuSE).
  • Corrected the PPD files cbjc600.ppd, cbjc800.ppd, ghostpdf.ppd to be fully Adobe-compliant so that they are accepted by CUPS (Thanks to Werner Fink from SuSE).
  • Antialiasing fix for X screen display (Thanks to Werner Fink from SuSE).
  • 64-bit pointer align fix (Thanks to Werner Fink from SuSE).
  • Fix to copy all image information (Thanks to Werner Fink from SuSE).
  • Fix the opvp problem that fails to handle index colored BW images.
  • The PNG devices were missing from the configure script (Issue #1113)
  • The opvp driver requires both dlopen() and iconv_open() support, which were not checked in the configure script (Issue #1107)
  • RPMs created using the ghostscript.spec file did not include the correct fontpath (Issue #1112)
  • The previous default mapping of stdout to stderr caused problems for some programs (Issue #1108)
  • Re-added section to README which tells that all non-obsolete compile-in drivers and UPP files as listed on linuxprinting.org are included
  • Added remaining old Japanese printer drivers: “dmprt”, “escpage”, “lp2000”, “npdl”, “rpdl” (Thanks to Werner Fink from SuSE for converting them to the new API, Issue #1094)
  • Fixed C99-isms in several add-on drivers that prevented compiles to work on non-C99 compilers (Issue #1104, Issue #1114)
  • Fixed segfault problem of opvp driver on AMD64.
  • Fixed gamma correction bug of opvp driver.
  • Fixed illegal color conversion bug on opvp gray device.
  • Fixed opvp segfault problem caused by Ghostscript 8.15 font rasterization.
  • Fixed lips4v segfault problem caused by Ghostscript 8.15 font rasterization.
  • Fixed Makefile.in to also compile the PNG and JBIG2 stuff
  • Added the free Epson Kowa laser printer drivers for the EPL (non-L) series, the AcuLaser series, and the japanese LP series

13 Apr 2005Setting Job Priorities

CUPS allows you to set job priorities from least important (1) to most important (100).

You use the job-priority command to do this.

If I wanted to set a job-priority of 100 (most important) to my file job.txt, I’d type:

lp -o job-priority=100 job.txt


13 Apr 2005How Do We Print Postscript Files To A Non-PostScript Printer?

Most likely you won’t have to do anything special to accomplish this.

Type:

lp -d printer filename

Sometimes this doesn’t work and you have to add ESP Ghostscript, which can be found on this site to be downloaded.

After you download the software, follow the instructions in the readme file.


13 Apr 2005CUPS Server By IP, Rather Than Name

1) Go to /etc/cups/cupsd.conf file 2) scroll down page, find ServerName and add IP address after it.

For example:

ServerName 192.168.0.1

This allows your IP address to be advertised throughout your network.


13 Apr 2005Administrative Privileges From A Remote Location

1) Go to the text file /etc/cups/cupsd.conf 2) Scroll down the file and put under the <Location/ admin> section:

allow from (whatever machine you want it to pertain to)

Just add an Allow directive for every computer you want to be able to do administrative duties on.

Here is an example:

I want to allow remote access to another computer (IP address is 192.168.10.1).

When I access the text file /etc/cups/cupsd.conf, I get a long list of information. I scroll down until I find the section: <Location /admin>.

It looks like this:

<Location /admin> Order deny,allow Encryption IfRequested Satisfy All AuthType Basic AuthClass System Deny All Allow 127.0.0.1 </Location>

How do I allow remote access to my other computer?

Add another Allow line.

Your updated file should look like this:

<Location /admin> Order deny,allow Encryption IfRequested Satisfy All AuthType Basic AuthClass System Deny All Allow 127.0.0.1 Allow 192.168.10.1 </Location>


08 Apr 2005Absolute Basics For Setting Up Your Printing Network

Setting Up Your Client And Your Server

All the information below can be entered in the cupsd.conf file with your favorite text editor.

For example, if I was using the text editor nedit, I’d type: nedit /etc/cups/cupsd.conf

1) Browsing must be allowed in both the client and the server

By default, CUPS allows browsing. (Redhat, SUSE are turned off by default). So both the client and the server need to be set up to accept browsing.

To accept browsing, scroll down to the Browsing directive in your cupsd.conf file and change the Off to On.

It should now read Browsing On.

2) Make sure the Server is listening to the Client

By default, this should already be set as: Listen *:631

This setting will listen to any address on that network. This is not the default setting for Redhat or SUSE.

If you only wanted it to listen to one network address, you could replace the * with an actual address. For example, Listen 127.0.0.0:631

3) Set up who is allowed to be access the Server

Make sure Allow directive looks like this: Allow from @LOCAL

The default setting for this is: Allow from 127.0.0.1

Why set up as @LOCAL?

Eliminates the need to know other client addresses on the local network

4) Enable broadcasting from your server

BrowseAddress @LOCAL

No browse addresses are set by default

Why set up as @LOCAL?

Eliminates the need to know other client addresses on the local network

05 Mar 2005PyKota 1.21

Summary of changes since 1.21beta :

  • Fixed a recently introduced bug in LPRng specific code.
  • Improved stability wrt manually modified LDAP trees where PyKota specific attributes had been inadvertantly deleted.
  • Improved documentation.
  • Updated some translation files.
  • Moved from CVS to Subversion.

24 Feb 2005PyKota v1.21beta

List of changes since 1.20 : ============================

  • Support Contracts are now available from :

    http://www.librelogiciel.com/techsupport/

  • Third party administration tools like phpPykotaAdmin appeared and begin to be useable.

  • Simplified installation script. Independant script to check for dependencies.

  • Integrated pre/post banners (CUPS only). Banners can be either static files, executables, or pipes. PyKota includes a default tool to generate customizable banners on the fly with accounting information. Banners can be accounted for or not, depending on a runtime configuration directive which can be set on a per printer basis if needed.

  • The data dumper is now also available as a CGI script, and can dump the job history into CUPS’ page_log format (even when using LPRng instead of CUPS). This allows real time integration of other tools like phpPrintAnalyzer and the like.

  • The output of the data dumper is now independant of the database backend being used. This allows third party tools like phpPykotaAdmin to integrate it easily.

  • Each user can now have an overcharging (or underchaging) factor, used when computing the cost of a print job.

  • Duplicate jobs can be denied automatically on a per printer basis.

  • Added an email gateway to allow end users to query their quota information by mail.

  • The location of the configuration files is now configurable.

  • Improved security and documentation.

  • Automated disconnect/reconnect in case of LDAP timeouts.

  • Added TLS support for LDAP.

  • Several new configuration directives added, see the sample configuration file for details.

  • Improved –prototype command line option to edpykota : it can now use most user/group attributes as the prototype for new users/groups.

  • Improved the internal Page Description Languages parsers.

  • Turkish and Traditional Chinese translations were added.

  • Many bug fixes and improvements.


24 Feb 2005accsnmp 1.0

A Perl backend wrapper that accounts for jobs by querying the printer over SNMP for its pagecount before and after the job. Built-in support for job and user blacklisting. Simple accounting function stores user pagecounts in text files. Easily customizable.

09 Feb 2005ESP Ghostscript 8.15rc1

ESP Ghostscript 8.15rc1 is the first release based on GPL Ghostscript 8.15 and includes an enhanced configure script, the CUPS raster driver, many GPL drivers, support for dynamically loaded drivers (currently implemented for the X11 driver), and several GPL Ghostscript bug fixes. The new release also fixes all of the reported STRs from ESP Ghostscript 7.07.x.

In accordance with the CUPS Configuration Management Plan, you now have until Thursday, February 24th to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

http://www.cups.org/espgs/str.php

Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of ESP Ghostscript, so it is very important that you report any problems you identify using the form.


19 Jan 2005GPL Ghostscript 8.15 Integration In Progress

Work has begun on integrating ESP Ghostscript with the GPL Ghostscript 8.15 baseline. We now have a Subversion repository for ESP Ghostscript (http://svn.easysw.com/public/espgs/trunk) which has the following items completed:

  • Import of GPL Ghostscript 8.15 sources
  • Application of CUPS driver patches and configure script changes to support printing from CUPS.
  • Application of shared library patches to support better packaging and integration on Linux.

We will be focusing on testing and documentation now and hope to do a quick 8.15.1 release in the near future.


18 Jan 2005CUPS Web Site Redesign

After several months of development, we have finally finished the redesign of the CUPS web site. The new site offers:

  • Hosted articles, which are searchable and can be attached to projects on the links page or standalone. Articles are currently tagged as news announcements, frequently asked questions, or “how-to” articles.

  • A printer driver database page for publishing your PPD files. The intent is to provide a common repository of PPD files for all CUPS users to enjoy.

  • User accounts, which allow us to provide developer access to each of the CUPS-related projects and site. User accounts are also required to post comments to the site as well to minimize spamming (you can still post anonymously)

In the near future, all of the CUPS software and ESP Ghostscript will be moved to new Subversion repositories administered locally on the CUPS server.

If you run into any problems or have suggestions for the new site, please send an email to webmaster@easysw.com.

Thanks for your continued support of CUPS! We hope you enjoy the new site!


03 Jan 2005Common UNIX Printing System 1.1.23

Hollywood, MD (January 3, 2005) -- Easy Software Products today announced the 1.1.23 release of the Common UNIX Printing System ("CUPS"), an IPP/1.1-based printing system for UNIX®

CUPS 1.1.23 is a bug fix release which fixes two security vulnerabilities reported by Daniel J. Bernstein (djb@cr.yp.to). The new release also contains other minor bug and documentation fixes that are not security related. CUPS is available at:

    http://www.cups.org/

CUPS provides a portable printing layer for UNIX®-based operating systems. It has been developed by Easy Software Products to promote a standard printing solution for all UNIX vendors and users. CUPS provides the System V and Berkeley command-line interfaces.

CUPS uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon ("LPD") Server Message Block ("SMB"), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality. CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real-world printing under UNIX.

CUPS includes an image file RIP that supports printing of image files to non-PostScript printers. A customized version of GNU Ghostscript 7.07 for CUPS called ESP Ghostscript is available separately to support printing of PostScript files within the CUPS driver framework. Sample drivers for Dymo, EPSON, HP, and OKIDATA printers are included that use these filters.

Drivers for thousands of printers are provided with our ESP Print Pro software, available at:

    • Fixed an offset bug in the PDF filter (Issue #284)
    • The cupsDoRequest() and cupsDoFileRequest() functions did not map several HTTP status codes to their IPP counterparts. This made detecting certain conditions very difficult (Issue #277)
    • Config, spool, and status files are now owned by the scheduler user (usually root) with read permission for the filter group (Issue #283)
    • The HP-GL/2 filter did not support the SI command, some values for the AD and SD commands, and did not rotate labels properly via the DI command (Issue #282)
    • The fax support did not update/set the job-hold-until attribute when a fax job fails (Issue #269)
    • The cupsLangGet() function didn't support locales of the form "ll.charset" (Issue #271)
    • The scheduler did not use the charset when getting the language localization for a request; this caused extra disk IO for every request (Issue #271)
    • The scheduler did not support requests with more than one language specified (Issue #267)


    17 Sep 2003Alambic 1.0

    Alambic 1.0 has just been released.

    In accordance with the CUPS Configuration Management Plan, you now have until Friday, September 19th to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

        http://www.cups.org/str.php
    
    
    

    Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of 1.1.20, so it is very important that you report any problems you identify using the form.

    CUPS 1.1.20 is primarily a bug fix and performance tuning release and includes fixes for 64-bit platforms, deadlock problems in the signal handling code, PDF printing issues, web interface issues, and various operating system-specific issues. The new release also adds new CUPS API functions for reading and writing files via HTTP, performing authentication, and controlling the required PPD conformance level.

    Changes in CUPS v1.1.20rc1:

    • The scheduler now waits up to 60 seconds before restarting to allow active jobs to complete printing and pending requests to be processed (Issue #226)

    • Added new cupsDoAuthentication(), cupsGetFd(), cupsGetFile(), cupsPutFd(), and cupsPutFile() functions to the CUPS API (Issue #112)
    • The PDF filter always scaled and offset pages; this caused problems under MacOS X, so now the "fitplot" option controls whether PDF files are scaled to fit within the printable area of the page (Issue #250)
    • The LPD backend did not support the port number in a URI (Issue #247)
    • Some filters didn't properly support boolean options (Issue #249)
    • Landscape PDF files were not always offset by the correct amount when rotating (Issue #243)
    • The scheduler could hang in a call to localtime() when logging messages from the signal handler (Issue #242)
    • The PDF filter no longer prints form widgets; this duplicates the behavior of Acrobat Reader (Issue #241)
    • cupsGetPPD() didn't handle a late termination of a HTTP connection with the server (Issue #220)
    • ppdOpen() did not correctly check for "*PPD-Adobe-4." on the first line of a PPD file. This caused incorrect PASS results for some PPD files (Issue #233)
    • cupsEncodeOptions() did not allow boolean options to use "yes" and "on" for true values (Issue #227)
    • The pstops filter only sent the TBCP exit sequence if it was defined in the JCLEnd attribute in the PPD file (Issue #224)
    • Support for more than 1024 files was broken on Solaris 9 (Issue #217)
    • The setgroups() calls now pass in 1 group (the configured group) instead of 0 for compatibility with BSD and Darwin (Issue #213)
    • The scheduler's built-in broadcast throttling was ineffective since incoming packets would cause the next group of outgoing packets to be sent immediately rather than waiting for the next time slot (Issue #211)
    • Added a new ppdSetConformance() function to set the conformance requirements for PPD files. Currently only two levels are defined, PPD_CONFORM_RELAXED and PPD_CONFORM_STRICT, and the default is the relaxed level (Issue #212)
    • The IPP backend did not correctly execute the pictwpstops filter on OSX (Issue #210)
    • The LPD backend did not set the banner class when the "banner=yes" option was specified in the device URI (Issue #209)
    • The imagetoraster filter did not support all of the page device attributes (Issue #208)
    • The pdftops filter incorrectly auto-rotated pages when the user already had specified the proper orientation (Issue #207)
    • Fixed AIX shared library support (Issue #201)
    • Added support for live testing with Valgrind (STR #193)
    • The CGI programs now collect the list of needed attributes for the class, job, and printer template files (Issue #192)
    • The scheduler now passes the first port that is bound to the local loopback or "any" addresses to the CGI programs rather than the port that the browser connected to (Issue #103)
    • The cupstestppd program now checks for bad JobPatchFile attributes and incorrect versions of the Manufacturer attribute for HP printers (Issue #155)
    • The filter makefile incorrectly installed libcupsimage.a in the filter directory (Issue #180)
    • The scheduler did not verify that the job history files define the job-priority and job-originating-user-name attributes (Issue #178)
    • The pstops filter didn't handle poorly-formed binary PostScript files that had CTRL-D's in them (Issue #156)
    • The ppdOpen*() and cupsLangGet() functions did not make a copy of the old locale strings when using the POSIX locale when reading files, which apparently caused problems with some implementations of the standard C library. (Issue #159)
    • The pdftops filter did not work properly with some embedded Type1C fonts (Issue #177)
    • Updated the pdftops filter to be based upon Xpdf 2.02pl1 (Issue #191)
    • The scheduler did not reset the group list when running CGI and filter processes (Issue #185)
    • The scheduler no longer calls malloc and free from the signal handlers (Issue #190)
    • The USB backend now uses the manufacturer and model strings if the description string is not available (Issue #174)
    • The ppdOpen functions still supported the VariablePaperSize attribute, which was removed in v4.0 of the PPD spec. This caused problems with PPD files that relocated the PageSize option to a non-standard group (Issue #158)
    • The cups.list file referenced MAN1EXT, MAN3EXT, and MAN5EXT, but none of those were actually defined (STR #147)
    • Chunked requests could cause a Denial of Service if the connection is terminated before the first byte of chunk data is sent/received (Issue #143)
    • Printers with special characters in their names were not accessible from the web interface (Issue #120)
    • The lpstat command now shows the correct interface script or PPD file, if any, for a print queue (Issue #89)
    • The lpstat command now shows the printer-state-message and printer-state-reasons attributes whenever they are not blank (Issue #152)
    • The French and German option-conflict.tmpl template files did not get installed (Issue #148)
    • The cups.list.in file did not work when compiling without shared libraries (Issue #149)
    • The DSOFLAGS included the LDFLAGS, which causes problems on at least HP-UX (Issue #150)
    • The fax printer support did not keep track of the fax capability bit (Issue #144)
    • The appleLangDefault() function could leak a small amount of memory (Issue #145)
    • The ppdOpen() functions now mirror all normal attributes to the attribute list; previously only certain unassigned attributes would be added (STR #139)
    • The ppdEmitJCL() function wrote JCL commands to stdout instead of the passed file pointer (Issue #142)
    • The httpGets() function could, in certain states, block waiting for data (Issue #132)
    • The cupsEmitJCL() function not outputs an empty @PJL command after the PJL language escape to work around bugs in certain PJL implementations (Issue #131)
    • The cupsEmit*() functions didn't set the orientation value properly (Issue #127)
    • The cups.spec file didn't list the rc2.d init directory or the cupstestppd file (Issue #134)

    A denial of service attack vulnerability, Issue #75, was discovered and reported by Red Hat which allows a malicious user to block the CUPS scheduler while servicing a request, effectively preventing other users from accessing the scheduler. This vulnerability exists for both local and remote accesses to all CUPS versions up to and including 1.1.19rc3.

    A patch for CUPS 1.1.18 is available on the STR page. CUPS 1.1.19rc4 and higher do not contain this vulnerability and do not require any additional patches.


    27 May 2003Common UNIX Printing System 1.1.19

    Hollywood, MD (May 27, 2003) -- Easy Software Products today announced the 1.1.19 release of the Common UNIX Printing System ("CUPS"), an IPP/1.1-based printing system for UNIX®

    CUPS 1.1.19 fixes a denial-of-service attack vulnerability and adds support for fast reconfiguration, option retension and defaulting when adding and modifying printers, binary PostScript printing, fax device features, custom web applications via CGI, PHP, Java, and Python, and simple scripting support for Java, Perl, and PHP. The new release also contains bug fixes including the LPD printing and Solaris signal handling bugs. CUPS is available at:


    18 May 2003SAMBA Printing How-To (with emphasize on CUPS) 0.94beta9

    The Draft for the Printing Chapter of the new Samba 3.0 HOWTO-Collection has been updated. The version now is 0.94beta9. (That means I regard it as 94% finished…. hmmm, the last 6% seem to be harder than the first 60 ;-)

    It is available at

     http://www.linuxprinting.org/kpfeifle/SambaPrintHOWTO/
    

    A PDF version (for convenient printing) is also there.

    This is from the document’s Changelog:


    06-05-2003: a lot of typos corrected – most is spellchecked now checked some of my recipes (they still worked ;-) wrote a few sentences about printing from Samba to CUPS include more rundll32 examples (one using also “runas”)

    17-05-2003: integrated most of the feedback comments from various people. A lot of feedback from Ken Sarkies – thanks a lot! Ciprian Vizitiu crafted the PNG flowcharts from my original ASCII art. Wow! (a few bugs and typos in the PNGs need to be corrected.) —————————————————————————-

    The Samba 3.0 HOWTO-Collection is due for publication alongside the Samba 3.0 software release, probably sometime in May/June. The complete collection of docus is already greatly enhanced and extended, compared to the 2.2.x versions, and so is the printing part. (BTW, most of this is valid for 2.2.x printing too…)

    You can help to further polish it: read it - use it - test its advices & recipes - feed your suggestions back to me. Especially useful at this point are checks for the accuracy of descriptions regarding Windows 2000 + Windows NT (and even Windows 9x) clients. Since I have done most of the work with WinXP clients, you should check if the docu is usable for WinNT/2K too. Also, my Windows UI is German and error messages pop up in German – so had to translate it into English. Please check for inaccurately translated strings and descriptions.

    The most recent PDF version of the complete HOWTO Collection is (until final release) available at

    http://samba.org/~jht/NT4migration/Samba-HOWTO-Collection.pdf
    

    and also in the Samba HEAD CVS. (Note that this does not yet include my Samba Printing HOWTO. The printing chapter(s) contained there will be completely replaced.)

    Thanks, Kurt

    The fourth release candidate for version 4.4 of ESP Print Pro is now available for download from the ESP Print Pro web site at:

        http://www.easysw.com/printpro/rc.php
    
    
    

    This release candidate will be available for testing until Friday, May 28th. Please test this release candidate to determine if there are any high-priority problems and report them using the problem report form at:

        http://www.easysw.com/printpro/support.php
    
    
    

    Bug reports may also be filed using the form at:

        http://www.easysw.com/printpro/rcbug.php
    
    
    

    Reports sent to the ESP Print Pro newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of 4.4, so it is very important that you report any problems you identify using the form.

    ESP Print Pro 4.4 is based on CUPS 1.1.19 and adds support for MacOS X 10.2.x and client support for Windows NT 4.0, Windows 2000, and Windows XP. The new release also adds drivers for several new EPSON and Lexmark printers and supports printing of binary PostScript files to most printers.

    Note for all users: The 4.4 release has increased the conformance requirements for PPD files in order to improve software stability and may not work with existing installed PPD files. The "cupstestppd" utility can be used to manually diagnose and fix PPD files in the /etc/cups/ppd directory, or you can use the "Modify" action in the printer manager to install updated PPD files for your printers. We apologize for any inconvenience this may cause.


    13 May 2003Common UNIX Printing System 1.1.19rc5

    The fifth release candidate for version 1.1.19 of the Common UNIX Printing System ("CUPS") is now available for download from the CUPS web site at:

        http://www.cups.org/software.html
    
    
    

    In accordance with the CUPS Configuration Management Plan, you now have until Tuesday, May 27th to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

        http://www.cups.org/str.php
    
    
    

    Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of 1.1.19, so it is very important that you report any problems you identify using the form.

The new release also contains bug fixes including the LPD printing and Solaris signal handling bugs.

    Changes in CUPS v1.1.19rc5:

    • Jobs with banner pages that were printed to implicit classes would get double banner pages for each file/banner in the job (Issue #68)
    • The mime.convs file was missing the filter definition for Windows BMP (image/x-bitmap) files (Issue #85)
    • The scheduler allowed some READ-ONLY job attributes to be set, which could cause the scheduler to fail on the next restart (Issue #82)
    • The lp and lpr commands did not report when the scheduler was not responding; instead, the user would incorrectly see a "no default destination" error (STR #70)
    • cupsLangGet() could fail on OSX due to a corrupt language preference (Issue #78)
    • Added more checks for HTTP request timeouts.
    • The scheduler dropped the first non-alpha character after an open brace when doing attribute substitutions in banner pages (Issue #77)
    • The scheduler child might send SIGUSR1 to the parent before the signal handler was installed; this didn't prevent the scheduler from starting but produced an annoying error message (Issue #45)


    07 May 2003PyKota 1.07

    An important file was forgotten which forbid the new “external” accounting methods feature introduced in version 1.05 to work properly. However there’s no need to upgrade yet if you don’t plan to use this new feature

    Changes in CUPS v1.1.19rc4:

    • The lp command did not accept "-" for printing from the standard input as required by POSIX 1003.1 (STR #59)
    • Added the job-originating-host-name information for the page_log file documentation in the SAM (Issue #31)
    • The German web interface templates did not use the right paths for job operations (Issue #54)
    • The scheduler would consume all available CPU if started with a pending job in the queue (Issue #35)
    • The polling daemon allocated an extra localization buffer but did not free it, causing cups-polld to eventually use all available memory (Issue #40)


    30 Apr 2003SAMBA Printing How-To 0.75beta3

    Kurt Pfeifle has written a Draft for the Printing Chapter of the new Samba-3.0 HOWTO-Collection. It is available at

    http://www.linuxprinting.org/kpfeifle/SambaPrintHOWTO/Samba-HOWTO-Collection-3.0-PrintingChapter-3rd-draft.html

    A PDF version (for convenient printing) is at

    http://www.linuxprinting.org/kpfeifle/SambaPrintHOWTO/Samba-HOWTO-Collection-3.0-PrintingChapter-3rd-draft.pdf

    The new HOWTO-Collection is due for publication alongside the Samba 3.0 software release, probably sometime in May/June. The HOWTO Collection in all its draft components is already greatly enhanced and extended, and so is the printing part. Please help polish it even further..

    Please: read it - use it - test its advices & recipes - feed your suggestions back to me. This way you can make the Samba Printing Documentation a better one. (You may also learn a bit from it at no cost at all… ;-)

    The most recent PDF version of the complete HOWTO Collection is (until final release) available at

    http://samba.org/~jht/NT4migration/Samba-HOWTO-Collection.pdf

    (Note that this does not yet include my Samba Printing HOWTO part I am asking you to check and test.)

    The printing draft contains 15 ASCII art flowcharts trying to to clarify and explain various aspects of Windows –> Samba printing and of CUPS printfile processing. However, I am not able to convert this into something “nice”. So here goes the call to all who are willing and able to help out with their abilities to use one of the Free Software drawing or graphic programs: please provide some better illustrations for this important documentation.


    30 Apr 2003PyKota 1.05

    The most important new feature is the possibility to use ANY external command of your choice to compute each job’s size, so people who can’t use SNMP or AppleTalk, or prefer to do accounting prior to each job being sent to the printer, instead of always being one job late, can now use whatever command they see fit !


    30 Apr 2003Foomatic 3.0.0

    After meeting some printing developers on the Foomatic workshop on the LinuxTag in June 2003 and further discussion on the foomatic-devel mailing list several ideas came up which lead us to develop the this new major version of Foomatic.

    The most important new features of Foomatic 3.0.0 (compared to 2.0.x) are:

    • One unique filter (foomatic-rip) for all spoolers

    • For all spoolers PPD files are used to provide the printer capabilities information

    • Foomatic-generated PPD files are absolutely Adobe-compliant

    • With foomatic-rip manufacturer-supplied PPD files of PostScript printers can be used with every spooler

    • foomatic-rip processes PostScript according to Adobe’s DSC (Document Structuring Conventions)

    • With PDQ one can print a wide assortment of file types now, and even set up raw printers

    • Custom page size support with all spoolers

    • Information about non-printable margins is put into the PPD files

    • Option settings cannot only be applied to the whole document, but also to selected pages

    • Options are ordered in logical groups for a more clear arrangement in graphical user interfaces

    • “PrintoutMode” option to select from pre-configured quality levels (“draft”, “normal”, “high”, “photo”), sets all quality-related options accordingly

    • String and password options (for example for fax servers or for user restrictions)

    • Several improvements on the linuxprinting.org web site

    See the announcement for more detailed information about the new features.

    To know how to use the new Foomatic via this web site or by installing the whole system on your machine is described on our Foomatic page. From now on there are only the filters and PPDs of Foomatic 3.0.x available on this web site.

    Note: If you are using CUPS 1.1.19 with Foomatic you need Foomatic 3.0.0 or later as this CUPS version requires fully Adobe-compliant PPDs.

    This is not the end of the development of Foomatic. Bug reports, feature requests, and contributions are welcome. Have a look at our Contributions page and post your comments on the “foomatic-devel”list/newsgroup on linuxprinting.org.

    Happy printing!

The new release also contains bug fixes including the LPD printing and Solaris signal handling bugs.

    Changes in CUPS v1.1.19rc3:

    • The scheduler could get in an infinite loop cancelling jobs using "cancel -u user dest" (Issue #48)
    • The "cancel -u user" command did nothing (it should cancel all jobs on all printers owned by the named user - Issue #48)
    • The scheduler would write 0-length job control files (Issue #46)
    • Updated the French man pages (translation provided by Gilles QUERRET)
    • The scheduler would delete all printers from printers.conf if a job was active when a HUP signal was handled (Issue #47)
    • The cups-polld program would leak memory if it was unable to send browse packets to the loopback interface (Issue #40)
    • The scheduler did not put the job-originating-host-name attribute in the job attributes group.
    • The text filter did not default to wrapping text as defined by the IPP implementation document.
    • Scan backends first, PPDs second (Issue #37)
    • Updated the Netatalk documentation in the SAM (Issue #38 and #39)
    • The test suite sent text files to a non-PS print queue, which requires ESP Ghostscript (provided separately). Now send the JPEG test file (Issue #33)
    • The test suite did not show the estimated disk space requirements (Issue #33)
    • The test suite did not set the MaxLogSize directive to 0 to prevent log file rotation (Issue #33)
    • The test suite still setup the old CUPS Ghostscript symlinks (Issue #33)
    • The pstops filter did not report the correct number of copies for the page_log file when printing collated copies to a printer that doesn't support them in hardware (Issue #32)
    • cupsLangGet() needs to set the CTYPE locale to "C" (POSIX) to avoid erroneous tolower/toupper values (fix suggested by Bjoern Jacke)
    • Fixed a typo in the cups.list.in file.
    • Updated all of the Western European locales to default to ISO-8859-15 (for Euro support, suggested by Bjoern Jacke)
    • Updated the German message catalog (update provided by Bjoern Jacke)


    25 Apr 2003PyKota 1.04

    This version now fully support both CUPS and LPRng. Some minor bugs were also fixed.


    18 Apr 2003Common UNIX Printing System 1.1.19rc2

    Subject: ANNOUNCEMENT: Common UNIX Printing System 1.1.19rc2

    The second release candidate for version 1.1.19 of the Common UNIX Printing System ("CUPS") is now available for download from the CUPS web site at:

        http://www.cups.org/software.html
    
    
    

    In accordance with the CUPS Configuration Management Plan, you now have until Friday, May 2nd to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

        http://www.cups.org/str.php
    
    
    

    Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of 1.1.19, so it is very important that you report any problems you identify using the form.

    CUPS 1.1.19 adds support for fast reconfiguration, option retension and defaulting when adding and modifying printers, binary PostScript printing, fax device features, custom web applications via CGI, PHP, Java, and Python, and simple scripting support for Java, Perl, and PHP. The new release also contains bug fixes including the LPD printing and Solaris signal handling bugs.

    Changes in CUPS v1.1.19rc2:

    • cupsLangGet() now sets the encoding field based on the trailing charset in the locale name, and doesn't look for a message catalog in a specific locale.charset directory. This fixes Issue #26 and is more in line with the CUPS 1.2 implementation.
    • The configure script now aborts if the "ar" command or compilers cannot be found.
    • The static cupsimage library was not built by default.
    • The path for the "ln" command was hardcoded in Makedefs.in instead of being checked at configure time (Issue #28).
    • Banner pages containing unescaped { characters would not work.
    • The printer-state-time collection attribute was encoded as an enumeration instead of an integer.
    • The printer-is-accepting-jobs collection attribute was was not added to the collection value.
    • The printer-state-sequence-number collection attribute was not added to the collection value.
    • Fixed typo and const mismatch in IPP backend.
    • Updated the man pages for the new configuration directives.
    • Updated the SAM for MacOS 10.2, the CUPS drivers for windows, the available LPD backend options, and the new configuration directives.
    • The imagetops filter didn't position images properly on the page (Issue #18)
    • The configure script didn't add CPPFLAGS to the compiler options or LDFLAGS to the DSO options (STR #13)
    • The scheduler would try to write a debug log message when starting a job that contained a NULL string. Since not all versions of snprintf() support NULL string pointers this caused some problems (Issue #20)
    • The testipp program now supports reading of IPP message files such as those used for the job history in /var/spool/cups.


    17 Apr 2003PyKota 1.03

    Major features were added : group quotas are finally supported, possibility to limit printing by page quota or by account balance value, price per page and per job defineable for each printer, jobs history which will allow by-period reports in the future, support for AppleTalk printers, workaround for HP printers’ “feature” of not saving their internal counter in real time, database upgrade script for old versions of PyKota, etc…

    The bug concerning page-ranges and embedded documents has been fixed.


    11 Apr 2003Common UNIX Printing System 1.1.19rc1

    The first release candidate for version 1.1.19 of the Common UNIX Printing System ("CUPS") is now available for download from the CUPS web site at:

        http://www.cups.org/software.html
    
    
    

    In accordance with the CUPS Configuration Management Plan, you now have a minimum of two weeks to test this release candidate to determine if there are any high-priority problems and report them using the Software Trouble Report form at:

        http://www.cups.org/str.php
    
    
    

    Reports sent to the CUPS newsgroups or mailing lists are not automatically entered into the trouble report database and will not influence the final production release of 1.1.19, so it is very important that you report any problems you identify using the form.

    CUPS 1.1.19 adds support for fast reconfiguration, option retension and defaulting when adding and modifying printers, binary PostScript printing, fax device features, custom web applications via CGI, PHP, Java, and Python, and simple scripting support for Java, Perl, and PHP. The new release also contains bug fixes including the LPD printing and Solaris signal handling bugs.

    Changes in CUPS v1.1.19rc1:

    • Added CUPS support files for Java, Perl, and PHP (located in the "scripting" subdirectory...)
    • The scheduler now supports fast-reloads of the cupsd.conf file when it is updated via HTTP.
    • The scheduler always changed the ownership of log files; it now only does so if they are not in the /dev directory (i.e. don't want to change the ownership and permissions of /dev/null...)
    • Added libpaper support (patch from Jeff Licquia)
    • Added a new istring() rule for MIME types files that does a case-insensitive comparison of strings.
    • The cups-lpd mini-daemon now sends jobs to the default queue when an empty queue name (or "lp" and there is no "lp" queue) is sent.
    • The scheduler now supports fax queues identified by a "*cupsFax: True" attribute in the PPD file. When a job can't be sent, it is held for 5 minutes by default while other jobs are attempted. The FaxRetryLimit and FaxRetryInterval directives control the number of retries and the time between retries.
    • The scheduler now preserves the default options of PPD files when modifying/upgrading an existing PPD file. When installing a new printer, the scheduler sets the default media size to Letter or A4 as appropriate for your locale.
    • The scheduler no longer limits the number of BrowseAddress, BrowsePoll, BrowseRelay, Listen, Port, SSLListen, and SSLPort directives to 10.
    • The scheduler now supports print files that have been compressed using gzip.
    • The scheduler used the stdio functions to read any job ticket information in a PostScript print job. Since some platforms limit the number of stdio files to 256, job ticket information was ignored when the server had a large number of clients connected to the system.
    • Filters and backends may now report the total number of pages ("PAGE: total NNN") to the scheduler.
    • The LPD backend now supports timeout and sanitize_title options (default to 300 and yes, respectively) and has some additional changes to reduce the chances of multiple copies being printed when only one copy was requested.
    • Fixed a polygon drawing bug in the HP-GL/2 filter.
    • Added a robots.txt file to the standard install to prevent search engines from indexing the CUPS server.
    • Added support for STATE: messages (printer-state-reasons), printer-state-history, and printer-state-time to the scheduler.
    • When using RunAsUser, the scheduler would initially start any previously queued (pending) jobs with RunAsUser disabled
    • all backends would be running as root.
    • If a backend failed for a printer, CUPS would incorrectly requeue the job for printing again.
    • Added support for IPP collections and files.
    • Added experimental support for generic CGI scripts and programs, Java, Perl, PHP, and Python to the scheduler. See the file "CGI.txt" for more information.
    • The CUPS API now supports HTTP cookies and the Expect: field.
    • The cancel command now correctly supports the "-u user" option to cancel all jobs for the named user.
    • The Purge-Jobs operation now supports the my-jobs boolean attribute and a new purge-jobs boolean attribute to control whether job history data is purged from the scheduler; the default is false for my-jobs and true for purge-jobs to match the original implementation.
    • The scheduler would not timeout printers when only using SLP browsing.
    • If the scheduler was unable to execute a filter, it would try to restart the job indefinitely until the filter could be executed.
    • When writing BSD printcap files, the scheduler now includes the rm and rp attributes, allowing the file to be exported to LPD clients. [Patch from Dominic Kubla]
    • The scheduler optimization to reference IPP attribute data instead of performing a full copy caused problems when the referenced data was deleted before it was sent. It now only references attributes that change only when the scheduler is restarted. The change also reduced the memory footprint of a printer object to 2k.
    • The scheduler now holds signals while logging messages to avoid potential deadlock issues when handling signals on Solaris 8.
    • The lpadmin command now allows printer access control by group name as well as user name.
    • "lpoptions -l" got in an infinite loop if no default printer was available.
    • The scheduler now logs the job-originating-host-name attribute in the page_log file, and uses "-" for any empty fields (patch from Dominik Kubla).
    • The pdftops filter now scales PDF pages within the printable area of the page.
    • The pstops filter didn't include the page-label and classification boxes when printing EPS or non- conformant PS files.
    • The imagetops filter didn't always correctly position the image on the page when printing in landscape orientation.
    • The ppdEmit() functions now support the RequiresPageRegion attribute when sending InputSlot and ManualFeed commands.
    • The PPD loading code now supports standard options outside of OpenUI/CloseUI as required by the PPD spec.
    • The cupstestppd program has been upgraded to provide a concise PASS/FAIL report, additional detailed conformance testing, and support for gzip'd PPD files.
    • The PPD loading code is now much more strict when loading a PPD file, and tracks more format errors.
    • The scheduler ignored child signals when gathering the list of available devices, when it should have been using the default signal handler.
    • The cupsEncodeOptions() function could encode an option with a NULL last string.
    • The socket backend could report the wrong number of backchannel bytes if an error occurred on the link.
    • The cups-polld program now only sleeps after getting all printers and classes. This allows for longer intervals without excessive delays before classes show up...
    • Added a new httpWait() function to support waiting for data for a specific number of milliseconds.
    • httpGets() now times out after 1 second on non-blocking HTTP connections.
    • The scheduler no longer accepts rangeOfInteger values that are out of order (e.g. 5-1)
    • The sides attribute was incorrectly sent as a name value; it is a keyword value.
    • The IPP backend now detects if the destination queue has gone away and reports an error.
    • The scheduler and HTTP API now allocate their select() sets to support larger numbers of clients on systems that support it.
    • The scheduler now sets the CFProcessPath environment variable under MacOS X.
    • The cupsLangDefault() function now uses the CoreFoundation localization API under MacOS X.
    • The httpSeparate() function didn't handle file URIs of the form "file:///path" properly.
    • The lpadmin command now supports a "protocol" option for specifying the binary communications protocol to use when printing binary PostScript data.
    • The scheduler did not properly parse the SystemGroup directive, so only the first group would be used.
    • Revamped how strings are stored in the scheduler, providing a substantial improvement in memory usage for systems with large numbers of printers.
    • The PostScript filter now supports binary PostScript files and files beginning with the PJL language escape sequence.
    • The PPD API now provides additional information from the PPD file.
    • The USB backend didn't compile on Solaris Intel.
    • The cupstestppd utility now supports the "-q" option (quiet) for use in scripts, etc.
    • Merged several weight-reducing changes into the CUPS baseline donated by Apple.
    • Added preliminary support for CDSA; patch provided by Apple.
    • Implicit classes are now created from identical printer classes on the network.

    • The scheduler now supports URIs in HTTP request lines to conform to the HTTP/1.1 specification.
    • The time-at-xyz attributes were not recognized in banner files if prefixed by a question mark, e.g. "{?time-at-creation}".
    • Added support for pre-filtering application/pictwps files on MacOS clients before sending them to a server via IPP.
    • The scheduler now allows file:/dev/null device URIs even if FileDevices is set to No.
    • CUPS uses strerror() for hostname resolution errors, when it should have used hstrerror().
    • The USB backend no longer tries to guess the serial number of a device from the USB devices file; this means that printers that don't report their serial numbers in the device ID string will not be individually selectable.
    • The pstops filter didn't handle page ranges properly when a page contained an embedded document.
    • Added a translation of the web interface to German.
    • When printing using the OutputOrder=Reverse option with duplexing, the output order is now truly reversed; the order of sub-pages when printing N-up is the same.
    • The pstops filter did not always output the extra blank page when printing a document with an odd number of pages with duplexing enabled.
    • The ippAddXYZ functions no longer allow the application to add less than 1 value.
    • Fixed a URL rewrite bug in the web interface
    • local access was sometimes redirected away from localhost...
    • The ppdOpen() functions could get in an infinite loop if the PPD file contained a keyword or text that was too large for the buffer.
    • Added preliminary support for GNU TLS; patch provided by Jeff Licquia.
    • Now timeout IPP attribute reads after 1 second inside an attribute definition.
    • Now timeout connections that have been shutdown (due to errors) after 30 seconds instead of the Timeout setting (300 seconds by default). This provides faster recovery from DoS attacks.
    • A denial-of-service attack warning message was being written to the log files by the scheduler for every detection. This caused a DoS of its own in some situations. The warning message is now written no more than once per minute.
    • Fixed the CIE colorspace support code in the image and PS RIPs.
    • The job-quota-period, job-page-limit, and job-k-limit attributes were not flagged as integers, so setting quotas would not work.
    • Added an additional response check in the scheduler to more quickly recover from denial-of-service attacks.
    • The cupstestppd file was incorrectly installed in the /usr/sbin directory instead of /usr/bin.
    • The EPM list file did not include the cupstestppd program or man page files.

    08 Jan 2003GIMP-Print Drivers for CUPS 4.2.5pre2

    Gimp-Print 4.2.5-pre2, released December 22, 2002, is a prerelease in the Gimp-Print 4.2 series.

    Gimp-Print is a suite of printer drivers that may be used with most common UNIX print spooling systems, including CUPS, lpr, LPRng, or others. These drivers provide high quality printing for UNIX (including Macintosh OS X 10.2 and newer) and Linux systems in many cases equal to or better than proprietary vendor-supplied drivers, and can be used for many of the most demanding printing tasks.

    This software includes the Print plug-in for the Gimp, and GhostScript and CUPS drivers, including Foomatic data.

    The Print plug-in for the requires the Gimp 1.2.

    The CUPS driver requires CUPS 1.1.9 or higher. 1.1.14 or above is highly recommended, as certain translation-related bugs are fixed and it is possible to print true CMYK.

    The Ghostscript driver requires GNU Ghostscript 5.10, 5.50, 6.51, or any later GNU Ghostscript release based on 6.51 (e. g. 6.52). It may also be used with GNU Ghostscript 7.05, or with ESP Ghostscript 7.05.

    The IJS GhostScript plugin driver requires GNU Ghostscript 6.53 or later, ESP Ghostscript 7.05 or later, or APFL GhostScript 7.04 or later.

    Users of Macintosh OS X 10.2 and above can use this package, as the printing system is based on CUPS, which is supported by Gimp-print. Note that Macintosh OS X 10.0 and 10.1 (including 10.1.5) cannot use this package. We recommend that Macintosh OS X users download the precompiled installer package from

        http://gimp-print.sourceforge.net/MacOSX.php3
    
    
    

    rather than attempt to build this package from source, as using the installer is much simpler. We further recommend that Macintosh OS X users install ESP GhostScript, to permit printing from Carbon applications (such as most Adobe applications) that generate PostScript rather than PDF output. Directions for that are also available at

        http://gimp-print.sourceforge.net/MacOSX.php3.
    
    
    

    Please read the README file for full instructions on installing this package.

    Gimp-Print 4.2.5-pre2 contains the following major changes over Gimp-Print 4.2.5-pre1:

    1. If Foomatic 2.9.x is installed, the Foomatic data will be generated with additional features: Once the options are put into groups ("General", "PrintoutMode", "Adjustment") and a new "PrintoutMode" option will be added, which lets the user choose pre-configurations for common printing tasks, but still adjust the individual options. If an older version of Foomatic is installed, the Foomatic data will stay as before.

    • The configure script did not use the full path to the install-sh script when it was used.
    • The pstoraster filter did not correctly support DuplexTumble mode for printers that used flip duplexing.
    • The cups.list.in file was missing from the distribution.
    • The New DeskJet series driver did not use the correct OrderDependency for the Duplex option.
    • Use read() instead of fread() to read piped print files in lpr/lp. This avoids a bug in the HP-UX 10.20 fread() function.</UL>

    06 Jul 2001CUPS v1.1.9 is Released!

    Hollywood, MD (July 6, 2001) -- Easy SoftwareProducts today announced the 1.1.9 release of the Common UNIXPrinting System ("CUPS"), an IPP/1.1-based printing system forUNIX®

    CUPS 1.1.9 adds support for AIX, adds several performanceimprovements to the scheduler, adds support for the ApacheInclude directive, adds new HideImplicitMembers andImplicitAnyClasses directives, stores user-defined options asdifferences from the system-defined options, adds a"natural-scaling" option for printing images, and fixes a numberof small bugs. Binaries for several platforms are available at:

    CUPS provides a portable printing layer for UNIX®-basedoperating systems. It has been developed byEasy Software Products to promote astandard printing solution for all UNIX vendors and users. CUPSprovides the System V and Berkeley command-line interfaces.

    CUPS uses the Internet Printing Protocol ("IPP") as the basis formanaging print jobs and queues. The Line Printer Daemon ("LPD") ServerMessage Block ("SMB"), and AppSocket (a.k.a. JetDirect) protocols arealso supported with reduced functionality. CUPS adds network printerbrowsing and PostScript Printer Description ("PPD") basedprinting options to support real-world printing under UNIX.

    CUPS also includes a customized version of GNU Ghostscript(currently based off GNU Ghostscript 5.50) and an image file RIP thatare used to support non-PostScript printers. Sample drivers for HP andEPSON printers are included that use these filters.

    20 Feb 2001CUPS v1.1.6-3 Source Update Now Available!

    An updated source distribution for CUPS is now available that fixessome distribution problems. The new distribution also includes severalsecurity and bug fixes:

    • The configure script put the JPEG library before the TIFF library; this caused problems in some configurations since the TIFF library also supports JPEG compression of TIFF images.
    • Updated the configure script and makefiles to handle admin man pages with the "1m" extension (HP-UX, IRIX, Solaris, Tru64) and in odd directories (IRIX)
    • The updated cupsTempFile() function did not return the filename when called with a filename buffer of NULL (previously it used a static buffer.)
    • FreeBSD uses /dev/unlptN, but NetBSD and OpenBSD use /dev/ulptN.
    • DeletePrinter() didn't remove the printer from any classes it was a member of.
    • DeletePrinterFromClass() didn't preserve the implicit status of a class.
    • DeletePrinterFromClasses() didn't remove printers from implicit classes.
    • StartJob() didn't send the job-sheets, job-priority, and job-hold-until attributes to remote printers.
    • LoadAllJobs() was looking for job-sheets-completed instead of job-media-sheets-completed. This would prevent accumulation of page data after a restart of the scheduler.
    • The pstops and imagetops filters now generate copies using the appropriate method for a Level 1, 2, or 3 printer since some Level 2/3 printers don't support the /#copies variable anymore.
    • The man page for cups-lpd did not mention the "-o" option.
    • The IPP backend didn't handle version-not-supported errors and revert to IPP/1.0 (previously it only checked for a bad-request error)
    • Caldera fix: lpc now reports unimplemented commands as unimplemented, not invalid.
    • Caldera fix: lpq didn't recognize BSD lpq "-a" option.
    • Caldera fix: lpr didn't recognize BSD lpr "-1", "-2", "-3", "-4", "-q", or "-U" options.
    • RedHat fixes: patches to GNU Ghostscript
    • SuSE fix: temp file creation patch to GNU Ghostscript (pstoraster).
    • SuSE fix: remove cgi-bin/abort.c and cgi-bin/email.c, which are not used.
    • SuSE fix: missing NULL check in cgi_initialize_post().
    • SuSE fix: potential buffer overflows in cgi_initialize_string().
    • SuSE fix: potential buffer overflows in ippSetCGIVars()
    • SuSE fix: more NULL checks in ppdOpen(); also make sure that all memory is freed on error to avoid memory leaks.
    • SuSE fix: Exit from child if setgid() or setuid() fails.
    • SuSE fix: Added setgroups() calls after setgid() and setuid() calls.
    • SuSE fix: potential buffer overflows in httpEncode64() calls.
    • SuSE fix: potential buffer overflows in httpSeparate()
    • SuSE fix: potential buffer overflows in ippWrite() for bad input.
    • SuSE fix: potential nul skip in ppd_decode() for missing hex digits.</UL>


    07 Feb 2001CUPS v1.1.6-2 Source Update Now Available!

    An updated source distribution for CUPS is now available that fixessome distribution problems. The new distribution also includes severalsecurity fixes:

    • Added changes to support NetBSD startup scripts.
    • Added separate compiler options for pstoraster (Ghostscript) to avoid compiler-induced errors from Ghostscript's twisted code.
    • The mime.types file contained syntax errors.
    • Updated the *BSD USB device filenames to use the /dev/unlptN files so that the USB device is not reset prior to printing (causes print corruption on many printers)
    • Added new cupsTempFd() function to avoid serious security bug in glibc fopen() function. The glibc fopen() function unlinks a file before creating it, which opens up possible symlink attacks. [Editor's note: this appears only to affect a beta release of glibc, not any current production release]
    • Now reject 0-length names in add-printer and add-class requests.
    • Fix for pstoraster when ZLIB is not available.
    • cupsGetPPD() didn't reconnect when a HTTP connection was lost.
    • SuSE fix: httpConnect() didn't check that the value from gethostbyname() was a valid IPv4 address.
    • SuSE fix: httpConnect() didn't allow file descriptor 0 to be used for a socket.
    • SuSE fix: ippRead() didn't confirm that all values in a set were numeric or string types.
    • SuSE fix: lppasswd race condition fixes.
    • SuSE fix: directive names could overflow buffer when reading *.conf files.
    • SuSE fix: HEAD requests for PPD files did not use the same logic as GET requests.
    • SuSE fix: possible buffer overflow when adding /index.html to requested directory name.
    • SuSE fix: possible buffer overflow when converting IPP attributes to string options for filters.
    • SuSE fix: creating file: device output with mode 0666 instead of mode 0600.
    • SuSE fix: creating job info files with mode 0640 instead of 0600.
    • SuSE fix: don't rely on snprintf() for including system name in log filenames.
    • SuSE fix: add bounds checking when copying quoted and hex strings.</UL>


    26 Jan 2001CUPS v1.1.6-1 Source Update Now Available!

    An updated source distribution for CUPS is now available that fixessome distribution problems:

    • Added configure check for getting the correct strftime() format string; %c is not Y2k safe, but %KC and NULL are not universally supported.</UL>


    25 Jan 2001CUPS v1.1.6 is Released!

    CUPS v1.1.6 is now available for download!

    The following changes were made in v1.1.6 (since 1.1.5):

    • Fixed another possible DoS attack in httpGets()
    • Added check for "LANGUAGE = PCL" and "LANGUAGE = POSTSCRIPT" in mime.types.
    • Resolution options were not being passed into the filter programs properly.
    • The default compiler options for GCC no longer includ "-g3", which apparently is deprecated in newer versions of GCC.
    • CheckJobs() could cause cupsd to crash if a job is cancelled in StartJob().
    • The printers.conf and classes.conf files are now written with restricted permissions.
    • The round-robin algorithm used by FindAvailablePrinter() had problems; fixes contributed by Joel Fredrikson.
    • If LoadAllJobs() is unable to determine the file type of a print job, assume "application/vnd.cups-raw".
    • The web interface now provides a job_printer_name value for any corresponding job_printer_uri value.
    • The cups-lpd mini-daemon now logs the client address and hostname as well as all commands and errors in the syslog file.
    • The IPP backend now detects the supported file formats and only specifies the document format if it is supported. This makes IPP printing to network print servers and cards more reliable without affecting the capabilities of CUPS servers.
    • The time_at_xyz attributes are now converted to human- readable dates and times for the web interfaces.
    • The HP and EPSON sample drivers now correctly catch signals and eject the current page when a job is cancelled.
    • Fixed bug in CGI code
    • did not ignore control characters (e.g. newlines) in form data. This caused sporatic web interface problems.
    • The file type logging code in the scheduler referenced the optional document-format attribute; the new code uses the resolved MIME type instead.
    • The client.conf parsing code now removes trailing whitespace.
    • The MaxJobs directive was being treated as a boolean instead of an integer.
    • The scheduler would not timeout remote printers if BrowseInterval was set to 0.
    • The lpadmin command now supports setting of options and user-level access control.
    • Added "-E" option to all printing commands to force encryption.
    • The client code did not consume the response to the OPTIONS request when switching to secure mode.
    • The scheduler did not output a Content-Length field when responding to an OPTIONS request.
    • Added documentation on using cups-lpd with xinetd to the man page.
    • The socket backend now starts retries at 5 seconds and increases the interval to 30 seconds. This should provide faster printing when multiple jobs/files are queued for a printer.
    • The filters and backends no longer buffer output to stderr. This should provide much more accurate status reporting.</UL>
