Common UNIX Printing System 1.2.0

Created at 13:59 May 08, 2006 by mike, last modified at 14:00 May 08, 2006

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

    http://www.cups.org/software.php

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:

Changes in CUPS 1.2.0 since 1.2rc3:

• Documentation updates (STR #1618, STR #1620, STR #1622, STR #1637)
• Static file copy buffers reduced from 64k to 32k to work around bogus MallocDebug library assumptions (STR #1660)
• The scheduler did not decode the backend exit code properly (STR #1648)
• The MacOS X USB backend did not report the 1284 device ID, nor did it fix device IDs returned by HP printers.
• The scheduler started more slowly than 1.1.x with large numbers of printers (STR #1653)
• cupsRasterInterpretPPD() didn't support the cupsPreferredBitsPerColor attribute, and imagetoraster didn't use the new API.
• The "make test" script did not create all of the necessary subdirectories for testing (STR #1638)
• The scheduler did not prevent rotation of logs redirected to /dev/null (STR #1651)
• "make test" did not include the SNMP backend in the test environment (STR #1625)
• The EPM packaging files did not work (STR #1621)
• "Use Default Configuration" inserted a broken configuration file (STR #1624)
• Redirects in the web interface did not always preserve the encrypted status of a connection (STR #1603)
• Added the Apple "pap" backend.
• Added CUPS library to CUPS Image shared library linkage to support Linux --as-needed linker option (STR #1606)
• Fixed support for --enable-pie (STR #1609)
• The pdftops filter did not validate the length of the encryption key (STR #1608)
• Updated the Polish localization.
• "Encryption Required" in the cupsd.conf file now only requires encryption when the connection is not over the loopback interface or domain socket.
• Printer names containing "+" were not quoted properly in the web interface (STR #1600)
• The SNMP backend now reports the make and model in the information string so that the auto-generated printer name is more useful than just an IP address.
