Why Am I Getting The Error: client-error-not possible?

Created at 08:04 Jun 15, 2005 by steve, last modified at 07:23 Feb 01, 2006

Possible causes of client-error-not-possible:

    1. Trying to add a class with the same name as a printer.
    2. Trying to add a printer with the same name as a class.
    3. Trying to add a printer using a file: device without
       setting "FileDevice" to "yes" in cupsd.conf.
    4. Trying to add a printer using an unknown device URI or
       scheme.
    5. Trying to cancel a job that does not exist.
    6. Trying to print a file when there are too many jobs in
       the system.
    7. Trying to print a file when you have exceeded your quota
       settings.
    8. Trying to move a job that has already printed.
    9. Trying to release a job that is not held.
    10. Trying to restart a job that is not completed.
    11. Trying to change job options for a job that is completed.
    12. Trying to print a directory.

All of these except #12, which happens on the client side in cupsPrintFiles(), will log a human-readable error in the /var/log/cups/error_log file. Listing

Hello. "client-error-not-possible" message when clicking on restart job. I do this because all jobs have not been printed, even the test page. The jobs appear as cancelled. How can I check what is happenning? Reply

Windows98 -to- samba print share -to- cups does not obey cups' AllowUser=@teachers protocol.   Where "teachers" is the primary group for the user.  The cups log shows - client-error-not-possible.  When we disable AllowUser then printing works.  Printing from Linux workstation obeys the AllowUser protocol - it is just win98 through samba.  We suspect cups/samba is not looking up primary groups only secondary groups or cups/samba is not looking up groups at all.

I don't see how any of those 12 possibilities fits my situation.

Yes, I do have esp ghostscript installed.

Getting 'client-error-not-possible' message, whenever trying to print with cups. Originally, cups admin test page printed fine, but OpenOffice-1.1.3, though it recognized the printer, refused to actually *print* any documents. I upgraded to OpenOffice2.0.2, but no change, except that now, nothing prints. No test page in cups admin, no lpr -P from command line...nothing.

Printer: HP PhotoSmart 7150

I went to the FAQ page, for "Possible causes of client-error-not-possible:"   
    1. Trying to add a class with the same name as a printer.
          -Nope...no classes set up.
    2. Trying to add a printer with the same name as a class.
          -Nope again, same reason as above.
    3. Trying to add a printer using a file: device without
       setting "FileDevice" to "yes" in cupsd.conf.
          -Possible, but I confess I do not understand (exactly) what to   
           add to the cupsd.conf file, to solve this. I did not find a
           section mentioning devices, with a yes/no option in the file.
    4. Trying to add a printer using an unknown device URI or
       scheme.
          -As I said earlier, the test page printed from admin when the 
           printer was first set up. I have tried deleteing and 
           recreating the printer, but it still refuses to print.
    5. Trying to cancel a job that does not exist.
          -Nope. Not this, either.
    6. Trying to print a file when there are too many jobs in
       the system.
          -Sorry; I have deliberately tried only one job at a time.
    7. Trying to print a file when you have exceeded your quota
       settings.
          -Quota set to unlimited. How can one exceed infinity?
    8. Trying to move a job that has already printed.
          -Please. It's not this one, either.
    9. Trying to release a job that is not held.
          -Promising.... Held, where, exactly, and how?
    10. Trying to restart a job that is not completed.
          -Nah. Only one at a time. Incompleted jobs are always   
           cancelled, before new jobs initiated.
    11. Trying to change job options for a job that is completed.
          -Nope.
    12. Trying to print a directory.
          -Sorry; the file's a file, not a directory.

How do I get rid of the error and actually get some (*&%$%&^&$#%&&*%) printing done?

(If you need further information, please be specific about how I should find it. I am certain the problem is nothing for a seasoned admin to solve, but I have tried everything I know how to do, to no avail.)

Thank you,

Seth
