Re: [tlug] Printer Not Responding

[Dave M G <martin@example.com>]

TLUG,

I went and completely re-installed CUPS in hopes of getting a fresh 
start, which changed some of the error output. I also posted this 
information to the CUPS mailing list, although it seems actually that 
there's no real traffic there. A few people seeking help and almost no 
one answering.

So, to recap the situation:

I have a Canon Pixus iP3100, and Ubuntu Linux, Dapper Drake 6.04. This 
printer used to be attached to an older computer with Ubuntu Breezy 
Badger 5.10, and worked flawlessly when printing from CUPS. However, 
after upgrading the computer, and following the same installation 
procedure, the printer no longer works.

After re-installing CUPS, I installed the printer using the CUPS 
interface. I used the custom PPD file created following the instructions 
of the site. The printer was connected to my USB port and turned on when 
I installed it.

When I click to print a test page, the printer does not respond in any way.

In the CUPS interface, the status changes to "stopped". The "State" of 
the print job remains "pending" indefinitely. If I try to cancel the 
job, it returns the error:
Error
client-error-forbidden

I can, however, press "Cancel all jobs", then all jobs will be purged, 
and I can restart the printer. However, despite the printer status being 
started, any attempt to print will recreate the conditions outlined above.

Any help would be greatly appreciated. I have included some output from 
the various commands that I have come across below. If there is anything 
else I can do to diagnose or solve this problem, please let me know.

dpkg-reconfigure cupsys
(I did this and went with the default options)

dave@example.com:~$ lpadmin -p Canon -v /dev/usblp0
lpadmin: File device URIs have been disabled! To enable, see the 
FileDevice directive in "/etc/cups/cupsd.conf".
(I attempted to insert a FileDevice directive in cupsd.conf prior to 
re-installing CUPS. Other than removing this error, it had no effect on 
the printer)
