[cups.general] No reaction from Canon iP3100 using CUPS

[Dave M G]

CUPS General List,

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.

I have been seeking help from the Ubuntu mailing list and my local Linux 
user's group. But after several weeks, progress on trying to find the 
problem has stalled. So it is with some amount of desperation that I 
have turned to this list in hopes of finding help.

Before I outline details, please be aware that I am an end-user of 
Linux, and can not be counted on to know all the necessary commands to 
diagnose and solve problems. If any explanations are offered, please 
make them newbie-friendly.

First, the directions I followed for installing the printer can be found 
here:
http://www.techbuilder.org/recipes/showArticle.jhtml?articleId=167600449&printableArticle=true

The main difference is that I have the Japanese model of the printer, so 
the drivers referenced in the article as being available from Canon's 
Japanese site actually match my printer exactly.

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.

This is the current status of my printer. I have, over the last few 
weeks managed to vary the types of errors I've received, by changing 
settings, largely through random experimentation. Earlier today, I 
completely reinstalled CUPS and changed the USB cables to attempt a 
fresh start. But the situation described above is representative of how 
it has been since I got the new computer. At no time since I attached 
the printer to the new computer has it printed anything. (It still 
prints from the old computer, so the printer is working).

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 at homebase:~$ 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)
