I'm at work now so can't post to list. Check the logs in /var/log/cups/ and see if they gives any more clues.
I'm attaching the log I get after installing the printer using the web-interface.
Just so you can compare here is the part of my printers.conf file for my parallel printer:
My parallel printer from /etc/cups/printers.conf
<Printer HPLJ1100> Info Location DeviceURI parallel:/dev/lp0 State Idle StateTime 1164436598 Accepting Yes Shared Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy retry-job </Printer>
Mine looks exactly the same except minor details (having a Canon i550 instead).
Permissions on lp0
# ls -l /dev/lp0 crw-rw---- 1 root lp 6, 0 2007-01-17 05:48 /dev/lp0
Same.
Probably a silly question but I assume you've got all the printing ports installed like gimp-print and foomatic-filters? I don't know whether you need them but I have them installed and all my printing works fine.
Didn't have gimp-print and foomatic-filters since they were marked optional. However, didn't make much change. Still have the same error. Thanks, Helge
