I have had printer problems ever since I switched from XP to Windows nearly a year ago, but not as bad as since I upgraded to Hardy last week....

The printer is a Fuji-Xerox c525a networked printer. I downloaded the driver from the FX website as an rpm, converted it to deb with Alien, and installed it.

When I try and print, the job just gets held. Occasionally it will get through if I'm only printing a page, but mostly that doesn't even work. I have pasted some of the CUPS error log below, with the important bits in red.

Any ideas?

I found a solution!
See it here:
http://ubuntuforums.org/showthread.php?t=483415

As the old saying goes: when in doubt, consult the manual. The problem appears to be that I added the printer using the KDE Add Printer Wizard. It was automatically given a "socket" URI instead of an "lpd" one. When I:
- altered the printer settings at http://localhost:631 (the CUPS admin page) as instructed in the manual for the printer, and
- copied the PPD file into a second place on the hard drive (as instructed on ubunutuforums, see the link above)

..everything started working.

It's still slower than windows, but I can live with that.

I found that the only thing I needed to do was change socket to lpd (and remove :9100 off the end as well). See Solving Ubuntu printer “broken pipe” problem (DocuPrint C525A) . BTW thanks for steering me in the right direction - very grateful.
