Unable to print from FF/TB, while it works from Oo.org

Mon Jan 31 12:06:27 CST 2005

Hi there,

Since hoary has been ugly to me, I've resently set up the same box with 
ubuntu-warty. I've just got a regular install, with nothing 
out-of-the-ordinary that I can tell, however I have got some errors that 
I've never seen before.
The one bugging me right now is that I seem to be unable to print from 
Firefox and thunderbird. It works from Openoffice.org, which seems to 
use cups. Thunderbird and Firefox however seem to use postscript. This 
results in the print being sent to nowhere, an occasional glitch in 
cups, or an outright crash to desktop in FF.

Appended cups error log

Regards,

Hidde
