I've installed cups and can print anything from firefox and thunderbird. I cannot print from abiword or mousepad. If I select any print selection in abiword, the program immediately closes without printing. If I select print from mousepad, nothing happens.
I tried rebooting, relogging but nothing changes.
Not quite sure but this looks like a problem with the Gnome (GTK) applications -- firefox/thunderbird are platform independant. Can you check whether your logs provide any clues (/var/log/cups/*)?
The only entry of interest is
Unable to set ACLs on root certificate "/var/run/cups/certs/0" - Operation not supported"
I looked this string up. Seems to be a common error across all distros but no definitive solution found anywhere either. I checked all other logs but nothing appears amiss.
I installed gEdit. It prints as expected. As this is a gnome product I checked whatever gnome objects I could find and found nothing unusual.
I booted abiword in a terminal as myself and root. In both instances when I hit the print preview button I got this message:
** (abiword:2032): WARNING **: IPP request failed with status 1030 Aborted
Looked this one up and found nothing usefull. Now, I don't know if this is an application (abiwork, mousepad) problem, a DE (xfce4) problem, or an OS (Arch) problem. This is beginning to move past the annoying stage.
