I used to be able to print over the network, but then one day I received this message:
/usr/lib/cups/backend/lpd failed
This is a printer that I installed myself through the Administration>Printing (Lucid 10.04 Gnome UI).
From the shell, it looks good:
$ lpq
Xerox is ready
no entries
Here are the last few lines of the error log:

I am at a loss for what to do now. I have tried these things:
- deleted the printer and reinstalled it
- turned the printer off and on
- stopped and restarted cups
Any ideas? Is this something that has to be fixed at the System Administrator level?
sudo apt-get install gnome-panel
I don't like Unity either -- I use it "Gnome Classic".
