I recently installed XFCE Community Edition BETA 008 and had some trouble with a HP Laserjet 1020 not printing, although it printed a test page after the initial OS install, it then wouldn't print. CUPS said the test page had printed though.
The above driver compile/install solution didn't solve it, but it was good to have the latest version of the driver, also there is a forum
http://foo2zjs.rkkda.com/forum/ (specifically for the driver) if you need more help.
SOLUTION: I moved the printer to a different USB port, and a test page worked again.
Firefox printed,
GPicView printed after I set it up, but
Mousepad didn't print. After more searching I found out I had to add a package to get mousepad to print. The package is
a2ps, the "GNU a2ps - 'Anything to PostScript' converter and pretty-printer."
I have no idea why the thing stopped printing, I tried rebooting, I tried turning it off, I tried restarting CUPS.
