Printing woes

[Roger Oberholtzer]

What are you trying to print, and with which command? I have found that 
when ghostscript cannot parse a file, it will silently not print. And,
CUPS is using ghostscript to convert at least PostScript to your printer's
format.

Have you tried printing a test page? From the http://localhost:631
interface?

Is the USB handle in /proc/bus/usb/XXX for the printer read/write by
whoever is running the printer software? It is usually only writable by
root. Maybe the CUPS daemon is run by root, but what about individual
pring jobs?
