>your printer does not show up anymore?
My printer does appear in http://localhost:631/printers and stays in the "processing, accepting jobs" state. I try to print a test page, but it just becomes another job that is processing. I checked the /etc/cups/printers.conf and it is there. I did the /etc/init.d/cupsys restart as you suggested, although I didn't change the configuration file, so I wasn't surprised nothing changed.

The printer (using the parallel port) was working normally for a few months until the problem showed up two days ago. The printing of a document doesn't get past the processing phase in the http://localhost:631/jobs. (to be more accurate, the first document is in processing, and all the others are pending. I have already removed all priting jobs and sent new documents, but the same thing happens)

I don't have any classes in http://localhost:631/classes. Is that normal? I read from http://localhost:631/overview.html that "Printer classes are collections of printers"
What do I put in name, location, description? I put the printer name for the name and description, clicked on continue and cups gave me "client-error-not-possible"

What do I do next? I can't find the "add class" help anywhere for acceptable things to fill in.
