OK...
I'm fairly new with linux and all (though quite experienced with windows) and I've got a very annoying problem.
I recently installed Mandriva ONE on my office PC and, so far, it has been running great (better than XP was in most instances). I picked Mandriva because my fellow employees are very basic computer users.
The problem is in printing: Using OOo 2.0 (though, the problem reoccurs regardless of editor) the printer will print maybe 1 out of 3 tries.
CUPS and the driver were installed automatically when I loaded Mandriva and, as far as I can tell, that stuff seems to be in order. The problem seems to be that the print jobs never completely get queued... it hangs on processing. Sometimes restarting the printer fixes it, sometimes restarting the print server fixes it.
Being a Windows user, I assume this to be a driver issue(?)
It's a Xerox Workcentre M20 - Xerox has a ppd (postscript driver?) available for using this printer with linux, but I'm unsure how to install this.
I'm drawing on your collective knowledges for this one. BTW, I'm not afraid of using the console as long as I'm well advised.

Well, I figured out how to install a PPD driver with CUPS. However, now the printer wont print what I want, but rather prints a detailed list of the commands/codes sent to it (ie: %%grayscale value...) several pages long.
So, back to the generic PCL driver and all of a sudden it doesn't even respond (typically tried PCL 6/XL).
Now I've been trying swapping the USB connection for a parallel (haven't used LPT1 in years!) and end up with the same problems so that can't be it.
Why wouldn't the PPD drivers, developed by Xerox for this printer to work with a Unix system, turn my printed output into command code?

So, I threw in an Ubuntu 6.1 cd, booted into live mode, installed the Xerox WC M20, and came to the same problem: little or no response with a generic PCL driver and nothing but postscript commands using the MFR-supplied PPD.
So, I rephrase my question:

Has anyone out there had any success making a Xerox WorkCentre M20 work with Linux (locally: either USB or LPT)?

Or...

Does anyone out there understand postscript and Xerox printers well enough to help me out?

Maybe I'll post this in the Hardware forums too.
