[wlug] Trouble printing to a Fuji Xerox Workcentre 220

Hi everyone, I've got a swanky new Fuji Xerox Workcentre 220. It's connected to my WinXP laptop via USB, which then shares it over Windows File & Print sharing to my network. For all connected Windows machines (x4) it's working fine. However for my EeePC (1005HA) running Ubuntu NBR 9.10, it won't print at all. There are no specific drivers for it. However the printer suggests that it does "PCL6/PostScript 3 Emulation", and I've tried both the Postscript and the PCL6 & PCL5e drivers. All of these choices make the printer warm up, but none of them actually end up in the printer printing anything. I've trawled the Internet, but may have been looking for the wrong thing. Does anyone have any suggestions? Cheers, - Eric
