I have that exact printer, and my problem was I added the printer using the GNOME System -> Personal Settings -> Printers dialog, and it didn't work properly, it was there but never printed.
I then added it using YAST2 -> Hardware -> Printer and then it showed the printer in the top dialog as attached and ready to be configured. I made sure to set it to Postscript compatible, and it works fine.
Luck, and hopefully someone else has the same setup, maybe we can get it figured out. I'd hate to say upgrade to 9.2, but you might check to see if there is anything on the Novell/SUSE site about it too.
