Firefox 1.0 won't print

Firefox 1.0 from Suse rpm will not print. When I click Print>>Properties, the print command begins with lpr, as it always has. Now, if I print using lpr, the printer prints out an error message telling me how to enter a GS command line to get it to print. The beginning of the command is "gs -q -sDEVICE=pswrite". This portion is in error because gs says "Unable to open the initial device, quitting".

From the console, the message is same.

I got a list of available devices with gs, then from the GS prompt "devicenames ==". None of my printers are there and neither is pswrite. What is with this change and how to fix? Ed Harrison SuSE 9.1, Kernel 2.6.9-vanilla PolarBar Mailer 1.25a
