I recently installed Ubuntu 8.04 i386 Edition on my grandparents Compaq computer. Everything runs great except the printer. It's a Lexmark X3430. It's recognized by Ubuntu as a 3400 series printer, and seems to have the driver installed. However, whenever I try to print something like a test page I get an error saying _3400_Series printer may not be connected. Is it possible to use this printer in Ubuntu?
