I think as system administrator, you should be able to setup the printer to only print in B&W - not color. I use an HP DeskJet 810c on Fedora 12. It has a color print cartridge, and a separate black ink catridge. The printer actually prints OK in black and white (maybe grayscale) with an empty color cartridge. It does need the empty color cartridge to be present in the printer. Kind Regards, Keith Roberts
