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.
