printer type (color vs. black&white)?

["Wright, Brian D." <brian wright pw utc com>]

	How can I tell if the user has selected a color printer or a
black&white printer?  I want to call gnome_print_setrgbcolor() only if I am
printing to a color printer.  I called gnome_print_config_dump(), but I
don't see anything that tells me color vs. black&white.
