every printer has option to select black or color print. Just select your option. Also some printer print even without color cartridges. Just test it. My HP prints without color cartridges but my brother printer doesn't !
yeah, HP and lexmark can make a black color with color cartridge :lol:
Actually, all do in order to provide more shades a gray, but do you remember the old HP 500 series inkjets that only only had a three color cartridge, and no black?
