with a large black cartridge and individual C/M/Y color cartridges. IIRC the black cartridges are about $20 and the colors are about $12 each. They should be easy to refill. And, if the print head gets messed up, you can buy a new print head (separate black and color print heads), unlike Epson.
Other companies are following suit; IIRC newer Xeroxes are similar and some big HP's have individual colors.
