The printhead has a plurality of color channels, each color channel comprising at least one nozzle row extending along the length of said printhead, each nozzle in a color channel ejecting the same colored ink. The photo printer also has means for continuously moving 6″×4″ paper sheets past the printhead and a controller for selecting firing nozzles from each color channel of the printhead.
