Monochrome, color and photo printers

A monochrome printer can only produce monochrome images, with only shades of a single color. Most printers can produce only two colors, black (ink) and white (no ink). With half-tonning techniques, however, such a printer can produce acceptable grey-scale images too

A color printer can produce images of multiple colors. A photo printer is a color printer that can produce images that mimic the color range (gamut) and resolution of prints made from photographic film.
