The HP 82 Ink Cartridges are part of a modular ink system that delivers fast printing automatically. HP 82 Ink Cartridges come in one 69-ml size and achieve ultimate photo-quality images in concert with the HP 10 Black Ink Cartridge and the HP 11 Print heads. Smart chips embedded into each of the individual print heads and ink cartridges track print head wear and ink usage, and automatically work with the printer to ensure high-quality prints.
