The HP No.82 Ink Cartridges are part of a modular ink system that delivers fast printing automatically. HP No 82 Ink Cartridges come in one 69 mL size and achieve ultimate photo-quality images in concert with the HP No. 11 printheads and HP No. 10 Black ink cartridge. "Smart chips" embedded into each of the individual printheads and ink cartridges track printhead wear and ink usage and automatically work with the printer to ensure high quality prints.
