Ink cartridge

Two cartridges (one with black ink, one with colored inks) installed in an inkjet printer

An ink cartridge or inkjet cartridge is a replaceable component of an inkjet printer that contains the ink (and sometimes the print head itself) that is spread on paper during printing.

Each ink cartridge contains one or more partitioned ink reservoirs; certain manufacturers also add  electronic contacts and a chip  that communicates with the printer.
