Abstract

The present invention provides a printing apparatus capable of managing the remaining amount of printing medium contained in a cartridge without the need for additional structures. [Solution] The printing apparatus 1 includes a storage unit that stores an identifier of a cartridge containing a printing medium and the remaining amount of the printing medium in association with each other, a printing unit that prints on the printing medium supplied from the cartridge, and a control unit that controls the printing unit and the storage unit so that when a new identifier not stored in the storage unit is specified, the printing unit prints the new identifier on the printing medium and the storage unit stores the new identifier in association with the remaining amount of the printing medium contained in the cartridge identified by the new identifier.
