Fluid discharge device, control method for a fluid discharge device, and a fluid tank

摘要

A fluid discharge device, a control method for a fluid discharge device, and an ink tank enable easy and accurate confirmation of the fluid usage history, such as how much fluid is left in the tank, on the user or device side without increasing the price. An inkjet printer that discharges ink from the inkjet head to print on recording paper has a cartridge loading unit in which a ink cartridge is loaded, an inkjet head that discharges ink drawn from the ink cartridge, a reader/writer that reads and writes an ink usage history about usage of ink in the ink cartridge to an IC chip substrate disposed to the ink cartridge, and a control unit that prints at least a part of the ink usage history written to the IC chip substrate to a printable part on the outside surface of the ink cartridge by the inkjet head.
