PURPOSE: To conserve the cost of development and tool preparation in the production of a printer. CONSTITUTION: First cartridge constitution 50 is provided to constitute a second ink jet cartridge characterized by a datum structure, an ink sump system and a printing head structure. In this case, the printing head structures of two cartridges are different. The datum structure and the ink sump system common to both of the first and second cartridges are used to allow the cartridges to differ in the shapes or configulations of headland structures, flexible interconnect circuits 72, nozzles plates, ink channels or printing head substrates. |
