A method for designing a second ink-jet cartridge characterized by a datum structure, an ink reservoir system and a printhead structure, given a first cartridge design, wherein the printhead structure of the two cartridges are different. The method uses a common datum structure and ink reservoir system for both the first and second cartridges, to save on development and tooling expenses. The cartridges differ in the shapes or configurations of the headland structures, the flexible interconnect circuits, the nozzle plates, the ink channels or the printhead substrates.
