A high-durability printhead for an ink cartridge printing system. The printhead includes a substrate having ink ejectors (e.g. resistors) thereon and an orifice plate positioned above the substrate. The orifice plate has a top surface, bottom surface, and a plurality of openings therethrough. The orifice plate is optimally produced from a non-metallic organic polymeric composition. To improve the durability, heat-stability, and ink resistance of the printhead, an intermediate layer manufactured from a thermoplastic polyimide is employed between the orifice plate and the ink ejector-containing substrate. This particular system generally improves the structural integrity of the printhead and provides longer cartridge life.
