Liquid-discharge recording head
A liquid-discharge recording head includes large nozzles for discharging large liquid drops and medium and small nozzles for discharging medium and small liquid drops that are smaller than the large liquid drops. The large nozzles are arranged on one side of an ink-supply opening and the medium and small nozzles are arranged on the other side of the ink-supply opening. The number of large nozzles is greater than the number of medium and small nozzles, and the liquid-discharge recording head performs high-speed printing using the large nozzles, high-speed photo printing using the medium and small nozzles, and high-quality photo printing using the small nozzles.
