    摘要： A printhead module includes a printhead body, a nozzle plate and one or more piezoelectric actuators. The printhead body includes one or more pumping chambers, where each pumping chamber includes a receiving end to receive a printing liquid from a printing liquid supply and an ejecting end for ejecting the printing liquid from the pumping chamber. The nozzle plate includes one or more nozzles formed through the nozzle plate. Each nozzle can be in fluid communication with a pumping chamber and receive printing liquid from the ejecting end for ejection from the nozzle. The one or more piezoelectric actuators are connected to the nozzle plate. A piezoelectric actuator is positioned over each pumping chamber and includes a piezoelectric material configured to deflect and pressurize the pumping chamber, so as to eject printing liquid from a corresponding nozzle in fluid communication with the ejecting end of the pumping chamber.
