摘要： An ink supply communication path is formed so that one end thereof is arranged outside a region confronting a pressure producing chamber at a region confronting a reservoir chamber; and an ink supply constricted port is arranged at a portion of the ink supply communication path, the portion being remotest from the pressure producing chamber. Since the pressure producing chamber is connected to the ink supply constricted port through the elongated ink supply communication path, a jet flow from the ink supply constricted port grows into a large flow along the ink supply communication path, which in turn allows air bubbles susceptible to stagnation in the vicinity of the ink supply constricted port to be discharged by such large flow.

摘要： A printing method that can suppress drops in voltage due to discharging of piezo elements is achieved. A printing method includes: generating a drive signal for driving a piezo element by selecting, based on print data, either a first original drive signal having a unit signal for defining the start to the end of an operation of causing the piezo element to eject ink by changing a voltage of the piezo element using a first reference voltage as a reference, or a second original drive signal having a unit signal for defining the start to the end of an operation of causing the piezo element to eject ink by changing the voltage of the piezo element using a second reference voltage as a reference; ejecting ink using the piezo element by applying the generated drive signal thereto to charge/discharge the piezo element; and charging the piezo element so that the voltage thereof attains either the first or second reference voltage during a predetermined period during which neither the first nor the second original drive signal is selected.
