摘要： A drive controller includes circuitry. The circuitry generates multiple types of drive pulses to be applied to a driver of a liquid discharge head including a valve to open and close a discharge port, and applies the multiple types of drive pulses to the driver to cause the driver to move the valve to open and close the discharge port. Each of the multiple types of drive pulses causes the valve to move away from the discharge port at a valve-opening speed to open the discharge port, keep opening the discharge port for an open time, and move toward the discharge port at a valve-closing speed to close the discharge port. Further, the circuitry generates the multiple types of drive pulses, the open time and the valve-closing speed of which are different, and changes the valve-closing speed according to the open time.
