Abstract
A liquid discharge head includes an actuator and a drive circuit. The actuator is configured to expand and contract a pressure chambers. The drive circuit is configured to apply a first drive waveform to cause the actuator to discharge a liquid droplet at a first speed, and then a second drive waveform after the first drive waveform to cause the actuator to discharge a liquid droplet at a second speed slower than the first speed.
