Abstract

A device for driving an actuator of a liquid ejection head to eject a liquid, includes a first circuit configured to generate one or more base drive waveforms, and a second circuit configured to generate, based on the one or more base drive waveforms, a multi-drop waveform to be input to the actuator to eject one or more drops of the liquid. The multi-drop waveform includes one or more of: a first ejection waveform, a second ejection waveform having lower ejection efficiency than the first ejection waveform, a third ejection waveform that is a part of the first ejection waveform, and a fourth ejection waveform that is a part of the second ejection waveform.
