Abstract
There is provided a head driving device for causing a head to discharge droplets. The device includes a drive circuit, a first drive waveform generation circuit, a second drive waveform generation circuit, and a correction circuit. The drive circuit is configured to drive the head based on a plurality of drive waveforms to discharge the droplets. The first drive waveform generation circuit configured to generate a first drive waveform of the plurality of drive waveforms. The second drive waveform generation circuit is configured to generate a second drive waveform of the plurality of drive waveforms. The correction circuit is configured to correct the first drive waveform and the second drive waveform with reference to an intermediate potential.
