A basic driving waveform which includes a plurality of jet pulses and a non-jet pulse just before the last jet pulse in one recording period is generated. A part of the pulses is removed from the basic driving waveform by maintaining at least the last jet pulse, and a driving signal that is applied to a discharge energy generation element is generated. In the case of using only the last jet pulse among the plurality of jet pulses is used for the jet, a first driving signal that includes the non-jet pulse just before the last jet pulse is generated. In the case of joining the last jet pulse and at least another jet pulse among the plurality of jet pulses to use the pulses for the jet, a second driving signal that is configured to remove the non-jet pulse is generated.
A device for driving a liquid discharge head, which discharges droplets from a nozzle of a liquid discharge head by generating a driving signal for operating a discharge energy generation element that is provided in response to the nozzle and supplying the driving signal to the discharge energy generation element, comprising:
