摘要： A device to discharge liquid includes a liquid discharging head to discharge the liquid and a drive waveform generating device to generate and output a drive waveform including continuous multiple drive pulses to discharge the liquid from the liquid discharging head that are continuously arranged in chronological order to form a single droplet. The continuous multiple drive pulses include an inflation waveform element to inflate an individual liquid chamber of the liquid discharging head and a contraction waveform element to contract the inflated individual liquid chamber to discharge the liquid. When the wave element between the continuous multiple drive pulses is determined as the holding wave element between pulses, the voltage held by the holding waveform element is higher than the initial voltage of the inflation waveform element of the first drive pulse and the ending voltage of the contraction waveform element of the last drive pulse.
