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