DRIVE WAVEFORM GENERATION DEVICE, DRIVE WAVEFORM GENERATION METHOD AND PROGRAM, LIQUID JETTING DEVICE, AND PRINTING APPARATUS

A drive waveform generated by a processor includes, within one drive period, a jetting pulse group for jetting a liquid droplet from a nozzle, and a voltage swing for preventing the liquid droplet from being jetted from the nozzle, three or more voltage swings are disposed after a first jetting pulse which is a last jetting pulse in the jetting pulse group, a start end of a first voltage swing immediately after the first jetting pulse is disposed at a position separated from a start end of the first jetting pulse by about a resonance pulse period, and a start end of a second voltage swing immediately after the first voltage swing is disposed at a position separated from the start end of the first voltage swing by about a resonance pulse width.
