Abstract
A drive waveform generation device includes a generation unit that generates a drive waveform having, as each cycle, a first waveform for droplet ejection or a second waveform for vibrating a liquid meniscus by selecting from a first period having a first potential that is lower than a reference potential, a second period following the first period continuously and having a second potential that is higher than or equal to the reference potential, a third period following the second period continuously and having a third potential that is higher than the first potential and lower than the second potential, and a fourth period following the third period continuously and having a fourth potential that is higher than the first potential and lower than the third potential, the first period, the second period, the third period and the fourth period being included in a fundamental waveform as defined herein.
