Abstract
A liquid ejecting device includes: a piezoelectric element that is deformed by applying at least one drive waveform among a plurality of drive waveforms to the piezoelectric element, the plurality of drive waveforms including a first drive waveform and a second drive waveform; a cavity that is filled with a liquid and is increased or decreased in internal pressure due to deformation of the piezoelectric element; a nozzle that communicates with the cavity, and ejects the liquid as a liquid droplet; and a selection section that selects at least one drive waveform from the plurality of drive waveforms, the liquid droplet including a first liquid droplet ejected when the first drive waveform has been selected, and a second liquid droplet ejected when the second drive waveform has been selected, an ejection volume of the first liquid droplet being almost equal to an ejection volume of the second liquid droplet.
