Abstract
A liquid ejecting apparatus performs gradation expression with multiple gradation levels by ejecting liquid droplets onto a medium. In the liquid ejecting apparatus, a period in which a first drive circuit outputs a second drive waveform as a first drive signal at least partially overlaps a period in which a second drive circuit outputs a fourth drive waveform as a second drive signal; a period in which the first drive circuit outputs a third drive waveform as the first drive signal does not overlap the period in which the second drive circuit outputs the fourth drive waveform as the second drive signal; and in a drive cycle, the first drive circuit outputs a first drive waveform as the first drive signal, subsequently outputs the second drive waveform as the first drive signal, and then outputs the third drive waveform as the first drive signal.
