Claim 18:
19. A drive waveform determination system comprising:
a liquid ejecting head that includes a drive element and ejects a liquid as a droplet toward a recording medium by driving the drive element; and
a processing circuit that performs processing of determining a waveform of a drive pulse applied to the drive element, wherein
the processing circuit executes
a first acquisition step of acquiring first waveform information regarding a plurality of first waveform candidates of a first drive pulse applied to the drive element to eject a first droplet from the liquid ejecting head toward a recording medium located at a position separated by a first distance from the liquid ejecting head, and acquiring second waveform information regarding a plurality of second waveform candidates of a second drive pulse applied to the drive element to eject a second droplet having a size larger than that of the first droplet from the liquid ejecting head toward the recording medium located at the position separated by the first distance from the liquid ejecting head,
a second acquisition step of acquiring first timing information regarding a first timing, which is a timing at which a flight distance of the droplet from the liquid ejecting head reaches the first distance when each of the plurality of first waveform candidates is used as the waveform of the drive pulse applied to the drive element, and acquiring second timing information regarding a second timing, which is a timing at which the flight distance of the droplet from the liquid ejecting head reaches the first distance when each of the plurality of second waveform candidates is used as the waveform of the drive pulse applied to the drive element, and
a determination step of determining a waveform of each of the first drive pulse and the second drive pulse based on the first timing information and the second timing information.
