Claim 4:
5. The drive waveform determination method according to claim 1, wherein
in the first acquisition step, third waveform information regarding a plurality of third waveform candidates of a third drive pulse applied to the drive element to eject the first droplet from the liquid ejecting head toward a recording medium located at a position separated by a second distance longer than the first distance from the liquid ejecting head is acquired, and fourth waveform information regarding a plurality of fourth waveform candidates of a fourth drive pulse applied to the drive element to eject the second droplet from the liquid ejecting head toward the recording medium located at the position separated by the second distance from the liquid ejecting head is acquired,
in the second acquisition step, third timing information regarding a third timing, which is a timing at which the flight distance of the droplet from the liquid ejecting head reaches the second distance when each of the plurality of third waveform candidates is used as the waveform of the drive pulse applied to the drive element is acquired, and fourth timing information regarding a fourth timing, which is a timing at which the flight distance of the droplet from the liquid ejecting head reaches the second distance when each of the plurality of fourth waveform candidates is used as the waveform of the drive pulse applied to the drive element is acquired, and
in the determination step, a waveform of each of the third drive pulse and the fourth drive pulse is determined based on the third timing information and the fourth timing information.
