Claim 9:
10. A driving waveform determining system comprising:
a liquid ejecting head that has a driving element for ejecting a liquid; and
a processing circuit that performs processing of determining a waveform of a driving pulse applied to the driving element, wherein
the processing circuit performs
a first step of measuring, by performing a simulation, ejection characteristics of the liquid from the liquid ejecting head when a waveform candidate is used for the driving pulse;
a second step of measuring, by performing an actual measurement, the ejection characteristics of the liquid from the liquid ejecting head when the waveform candidate is used for the driving pulse;
a third step of determining the waveform of the driving pulse in accordance with a measurement result obtained in the first step and a measurement result obtained in the second step;
a fourth step of evaluating a change in reliability of information obtained by the actual measurement;
a fifth step of evaluating a change in reliability of information obtained by the simulation; and
a sixth step of determining whether to perform the first step or the second step in accordance with an evaluation result obtained in the fourth step and an evaluation result obtained in the fifth step.
