Claim 0:
1. A liquid ejecting head control circuit that controls a liquid ejecting head including a drive element that is driven based on a drive signal to cause a liquid to be ejected from a nozzle, and a switching circuit that switches whether to supply the drive signal to the drive element, comprising:
a drive signal output circuit that outputs the drive signal; and
a switching control circuit that controls the switching circuit, wherein
the switching control circuit outputs an ejection control signal defining an amount of the liquid to be ejected from the nozzle, a switching timing signal defining switching timing of the switching circuit, and a state selection signal defining a state of the switching circuit in a control period defined by the switching timing signal, and
the state selection signal for a first time period for which the liquid ejecting head is controlled so as to eject the liquid from the nozzle is different from the state selection signal for a second time period for which the liquid ejecting head is controlled so as not to eject the liquid from the nozzle.
