A liquid ejecting head control circuit controls a liquid ejecting head and a switching circuit. The liquid ejecting head control circuit includes a drive signal output circuit, and a switching control circuit. The switching control circuit outputs an ejection control signal defining an amount of a liquid to be ejected from a 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. 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.
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:
