Abstract
An embodiment of the present disclosure is a driving circuit for ejecting liquid from a plurality of nozzles in an ejecting section in a liquid ejecting head. The driving circuit includes a first signal generation section that generates a printing driving signal for ejecting the liquid from the nozzles, a second signal generation section that generates an inspection driving signal for inspecting a state of the ejecting section, and a control section that controls the first signal generation section and the second signal generation section so as to exclusively output one of the printing driving signal and the inspection driving signal to the ejecting section.
