Abstract
A liquid ejecting apparatus includes a first ejector; a common driving signal generator configured to generate a common driving signal having a pressure generation pulse including a first element maintained at a first potential, a second element succeeding the first element and maintained at a second potential different from the first potential, and a third element succeeding the second element and maintained at a third potential different from the second potential; a selection control signal generator configured to generate a selection control signal including a first pulse and a second pulse succeeding the first pulse in a time period corresponding to the second element; and a driving waveform selector configured to supply the second potential of the second element to the pressure generating element of the first ejector at the time of the generation of a pulse selected from the first and second pulses of the selection control signal.
