ABSTRACT:
A liquid ejecting head includes a nozzle formation face with a nozzle; a pressure chamber communicated with the nozzle; and a pressure generator changing pressure in the chamber so as to eject liquid from the nozzle. An adjuster adjusts a distance between the nozzle formation face and the target medium so as to be at least a first distance, and a second distance that is longer than the first distance. A driving signal generator generates a driving signal that includes a first pulse having at least a first expansion element and a first ejecting element, and a second pulse having at least a second expansion element and a second ejecting element. A pulse supplier selectively supplies a pulse to the pressure generator. The pulse supplier selects the first pulse when the distance is the first distance, and selects the second pulse when the distance is the second distance.
