ABSTRACT:
Provided is a liquid ejecting apparatus including: pressure generation chambers communicating with nozzle openings for ejecting a liquid; and a liquid ejecting head including pressure generation units which cause pressure variations in the pressure generation chambers, wherein idle nozzles including at least one located adjacent to ejection nozzles in the vicinity of the ejection nozzles are selected according to a liquid ejecting timing from the ejection nozzles for ejecting the liquid from the nozzle openings, the pressure generation unit corresponding to the selected idle nozzles is driven, non-ejection driving for pressurizing the pressure generation chamber communicating with the idle nozzles to a degree not ejecting the liquid is performed, and the non-ejection driving is not performed with respect to the pressure generation unit corresponding to the unselected idle nozzles.
