Abstract
A liquid ejecting apparatus executing a print operation of ejecting liquid to a medium when a print job is input includes nozzles configured to eject liquid, piezoelectric elements corresponding to the nozzles, and driving circuits configured to supply a micro vibration pulse for generating micro vibration in the liquid included in the nozzles without ejection of the liquid from the nozzles to the piezoelectric elements. Strength of the micro vibration generated by the micro vibration pulse varies based on the print job.
