Abstract

A printing apparatus operating as a liquid ejecting device includes an inkjet head including a plurality of nozzles, a scanning driving unit that causes the inkjet head to perform a main scan, and a control unit. When an abnormal nozzle is present, the control unit causes another nozzle in the vicinity of the abnormal nozzle to eject liquid of a larger amount than at a normal time to some of the ejecting positions where the liquid can be ejected by the other nozzle, the control being performed based on a mask prepared in advance, the mask being data specifying ejecting positions at which the ejection amount of the liquid is increased and ejection amounts to be increased at the ejecting positions so that an amount of liquid to be ejected at the time of the main scanning direction by the other nozzle becomes larger than at the normal time.
