摘要:
A liquid ejecting apparatus includes a head in which a first nozzle group, a second nozzle group, and a third nozzle group which have a plurality of nozzles are disposed in a predetermined direction, and that can eject a liquid on a medium, a main scanning unit that scans the head in a main scanning direction, a sub scanning unit that relatively moves between the head and the medium in a sub scanning direction intersecting the main scanning direction; and a control unit. When the liquid is ejected to form a plurality of raster lines on the medium, the control unit maintains fixed values for each total value of a nozzle usage rate of the first nozzle group, total value of a nozzle usage rate of the second nozzle group, and total value of a nozzle usage rate of the third nozzle group, corresponding to the respective raster lines.
