Japanese Patent JP7056159

B2

A printing apparatus configured to print an image on a medium includes a head having a first nozzle group configured to discharge a first liquid onto a medium, and a second nozzle group configured to discharge a second liquid acting on the first liquid, a main scanning unit configured to move the head in a main scanning direction, a sub scanning unit configured to move the medium in a sub scanning direction, and a control section configured to control discharging of the first liquid and discharging of the second liquid, and in the printing apparatus, the second nozzle group includes an upstream unit disposed on an upstream side of the first nozzle group in the sub scanning direction, and an overlapping unit located on a downstream side of the upstream unit in the sub scanning direction and disposed to overlap with at least a portion of the first nozzle group as viewed in the main scanning direction, the control section determines, based on liquid volume of the first liquid to be discharged, liquid volume of the second liquid to be discharged, and in a case where the liquid volume determined of the second liquid is equal to or less than a threshold value, the control section makes, of the overlapping unit and the upstream unit, at least the overlapping unit discharge the second liquid.
