Claim 0:
1. A three-dimensional object printing apparatus comprising:
a liquid discharge head having a nozzle surface on which a plurality of nozzles which discharge a liquid are provided;
a moving mechanism that changes a position and a pose of the liquid discharge head relative to a three-dimensional workpiece; and
a controller a configured to control the moving mechanism and the liquid discharge head in a first printing operating of performing printing,
when the workpiece has a first surface and a second surface that forms a corner bent or curved in a convex shape between the first surface and the second surface, and
when an axis along a scanning direction of the liquid discharge head with respect to the workpiece in the first printing operation of performing printing on the first surface is a first scanning axis and a normal vector of the nozzle surface in the first printing operation is a first discharge vector, the controller is configured to control the moving mechanism to move the liquid discharge head so that the first discharge vector has a component in a direction toward the second surface along the first scanning axis.
