Abstract
A three-dimensional object printing apparatus includes: a liquid discharging head that discharges liquid to a three-dimensional workpiece; a robot that has N movable portions and that changes a relative position of the liquid discharging head with respect to the workpiece, where N is a natural number greater than or equal to 2; and N encoders provided for the N movable portions to measure amounts of operations of the N movable portions, respectively. Correspondence information regarding a correspondence relationship between an output from a first encoder and a time during operation of the robot is stored. The first encoder is one of the N encoders. Discharging operation of the liquid discharging head is controlled based on an output from the first encoder and the correspondence information, while the robot is operated.
