Original Abstract Submitted
Occurrence of a drawing failure is suppressed. An ink jet printer includes: a nozzle configured to eject ink toward a drawing target object; a storage unit that stores drawing data specifying an ejection timing of the nozzle at each of a plurality of offset positions in a conveyance direction, the ejection timing corresponding to drawing information; an optical movement measurement sensor that receives light from the drawing target object and generates a measurement value related to movement of the drawing target object in the conveyance direction based on the received light; and a drawing control unit that controls ink ejection from the nozzle based on reference position information indicating that a reference position of the drawing target object is at a predetermined position, a current offset position with respect to the reference position based on the measurement value generated by the optical movement measurement sensor, and the drawing data.
