1. A print position correcting device comprising:
- a head unit which ejects a liquid onto a print medium being transported on a transport surface;
detectors which detect a position of the print medium being transported;
a transport information calculator which calculates transport information regarding a transport status of the print medium based on the position of the detected print medium;
a movement speed calculator which calculates a movement speed used to move the head unit based on the transport information; and
a controller which moves the head unit in a direction parallel to the transport surface based on the transport information and the movement speed.
