Abstract:
1. A printing device, comprising: a head that has a plurality of nozzles; a reversing section for reversing a front surface and a back surface that are facing surfaces of a printing medium facing the head; and a control section for causing the head to execute an ejection operation of forming an image forming dot for printing an image designated as a print target and a flushing dot other than the image forming dot on the facing surface by moving either one of the printing medium and the head so as to relatively change the positions of the printing medium and the head and ejecting liquid from each of the nozzles, wherein the control section calculates a liquid amount of the liquid ejected onto each of the two facing surfaces of the printing medium so as to form the image forming dot, predicts occurrence of warpage due to a curl phenomenon in which warpage of the printing medium occurs in one direction by absorbing the ejected liquid based on the liquid amount, and controls the ejection operation of forming the flushing dot such that a difference in the liquid amounts ejected onto the two facing surfaces is equal to or less than a prescribed amount.
