Abstract: An inkjet printing head prints an image on a printing medium located at a printing position facing the printing head, by a printing operation in which the printing head ejects ink onto the printing medium, and the printing head is capable of resuming the printing operation after suspension of the printing operation. A supporting unit supports the printing medium on which the image is printed by the printing head, and an adjusting unit is capable of adjusting a facing distance between the printing head and the supporting unit. A control unit controls the adjusting unit so that the facing distance is greater than that during the printing of a printed image, in case the printing operation is resumed and the printed image moves relative to the printing position. The control unit controls the adjusting unit based on the time elapsed between the suspension of the printing operation and the resumption of the printing operation, so that the facing distance is greater as the elapsed time is longer.
