Abstract
There is provided a method for appropriately coping with a case where a unique portion of a sheet is detected at the time of performing printing on a second surface of the sheet in both-side printing. If the unique portion position end mark is detected and it is determined that it is on the other side surface of the sheet, a length of the unique portion area is calculated. In addition, among images that are already printed by the printing onto the one side surface of the sheet, an image on the one side surface of the sheet corresponding to the calculated unique portion area is detected. Next, a group of the detected image on the one side surface and the image on the other side surface corresponding to the detected image are extracted as reprint data, which is stored in a predetermined memory.
Claims14
A printing apparatus comprising:
- a control unit configured to control printing of images so that a plurality of images are printed on a first surface of a continuous sheet and then a plurality of images are printed on a second surface of the continuous sheet which is a backside of the first surface;
- and
- a specifying unit configured to specify on the continuous sheet a print unsuitable area including unique portion, which is unsuitable for image printing,
- wherein in a case where the specifying unit specifies the print unsuitable area when printing on the second surface, the control unit controls the printing of images so as to print an image for the second surface that is to be printed on the print unsuitable area and so as to reprint an image that has been already printed on the first surface corresponding to the print unsuitable area.
A printing control method comprising:
- controlling printing of images so that a plurality of images are printed on a first surface of a continuous sheet and then a plurality of images are printed on a second surface which is a backside of the first surface;
- and
- in a case where a print unsuitable area including a unique portion, which is unsuitable for image printing, of the continuous sheet is specified when printing on the second surface, controlling printing of an image so as to print an image for the second surface that is to be printed on the print unsuitable area and so as to reprint an image that has been already printed on the first surface corresponding to the print unsuitable area.
