1. A method comprising: arranging a plurality of images for sequentially printing the arranged plurality of images on a sheet which is fed in a feeding direction; cutting the sheet at a cut position that is behind a finally-printed image from among the arranged plurality of images in the feeding direction, the cut position being determined based on a position of the finally-printed image; detecting an inappropriate region of the fed sheet that is not suited to print; changing the cut position based on the position of the finally-printed image, if the inappropriate region is detected behind the finally-printed image, to be behind the detected inappropriate region; and re-arranging at least one of the arranged plurality of images so as to be behind the detected inappropriate region, if the inappropriate region is detected in advance of the finally-printed image, without changing the cut position based on the position of the finally-printed image.
