A control portion receives positional measurement data about the position of the roll sheet along the width direction thereof from the sheet position sensor and controls at least one of start time of image-forming operation in the printer and an image-writing position of the printer by settling at least one of the start time of image-forming operation and the image-writing position based on the positional measurement data.

Abstract: A controller controls printing heads to print a page information mark with black ink to perform line flushing. The printing heads each have a plurality of inkjet nozzles for discharging ink being disposed in parallel in a width direction of web paper. Upon printing the mark, when an overlap region is present in which a mark printable region overlaps a line flushing region with ink other than the black ink, the controller performs control to decrease an ink discharge amount per unit area in the overlap region in the mark printable region to be smaller than that in the mark printable region except for the overlap region and the line flushing region. This causes a decreased total ink discharge amount in the overlap region.
