The size of a print area may be determined using a hand-held printer including an internal tracking device, such as an optical mouse device. Based on the size of the print area, and one or more user settings, an image to be printed on the print surface by the hand-held printer may be scaled and/or repositioned. The hand-held printer may print the image to a desired size while centering the image or otherwise repositioning it, scaling it to fit within user-defined margins or areas, and the like.
