A method of printing comprising the steps of: (i) operatively positioning a swipe printer relative to a surface and swiping the printer across the surface; (ii) printing, during the swipe, successive parts of a position-coding pattern onto the surface; (iii) printing, during the swipe, successive parts of a graphic image onto the surface, the position-coding pattern and the graphic image being superimposed; (iv) imaging, during the swipe, portions of the surface on which the printhead has printed the parts of the position-coding pattern; (v) determining, during the swipe, absolute positions of the printhead using imaged parts of the position-coding pattern; and (vi) using the absolute positions to control, during the swipe, printing of the position-coding pattern and the graphic image.
