Patent abstract
An apparatus for printing graphical information on a surface. The apparatus comprises: a printhead for printing the graphical information; an image sensor for recording an image of the surface, wherein the recorded image contains a position-coding pattern that identifies an absolute position on the surface; and a processor for converting the recorded image into a recorded absolute position. The printhead prints the graphical information onto the surface based on a comparison of the recorded absolute position and the graphical information to be printed.
