Abstract
A method and apparatus for printing an image on a large surface area or walkway provides for imagewise marking of the surface with a color marking solution, to form a visible image on the surface during an image recording mode of a marking engine. The marking engine includes a scanner and the marking engine moves along the surface and operates the scanner to sense a crude image upon the surface and generates data signals representing the crude image or boundaries defined by the crude image scanned. In response to data signals the marking engine is operated to print an enhanced image of the crude image and/or to color the crude image so that the printing overlies the crude image.
