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. A vehicle supports the marking engine and includes a drive that engages the surface at plural locations and moves the marking engine relative to the surface. The marking engine is located outboard of an area defined by lines connecting the plural locations so that during operation of the marking engine during the image recording mode the drive does not engage areas of the surface that have been previously imagewise marked.
