Systems and methods for printing using a position-coding pattern
First Claim
1. An apparatus for printing graphical information on a surface, the graphical information having a predetermined positional relationship with the surface, the apparatus comprising:
- a chassis;
a printhead movable relative to the chassis for printing the graphical information on the surface;
movement mechanism for moving the printhead relative to the chassis;
an image sensor for recording an image of the surface, wherein the surface contains a position-coding pattern that identifies absolute positions on the surface; and
a processor for determining from the image an absolute position and orientation of the chassis relative to the surface, and for controlling the printhead and movement mechanism to print the graphical information onto the surface according to the predetermined positional relationship.

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.
