First Claim
Patent Images
1. An apparatus for printing graphical information on a surface, the apparatus comprising:
- a print head for printing indicia on the surface;
an image sensor for recording an image of the surface, wherein the recorded image contains a position-coding pattern that identifies a position on the surface; and
a processor for converting the recorded image into a recorded position, wherein the print head prints indicia on the surface based on a comparison of the recorded position with the graphical information to be printed.

Abstract
Systems and methods consistent with the present invention include a printer for printing graphical information on a surface. The printer includes a print head for printing indicia on the surface and an image sensor for recording an image of the surface. The recorded image contains a position-coding pattern that identifies a position on the surface. A processor converts the recorded image into a recorded position, and the print head then prints indicia on the surface based on a comparison of the recorded position with the graphical information to be printed.

20. A system for printing graphic information on a surface having a position-coding pattern thereon, wherein an arbitrary subset of the position coding pattern defines a coordinate position on the surface, the system comprising:
-
a print head for printing indicia on the surface; and
an image sensor for recording an image of the surface, wherein the print head prints indicia on the surface based on a comparison of the graphic information with the coordinate position defined by position-coding pattern in the recorded image. - View Dependent Claims (21)

23. An apparatus for printing graphical information on a surface, the apparatus comprising:
-
a nozzle for dispensing dye on the surface;
an image sensor for recording an image of the surface, wherein the recorded image contains a position-coding pattern that codes a position on the surface; and
a processor for converting the recorded image into a recorded position, wherein the processor determines a predicted position of the nozzle based on the recorded position, and wherein the nozzle dispenses dye on the surface when the predicted position corresponds to a graphics position in the graphical information.

24. An apparatus for printing graphical information on a surface, the apparatus comprising:
-
a print head for printing indicia on the surface;
an image sensor for recording an image of the surface, wherein the recorded image contains a position-coding pattern that codes a position on the surface; and
a processor for converting the recorded image into a recorded position, wherein the processor determines a predicted position of the print head based on the recorded position, and wherein the print head prints the indicia on the surface when the predicted position corresponds to a graphics position in the graphical information.

25. A system for printing graphical information, comprising:
-
a printing surface having a position-coding pattern thereon, wherein an arbitrary subset, having a predetermined size, of the position-coding pattern identifies a unique position on the printing surface; and
a printing unit for printing the graphic information on the printing surface, wherein the printing unit further includes;
a print head for printing indicia on the printing surface; and
an image sensor for recording an image of the arbitrary subset on the printing surface, wherein the print head prints indicia on the surface based on a comparison of the identified unique position on the printing surface with the graphical information to be printed.

27. A hand-held printing device configured to print as the device is moved over a surface upon which is recorded a pattern, the hand-held printing device comprising:
-
a housing configured to be held by a user;
a print head in the housing;
a sensor in the housing for reading the pattern;
a processor for determining, as the housing is moved over the surface, a location on the surface based on the pattern read by the sensor, and for causing the print head to print based upon the determined location.
