Abstract

A hand-propelled printer/scanner is disclosed for use in updating a project document, such as any diagram, schematic, floor plan, or other document. The project document is updated with revision drawings and/or notes printed by the hand-propelled printer/scanner directly on an existing project document. The hand-propelled printer/scanner is sized for single hand use and is moved about on the project document for printing the revisions and notes. A position module provides absolute position data so that the revisions and notes are printed at the correct locations on the existing document. Use of the hand-propelled printer/scanner allows project documents to be updated on the job site, as an example.

Claims

1. A printer, comprising:

a scanner configured to scan a document including updates and configured to generate update data from the document;

a position module configured to determine position data of the printer in response to movement of the printer on a copy of the document, wherein the position data includes a location and an orientation of the printer; and

a processor configured to generate print data based on the update data and configured to communicate the print data to selectively print the updates at correct locations on the copy of the document according to the position data.

2. The printer of claim 1, further comprising:

a database configured to store the update data, wherein the processor is configured to access the database for the update data according to the position data.

3. The printer of claim 1, further comprising:

a print mechanism configured to receive the print data from the processor and configured to deposit ink according to the print data.

4. The printer of claim 3, wherein the print mechanism comprises a plurality of print nozzles.

5. The printer of claim 4, wherein the scanner is positioned between at least two of the plurality of print nozzles.

6. The printer of claim 1, further comprising:

a wireless interface configured to communicate with a host to receive the update data.

7. The printer of claim 1, wherein the updates include information added to the document comprising instructions, remarks, annotations, or notes.

8. The printer of claim 1 wherein the position module comprises:

a movement module configured to generate movement data in response to movement of the printer, the movement data indicative of the location and the orientation of the printer relative to an origin and an initial orientation;

a first motion sensor and a second motion sensor configured to communicate motion signals to the movement module in response to movement of the printer; and

a position module processor configured to determine the position data based on the movement data.

9. The printer of claim 8, wherein the movement data is based on an angle between a first line and a second line, wherein the first line is defined by the first motion sensor and the second motion sensor at the origin and the initial orientation, and wherein the second line is defined by the first motion sensor and the second motion sensor at the location and the orientation of the printer.

10. A method comprising:

generating update data from updates to a document;

determining position data in response to movement of a printer on a copy of the document, wherein the position data includes a location and an orientation of the printer;

selecting print data based on the update data and the position data; and

communicating the print data to selectively print the updates at correct locations on the copy of the document according to the position data.

11. The method of claim 10, further comprising:

storing the update data in a database; and

accessing the update data from the database according to the position data.

12. The method of claim 10, further comprising:

scanning the document with a scan head mounted on the printer.

13. The method of claim 12, further comprising:

depositing a marking particle from a print head to the copy of the document according to the print data.

14. The method of claim 13, wherein the print head comprises an array of print nozzles.

15. The method of claim 14, wherein the scan head is positioned within the array of print nozzles.

16. The method of claim 10, further comprising:

generating movement data in response to movement of the printer, the movement data indicative of the location and the orientation of the printer relative to an origin and an initial orientation;

communicating motion signals to a movement module in response to movement of the printer; and

determining the position data based on the movement data.

17. A computer readable storage medium having processor executable instructions configured to:

generate update data from a document;

determine position data in response to movement of a printer on a copy of the document, wherein the position data includes a location and an orientation of the printer;

receive print data based on the position data and the update data corresponding to updates made to the document; and

communicate the print data to selectively print the update data at correct locations on the copy of the document according to the position data.

18. The computer readable storage medium of claim 17, the instructions further configured to:

store the update data in a database; and

access the update data from the database according to the position data.

19. The computer readable storage medium of claim 17, to instructions further configured to:

initiate scanning the document with a scan head mounted on the printer; and

initiate deposit of a marking particle from a print head to the copy of the document according to the print data.

20. The computer readable storage medium of claim 19, wherein the print head comprises an array of print nozzles and the scan head is positioned within the array of print nozzles.
