Abstract

The hand-held printer includes a print module configured for multidirectional printing, a print head in communication with the print module. The print head includes a plurality of nozzle arrays and wherein the nozzles in each of the plurality of nozzle are disposed substantially equidistant from a reference point. The hand-held printer further includes a circular cap configured to rotatably cooperate with the print head, wherein the circular cap cooperates with the print head to define a seal when the circular cap is disposed in a closed position.

Claims

1. A hand-held printer comprising:

a communication interface configured to receive image information from an external device;

a print module configured for multidirectional printing and configured to receive the image information from the communication interface;

a print head configured to print the image information on a print medium, the print head in communication with the print module, the print head comprising a plurality of nozzle arrays,

wherein individual nozzles in each of the plurality of nozzle arrays are disposed substantially equidistant from a reference point;

a circular cap configured to rotatably cooperate with the print head to define a seal when the circular cap is in a closed position;

a scanning device disposed at the reference point; and

a sensor pad disposed adjacent to the scanning device when the circular cap is in the closed position.

2. The hand-held printer of claim 1 further comprising a cleaning pad configured to rotatably engage the plurality of nozzle arrays.

3. The hand-held printer of claim 2, wherein the cleaning pad includes a plurality of wipers.

4. The hand-held printer of claim 3 further comprising a plurality of sealing gaskets, wherein each of the plurality of sealing gaskets is disposed adjacent to at least one of the plurality of wipers.

5. The hand-held printer of claim 1 further comprising:

an image processing module configured to process the image information received by the communication interface and provide processed image information to the print module.

6. A hand-held printer configured to print an image, the hand-held printer comprising:

a plurality of concentric print arrays, wherein each of the plurality of concentric print arrays includes a plurality of print nozzles;

a scanning array, the scanning array disposed at a center point and wherein the center point is defined within the plurality of concentric print arrays such that each of the plurality of concentric print arrays is substantially equidistant to the scanning array;

a circular cap configured to rotatably cooperate with the plurality of concentric print arrays; and

a communication interface configured to receive the image from an external device, wherein the circular cap further comprises a cleaning pad configured to rotatably engage each of the plurality of print nozzles within each of the plurality of concentric print arrays, and wherein the cleaning pad further comprises a plurality of wipers and sealing gaskets.

7. The hand-held printer of claim 6 further comprising a locking mechanism configured to secure the circular cap in a closed position.

8. The hand-held printer of claim 7, wherein the locking mechanism and the circular cap cooperate with at least one sealing gasket to establish a low pressure region adjacent to at least one of the plurality of concentric print arrays.

9. The hand-held printer of claim 6 further comprising:

an image processing module configured to process the image received by the communication interface; and

a print module configured to receive processed image from the image processing module and configured to direct the plurality of print nozzles to dispense ink.

10. The hand-held printer of claim 6, further comprising:

a sensor pad disposed adjacent to the scanning array when the circular cap is in a closed position.

11. A hand-held printer comprising:

a print module configured for multidirectional printing;

a print head in communication with the print module, the print head comprising a plurality of nozzle arrays,

wherein individual nozzles in each of the plurality of nozzle arrays are disposed substantially equidistant from a reference point;

a circular cap configured to rotatably cooperate with the print head to define a seal when the circular cap is in a closed position; and

a cleaning pad configured to rotatably engage the plurality of nozzle arrays, wherein the cleaning pad includes a plurality of wipers.

12. The hand-held printer of claim 11 further comprising a scanning device disposed at the reference point.

13. The hand-held printer of claim 12 further comprising a sensor pad disposed adjacent to the scanning device when the circular cap is in a closed position.

14. A hand-held printer configured to print an image, the hand-held printer comprising:

a plurality of concentric print arrays, wherein each of the plurality of concentric print arrays includes a plurality of print nozzles;

a scanning array, the scanning array disposed at a center point and wherein the center point is defined within the plurality of concentric print arrays such that each of the plurality of concentric print arrays is substantially equidistant to the scanning array;

a circular cap configured to rotatably cooperate with the plurality of concentric print arrays;

a communication interface configured to receive the image from an external device; and

a locking mechanism configured to secure the circular cap in a closed position, wherein the locking mechanism and the circular cap cooperate with at least one sealing gasket to establish a low pressure region adjacent to at least one of the plurality of concentric print arrays.

15. The hand-held printer of claim 14, further comprising:

a sensor pad disposed adjacent to the scanning array.

16. The hand-held printer of claim 14, further comprising:

a cleaning pad configured to rotatably engage the plurality of print nozzles.

17. The hand-held printer of claim 16, wherein the cleaning pad includes a plurality of wipers.

18. The hand-held printer of claim 17 further comprising:

a plurality of sealing gaskets, wherein each of the plurality of sealing gaskets is disposed adjacent to at least one of the plurality of wipers.
