1. A hand-held printer comprising:
a print module configured for multidirectional hand-held printing and configured to receive image data stored in a memory; a print head in communication with the print module and configured to deposit an image, based on the stored image data, on a medium; a position sensor configured to generate sensor position information corresponding to a position of the hand-held printer, wherein the sensor position information corresponds to a position of the hand-held printer on the medium; an image sensor configured to sample a portion of a most recently deposited image; and an image processing module configured to:
calculate image position information within the stored image data, wherein the image position information corresponds to a position within the stored image data; a position processing module configured to:
compare the sampled portion of the most recently deposited image to the image position in order to verify an accuracy of the sensor position information; andcorrect the sensor position information based on the verified accuracy of the sensor position information; a first nozzle array including a first plurality of nozzles fluidly coupled to a first reservoir; and a second nozzle array including a second plurality of nozzles fluidly coupled to a second reservoir, wherein the first reservoir is configured to store a different color than the second reservoir, wherein the first plurality of nozzles are positioned substantially equidistant from a reference point and the second plurality of nozzles are positioned substantially equidistant from the reference point. |
