1. A handheld printer comprising:
- at least one navigation sensor for tracking two-dimensional motion of the handheld printer with respect to a printing surface, wherein the two-dimensional motion is defined by a first directional component and a second directional component;
a user interface configured to receive boundary settings to define a print area;
a print head controller configured to adjust the print area to a predetermined size selected based on the boundary settings and configured to generate printing instructions based on the adjusted print area and a position of the handheld printer according to the first directional component and the second directional component; and
a print head configured to print on the printing surface based on the printing instructions.

12. A method comprising:
-
tracking, using data received from at least one sensor of a handheld printer, two-dimensional motion of the handheld printer with respect to a printing surface, wherein the two-dimensional motion is defined by a first directional component and a second directional component; receiving boundary settings, from a user interface of the handheld printer, to define a print area on the printing surface; adjusting, by a print head controller of the handheld printer, the print area to a predetermined size selected based on the boundary settings; and generating printing instructions based on the adjusted print area and a position of the handheld printer calculated, at least in part, from the first directional component and the second directional component. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
