Claim:
1. A method of printing, via a handheld printer, an image onto a print medium, wherein an electronic version of the image is stored in a memory, the method comprising: determining a first index location, with respect to the image in physical image space, of an index nozzle of the handheld printer, wherein the handheld printer comprises a plurality of nozzles including (i) the index nozzle and (ii) a plurality of secondary nozzles; determining a first rotation angle of the handheld printer; based at least in part on (i) the first index location in the physical image space of the index nozzle and (ii) the first rotation angle, calculating a first secondary location, with respect to the image in the physical image space, of a first secondary nozzle of the plurality of secondary nozzles; based at least in part on (i) the first secondary location in the physical image space of the first secondary nozzle and (ii) the first rotation angle, calculating a second secondary location, with respect to the image in the physical image space, of a second secondary nozzle of the plurality of secondary nozzles; and based at least in part on (i) the second secondary location in the physical image space of the second secondary nozzle and (ii) the first rotation angle, calculating a third secondary location, with respect to the image in the physical image space, of a third secondary nozzle of the plurality of secondary nozzles, wherein the first secondary location in the physical image space, the second secondary location in the physical image space, and the third secondary location in the physical image space form a plurality of secondary locations in the physical image space, and wherein based at least in part on the plurality of secondary locations in the physical image space, one or more selected nozzles of the plurality of nozzles are activated to form at least a portion of the image onto the print medium.
