Abstract
Apparatuses and methods for locating and retrieving image data from a memory and to subsequently control nozzles of a handheld printer during a printing operation are described herein. The novel methods may include initially determining an index location of an index nozzle of a printer with respect to an image in physical image space, a version of the image being stored in a memory, and the printer having a plurality of nozzles including the index nozzle. Then, based at least in part on the determined index location, the novel methods may include calculating one or more secondary locations with respect to the image in the physical image space of one or more secondary nozzles of the plurality of nozzles. Data stored at corresponding locations of the memory may then be read based at least in part on the index and secondary locations in physical image space, the corresponding locations of the memory being associated with the index and secondary locations in physical image space. And, finally, the novel methods may include controlling the nozzles based at least in part on the reading of data at the corresponding locations of the memory to form at least a first portion of the image on a…
