Abstract
Methods, systems, and storage media for outline character printing on a printing device are disclosed. Exemplary implementations may: allocate cache memory of a printing device for registration of an outline character; register outline character data wherein the metadata portion comprises a description of the outline character and the data portion comprises a scanline table for the outline character; receive a print job data at the printing device; determine the print job data identifies the outline character in the cache memory at the printing device; render the scanline table accessed from the cache memory as a pattern of pixels for the outline character for the print job data received; and print, on the printing device, the pattern of pixels rendered from the scanline table accessed from the cache memory for the print job data received.
