Abstract:
Consistent with disclosed embodiments, systems and methods for optimizing printing of a print job comprising graphics by a printer are presented. In some embodiments, the method calculating optimal granularity for the print job, based on specified resolution and page size; generating at least one trigonometric table with the calculated granularity; determining if a job command in the print job comprises a trigonometric function; and, if so, obtaining at least one trigonometric value from the at least one trigonometric table based on information in the job command. A similar process may be used to optimize printing by reducing the number of distance calculations performed by using sub tables.
