Printer and printing control method

摘要

A printer and printing control method for improving throughput by performing efficient smoothing processing. The printer adopting the method monitors print data while it is transmitted from a receiving buffer 25a to a print buffer 25b, analyses the print data by a unit of one scanning area of a printhead whether the print data causes printing operation of the printhead, and, if no print data which causes printing operation is included in the print data corresponding to the one scanning area, controls to skip execution of row-column conversion and/or smoothing processing. <IMAGE>
