PRINTING APPARATUS AND PRINT CONTROL METHOD

摘要

A printing apparatus according to an embodiment of this invention inputs print data, generates a driving pulse to cause a plurality of print elements of a printhead to perform a printing operation and generates a print data signal based on the input print data to cause the printhead to print on a print medium. At this time, for example, the signal generation timing is controlled so as to determine, based on a driving pulse width, a generation range of the print data signal so as not to overlap with the leading edge and the trailing edge of the driving pulse. Subsequently, the generated driving pulse and the generated print data signal are transferred to the printhead, and the printhead is driven to print on the print medium.

1. A printing apparatus that prints on a print medium by using a printhead including a plurality of print elements, comprising:
an input unit configured to input print data; a first generation unit configured to generate a driving pulse to cause the plurality of print elements to perform a printing operation; a second generation unit configured to generate a print data signal based on the print data input by the input unit to cause the printhead to print on the print medium; a control unit configured to control a signal generation timing in one of the first generation unit and the second generation unit so as to determine, based on a driving pulse width, a generation range of the print data signal so as not to overlap with a leading edge and a trailing edge of the driving pulse or determine, based on the generation range of the print data signal, the driving pulse width so that the leading edge and the trailing edge of the driving pulse do not overlap with the generation range of the print data signal; and a print unit configured to transfer the driving pulse generated by the first generation unit and the print data signal generated by the second generation unit to the printhead and drive the printhead to print on the print medium.
