ABSTRACT:
There are provided a method and apparatus for printing a print image on a print material by using a print head based on dot information of the print image by causing at least one of the print head and the print material to move to thereby effect relative motion between the print head and the print material at a relative speed dependent on a rotational speed of a DC motor as a drive source. Driving of the DC motor and the print head is controlled for printing of the print image. A distance from a predetermined length start position selected from a front end position, a print start position, and a print end position of the print material to a predetermined length end position at which the relative motion is to be terminated, is set to a predetermined length. Braking of the DC motor is controlled by varying a braking load on the DC motor in dependence on the relative speed and the predetermined length so as to terminate the relative motion at the predetermined length end position.
