Abstract
The present invention provides a printing apparatus that allows high-speed printing of a high quality image on a printing medium without a variation in the scanning speed of a printing head and a method for printing a high quality image on a printing medium using such a novel printing apparatus. For that purpose, an encoder pulse is generated whenever the printing head shifts its position a predetermined distance and a scanning speed of the printing head is detected from an interval of the encoder pulses. Thus, the amount of deviation with respect to output timing of heat pulses for actuating the printing head in response to the scanning speed can be determined.
