ABSTRACT:
The present invention provides an ink jet printing apparatus and method that can print a high-grade image without being affected by a variation in moving speed of a printing head. To accomplish this, an encoder is used which outputs a pulse each time a printing head and a printing medium are moved a specified amount relative to each other. Driving timings with which ink is ejected from the printing head are adjusted depending on the time interval between the pulses.
