Abstract:
1. An image printing apparatus comprising: clock generating means for generating a dot clock as a basis of each pixel forming an image; image printing means for printing a one-line image in a main scanning direction in accordance with image data with reference to the dot clock output from said clock generating means, and for printing a one-page image by repeating, in a sub-scanning direction, the one-line image printing performed in the main scanning direction; and a clock control section which changeably controls a frequency of the dot clock during scanning of one line in the main scanning direction; wherein said clock control section controls a number of pixels of one line in the main scanning direction in a case in which the frequency of the dot clock is changed during scanning of the one line to be equal to a number of pixels of one line in the main scanning direction in a case in which the frequency of the dot clock is not changed during scanning of the one line.
