ABSTRACT:
In a serial page printer for printing an image line by line by scanning a printing head, even if a motor for driving a roller for conveying a printing medium is rotated by a predetermined amount, the printing medium is not conveyed by a predetermined amount depending on decentering of the roller, the position of the printing medium, and the like, resulting in a printing error. In order to prevent this, a predetermined position of the roller is brought into contact with each line of a printing medium. For this purpose, an apparatus of the present invention detects that the position of the printing medium and the state of the roller are in a predetermined state. Therefore, a line subjected to printing and the state of the roller have a predetermined relationship on any page, and the printing medium can be conveyed by a predetermined amount for each line by adjusting the rotational amount of the roller for each line in advance.
