ABSTRACT:
The method of the present invention generates print data to be supplied to a printing module, which ejects ink to form dots on a printing medium. This method includes a dot data generation step of generating dot data, which represent a dot formation in respective pixels, according to pixel values of given video data with regard to the respective pixels. The dot data generation step includes the step of generating the dot data, such that a dot formation with respect to at least part of the pixel values in a pixel belonging to an end area located on an end of the printing medium is different from the dot formation in a pixel belonging to a middle area located in a middle of the printing medium, so as to prevent adhesion of ink to the printing module.
