More Information
Summary:In order to print an image at a high speed without using any large-capacity power supply unit, the image to be printed is segmented into grayscale-specific areas before printing, and the cummulative number of printing elements required to print the respective grayscale-specific areas is counted to predict a necessary power. On the basis of the prediction result, the image is then printed by selecting the highest convey speed from convey speeds at which upper limit powers used and rated average power consumptions are determined. This makes it possible to provide an image printing method and apparatus which can realize high-speed image printing.
