Abstract
A printing apparatus and method therefor reduces power-source capacity of the apparatus imposing any load on the printing apparatus and varying its printing speed. In parallel to printing operation, the number of print dots is counted by using a counter, and information amount for calculating the scanning period for each scanning is measured by also using a counter. Then, at the completion of each scanning, a print-duty ratio is calculated from the number of print dots and the information amount for calculating the scanning period for each scanning, and a waiting period to delay starting of the next scanning is set, based on the calculated duty ratio.
