Abstract
A technique for making multiple copies that includes the steps of scanning a scan region that contains the image to be copied to produce an array of scan region pixel data that contains pixel data for the entire scan region; printing an image based on the array of scan region pixel data; processing the scan region pixel data to determine a subregion of the scan region that contains printable, non-background information; scanning the subregion of the scan region and providing to a print buffer print data only for the subregion of the scan region that contains printable, non-background information; and printing an image based on the subregion print data.
