Abstract
A printer having a digital image processing capability and capable of printing image data on a sheet of irregular size. The printer selects either a regular size sheet print mode or an irregular size sheet print mode. When the irregular size sheet print mode, the printer sequentially scans a sheet of irregular size and a document, calculates a magnification change ratio for the sheet on the basis of the resulting size data, and then prints the image data of the document on the sheet on the basis of the calculated magnification change ratio.
