Abstract
A dot printer receives coded printing information, and expands it into dots in an image memory. When expanding the information into dots, the printing contents of the previous printed document and the new printing document are compared as to their coded information. Only the changed portions therebetween are rewritten in the image memory. As a result, the printing efficiency with respect to multiple documents of the same type in which only small portions thereof change is improved.
