METHOD FOR DUPLEX PRINTING IN PRINTING MACHINE HAVING FUNCTION OF DUPLEX PRINTING

摘要

PURPOSE: A method for duplex printing in a printing machine having a function of duplex printing is provided to optimally print pages by variably scheduling the order of the pages to be printed according to various situations. CONSTITUTION: Received print data is made into images by consecutive pages(20). It is inspected whether two pages of images corresponding to both sides exist(22). If so, a dual queue having odd page image information and even page image information is formed(24). The order of the pages to be printed is variably decided by using the dual queue, and duplex printing is executed to a print medium(30-38). In the case that odd and even pages are completely printed, a memory related to the dual queue is released(40-44). It is inspected whether the print data is received(26). It is inspected whether all printing is completed(28).
