Abstract: A double-sided printing system is disclosed which can effect double-sided printing of an arbitrary combination of a plurality of documents prepared by a plurality of different applications. A double-sided printing management section of a host computer stores “double-sided printing setting information” (pages to be printed, a printing order, a form of double-sided printing, a paper size for printing and so forth) and instructs a printing job processing section to perform printing data processing so that data may be processed in accordance with the setting information by the printing job processing section. The printing job processing section processes data in accordance with the information received from the double-sided printing management section to synthesize the data into printing data for designated double-sided printing and transmits the synthesized printing data to a printer through a data transfer section. The printer prints the printing data received from the host computer.
