PROBLEM TO BE SOLVED: To issue a print request from a communication apparatus to another communication apparatus for improving convenience in proxy printing.SOLUTION: A requestor communication apparatus outputs a print request to a proxy communication apparatus which outputs a print instruction to an image forming apparatus. When acceptance of the print request is decided, the proxy communication apparatus outputs a request to the requestor communication apparatus to transmit a print list. The requestor communication apparatus generates the print list to be output to the proxy communication apparatus. The proxy communication apparatus determines whether printing can be executed or not by using the print list. When printing can be executed, the proxy communication apparatus generates a new print list by adding identification information thereof to the print list and outputs it to the image forming apparatus. The proxy communication apparatus acquires print data from the requestor communication apparatus, and transfer it to the image forming apparatus. The image forming apparatus prints an image on a sheet by using the print data. |
