The computer 200a receives the image data by the multicast transmission, and transmits the image data and an image data name by using a printing driver for causing the image forming apparatus 100 to print images. The image forming apparatus 100 receives the image data and the image data name, and designates other computers 200b or the like to execute the reply multicast transmission, based on the history information and the image data name. Then, the image forming apparatus 100 executes the reply multicast transmission of the image data to the designated computers 200b or the like. <P>COPYRIGHT: (C)2008,JPO&INPIT |
