A print system is capable of processing a print order of image data through a network. The print system includes an information device operable to store image data, and an order reception server connected to the information device through the network. The information device sends print information specifying print content including image data to be printed to the order reception server with which a communication is established prior to a formal placing of a print order. The order reception server, when completing a reception of the print information, recognizes that the print order is completed, provides an order number for identifying the print order, and sends the order number to the information device.
