摘要： A mail server includes a forwarding confirmation section which notifies a mobile phone of receipt of an e-mail, and mail and address forwarding sections which send attached data separated and a user ID to a print server, respectively. Each printer is managed by the print server that includes data holding and stored data search sections for storing the attached data and user ID. The printer has an input section from which the user ID is inputted. The print server is notified of the user ID inputted from the printer so as to search for attached data corresponding to the notified user ID and transfer it to the printer for print. It is thus possible to provide a print service system capable of printing out attached data when not recognized by some mobile devices including a mobile phone, by a nearest printer connected with a broadband network, without increasing communications costs.
