  • Publication number: 20050157329
    Abstract: A system for printing data from a portable terminal including: a portable terminal for storing printable printing data and transmitting data selected by the user to an external device using short-distance wireless communication, when the user's request for printing the data is present; and a wireless printer that receives the selected printing data by the short-distance communication with the portable terminal and prints the received data. In the system, wire cables are not necessary for each piece of equipment and the data transmission time is reduced, because the data of the portable terminal is directly transmitted to the wireless printer and is printed thereby without using an intermediate device such as a PC.
