In a terminal system having a printing function for printing additional information about special events, introductions, or advertising to sales receipts issued by a convenience store or kiosk when a purchase is made, or to queuing number tickets issued to customers waiting in a bank, customers can select information of personal interest from a list of advertising information so that the selected information is printed to the receipt or ticket issued by the system. A functional terminal of a POS system having an input device, printer, display, and controller for use in various applications comprises a display for presenting plural advertising information entries, a means for selecting desired entries from the displayed list, and a means for printing the selected information to a receipt issued by the terminal device. Information wanted by the customer can thus be selectively printed with the sales transaction information normally printed to the receipt that is handed to the customer.
