The print dedicated terminal includes a server and a printer, and prints image data sent from a plurality of reception dedicated terminals. The reception-only terminal does not have a billing function and outputs a first receipt on which a fee is printed. The user pays a fee by showing the first receipt to the store clerk at the cashier counter. After payment of the fee, a second receipt on which a barcode indicating order identification information is printed is output from a receipt printer connected to the reception-only terminal. When the user holds the barcode of the second receipt over the barcode reader of the print-dedicated terminal, the barcode scanner of the print-dedicated terminal starts reading by reading the barcode and can receive the printed matter.

  In the conventional image printing system, a dedicated reception terminal for receiving a print order and outputting the first receipt is required separately from the dedicated print terminal. In addition, a receipt printer that outputs the second receipt after payment of the fee has been required. As described above, the conventional image printing system is provided with various devices, and the installation cost is high.

Then, the exchange slip data is acquired from the exchange slip issuance terminal 30 using the portable terminal 10, and the exchange slip data is transmitted to the printing apparatus 20 to start printing. Therefore, it is possible to omit a reception-only terminal that outputs a receipt on which a fee is printed as in the conventional case. Further, by providing a small exchange voucher issuing terminal 30 for transmitting the exchange voucher data to the mobile terminal 10, a receipt printer connected to the reception-only terminal via the network can be omitted. Further, since the printing apparatus 30 starts printing upon receipt of the exchange slip data, a barcode scanner that reads the barcode printed on the receipt is unnecessary.

  Thus, the image printing system according to the present embodiment is easy to operate at low cost.

  In the above-described embodiment, an example in which the printing apparatus 20 creates order form data and transmits the order form data to the mobile terminal 10 has been described. However, the mobile terminal 10 may create order form data. The mobile terminal 10 creates an order ID for the print order and notifies the printing apparatus 20 of it. By creating this order ID using its own terminal ID, the order ID becomes unique. Even when the printing apparatus 20 receives print orders from a plurality of users (mobile terminals 10), each order ID is used. The print order of the person can be specified. Information on the unit price for printing image data may be held by an application program in the mobile terminal 10 or may be notified by the printing apparatus 20.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
