Specifically, as shown in the screen of FIG. 7B, the CPU 301 displays a directory in which image data (for example, jpg, pdf, etc.) is stored and determines whether or not a directory has been selected. . If a directory has been selected, the process proceeds to S504, and if not selected, the process returns to S503. Here, it is assumed that the local folder 702 stored on the storage such as the ROM 303 or the storage device 304 of the controller 300 of the portable terminal 30 is selected from the directory shown in FIG.

In step S504, the CPU 301 displays a list of image data stored in the selected folder and determines whether image data has been selected by the user. Specifically, as shown in the screen of FIG. 7C, the CPU 301 displays a list 703 of image data and determines whether or not image data has been selected. If image data is selected, the CPU 301 displays a preview display and print setting screen shown in FIG. 7D, and proceeds to step S505. On the other hand, if no image data has been selected, the process returns to S504.
In step S505, the CPU 301 determines whether printing is instructed by the user. Specifically, the CPU 301 displays a TransferJet print button 704 as shown in the screen of FIG. 7D, and determines whether or not the TransferJet print button 704 has been selected. If printing is instructed, the process proceeds to S506, and if printing is not instructed, the flowchart ends.
