Then, the mobile communication terminal 100 transmits an image data file to the printer apparatus 200, and the printer apparatus 200 sends a check response to the mobile communication terminal 100 (fourth step) . Then, the mobile communication terminal 100 transmits the output command of divided screens to the printer apparatus 200, and the printer apparatus 200 sends a check response to the mobile communication terminal 100 (fifth step) . Last, the mobile communication terminal 100 transmits the print output command to the printer apparatus 200, and .the printer apparatus 200 sends a check response to the mobile communication terminal 100 (sixth step) . In this way, the image data stored in the mobile communication terminal 100 are printed through the printer apparatus 200.

The RGB separated BMP format (BMPl) represents an image format in which an R, a G and a B are separated by the page according to the output of the printer apparatus 200. In the JPEG and the BMP, raw data are transmitted to the printer apparatus 200 without a separate processing for data. Herein, the image format and the image size described in the present specification are used only for describing the embodiment of the present invention. Accordingly, the scope of the present invention is not limited to the image format and the image size. FIG. 4 is a diagram illustrating the operation process of an application program stored in the mobile communication terminal according to a preferred embodiment of the present invention, and FIG. 5 is a flow diagram illustrating an application program displayed in the mobile communication terminal according to a preferred embodiment of the present invention. In the following description, it is assumed that the mobile communication terminal 100 includes a camera and image data photographed and/or stored by means of the camera are outputted through the printer apparatus 200 as shown in FIG. 1.

When image data to be printed through the printer apparatus 200 are selected from the displayed list, the application program controls a message "Please check the printer power source and the cable. Start an output" to be displayed as shown in FIG 4b (S504) . That is, in step S504, the application program checks whether or not data communication is possible between the mobile communication terminal 100 and the printer apparatus 200 and checks it through exchange of the command "Devicelnfo" of table 1. In step S504, when the data communication is abnormal between the mobile communication terminal 100 and the printer apparatus 200, that is, when data cable is not normally connected between the mobile communication terminal 100 and the printer apparatus 200 or power is not normally supplied for the mobile communication terminal 100 and the printer apparatus 200, the application program controls an error message to be displayed as shown in FIG 4c (S512) .

That is, after the command "PrintDump" of table 1 is exchanged between the mobile communication terminal 100 and the printer apparatus 200, the image data of the mobile communication terminal 100 are transmitted to the printer apparatus 200 (S506) . In the course of transmitting the image data from the mobile communication terminal 100 to the printer apparatus 200, the application program controls a transmission progress state of the image data to be displayed as shown in FIG 4e. Then, the application program controls a message "Please insert a printing paper" to be displayed as shown in FIG 4f. The application program controls the format of the image data transmitted from the mobile communication terminal 100 to be checked by the printer apparatus 200 by means of the command "KindofImage" of table 1 as shown in FIG 4g, and controls whether or not a printing paper has been normally inserted the printer apparatus 200 to be checked when the check on the format of the image data is ended (S508) . In step s508, when the printing paper has not been normally inserted the printer apparatus 200, the application program controls an error message to be displayed as shown in FIG 4h (S514) . In contrast, when the printing paper has been normally inserted the printer apparatus 200, the application program controls an output progress state to be displayed together with a message reporting the image data are outputting as shown in FIG 4i (S510) . While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment and the drawings, but, on the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims .
