[0002]

2. Description of the Related Art Conventionally, when distributing materials to everyone in a video conference or the like, the materials are printed in advance and the print result is sent to a remote place by FAX (facsimile), or a device such as a scanner. Then, the read image was transferred and displayed on a display device such as a display.

FIG. 3 is a block diagram of a conventional system. The material creator determines which AP (application) prints the material, and if it is APn, A
The Pn13 is activated, printing is executed using the printing function of the APn, the desired print result 15 output from the printer device 14 is read by the scanner device 16 or the like, and the read image is read by the APm17 of all the participants. It was displayed in the display area.

[0004]

In the above-mentioned conventional print data display method, the AP that prints the material required by the user is determined and activated, and the result printed by the AP is further scanned by a scanner or the like. However, there is a drawback that the operability of material distribution is poor and the conference efficiency is reduced.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a view showing a file management table in which a file name and an AP (application) in this embodiment are associated with each other.

As shown in FIG. 1, the print data display system of the present invention receives a file name from APa10,
A printer information capture device 1 is provided which causes a related AP that replaces the print function provided in advance with the image file creation function to convert the file into image data and displays the image data in the display area of the APa 10. And the printer information capture device 1
Is a printer that replaces the AP analysis unit 2 that determines the AP associated with the file (material) and the printer driver incorporated in the AP with the printer driver a that has the function of creating an image file. A driver replacement unit 3, an AP activation unit 4 for activating the AP determined by the AP analysis unit 2, and a print code for reading code data output by the AP as print data to an auxiliary storage device (not shown) from the auxiliary storage device. Data reading section 5-1
A code conversion unit 5-2 that converts the print code data into image data, an image file creation unit 5-3 that outputs the image data into a file, and a print end determination unit that monitors whether the printing of the AP is completed. 6, a printer driver re-replacement unit 7 for restoring the replaced printer driver, an image file input unit 8 for reading the created image file, and the input image data AP
The image file display instructing section 9 for instructing display in the display area a10.

Next, the operation of this embodiment will be described with reference to FIGS.

When a file to be captured is selected from the file selection screen of APa 10 (in this case, the printer output image of a file other than APa is intercepted and displayed in the display area of APa) is selected.
The P analysis unit 2 selects the associated AP from the file name by referring to the management table 12 (see FIG. 2). Next, the printer driver replacement unit 3 replaces (rewrites) the printer driver function incorporated in the selected AP with the printer driver a function. Here, the printer driver function is a normal printer print output function, and the printer driver a function is
This is a function to convert printer printout data into image data without printing.

After the replacement, the AP starting unit 4 replaces the replaced A
Start P and let it run. The print code data created by the execution of this AP is read by the print code data reading unit 5-1 of the replaced printer driver a, converted into image data by the code conversion unit 5-2, and the image file creation unit 5-. In step 3, an image data file is created and stored in the auxiliary storage device 11.

Next, the print end judgment unit 6 judges the end of execution of the AP, and if it has ended, the printer driver re-replacement unit 7 restores the printer driver a function to the original printer driver function, and the image file The input unit 8 is activated.
The image file input unit 8 reads the image file from the auxiliary storage device 11, and the image file display instruction unit 9 displays the printed image in the display area of the APa 10.

In this embodiment, the case where the user displays on the display device of his / her own has been described. However, in a video conference with a remote place, it is naturally displayed on the display device of the other party by using the broadcast function or the like. , Information will be shared.

As described in the above embodiments, according to the present invention, it becomes possible to directly display the print information of the file of another AP from the currently executing AP as an image on the display device without printing. .

[0017]

As described above, according to the print data display method of the present invention, the print information of the file of another AP from the currently executing AP is directly displayed as an image on the display device without being printed. As a result, the work load on the user is reduced, and the information providing function in the video conference is improved, so that the efficiency of the conference is improved.
