Method of controlling communication system

摘要

In a communication system including an image processing apparatus having a VNC server and a Web client, a terminal device having a VNC viewer and a Web client and an information processing apparatus having a Web server, the Web client of the image processing apparatus establishes a first connection with the Web server of the information processing apparatus, and the Web client of the terminal device establishes a second connection with the Web server of the information processing apparatus. The image processing apparatus transmits screen information of an operation panel of the image processing apparatus to the terminal device via the information processing apparatus, and the VNC viewer of the terminal device displays the screen information on a display unit of the terminal device.
