1. A system comprising:
a server device that is connected to a first network;
a terminal device that is connected to the first network to communicate with the server device and is connected to a second network that is different from the first network; and
an electronic device that is connected to the second network to communicate with the terminal device, wherein
the server device includes:
a data transmission portion that receives a processing request according to a first protocol from a request source of the processing request, generates data according to a second protocol different from the first protocol, and transmits, to the terminal device, the data according to the second protocol through the first network, the data according to the second protocol including the processing request according to the first protocol; and
a response notification portion that transmits, to the request source of the processing request, response data to the processing request, the response data being transmitted from the terminal device;

the terminal device includes:
a request notification portion that receives the data according to the second protocol transmitted from the server device through the first network, extracts the processing request according to the first protocol from the data according to the second protocol, and transmits the processing request according to the first protocol to the electronic device through the second network; and
a response data transmission portion that transmits, to the server device, the response data transmitted from the electronic device as a response to the processing request; and

the electronic device includes a response portion that receives the processing request according to the first protocol transmitted from the terminal device, processes the processing request according to the first protocol, and transmits, to the terminal device, the response data according to the first protocol as a processing result of the processing request according to the first protocol transmitted from the terminal device.
