A management server receives a server instruction inquiry from an image forming apparatus, and transmits a communication switching instruction to the image forming apparatus as a response to the server instruction inquiry, such that the communication switching instruction switches the communication system for communicating with the image forming apparatus to push communication. After push communication has been established by conducting an initial communication with the image forming apparatus according to the communication switching instruction, the management server issues server instructions to the image forming apparatus by push communication. |
