Patent ID: 8417841

Claim:
A communication system, comprising: a host device; a terminal device that can establish a communication connection with the host device; and a peripheral device comprising: a first communication section that can be connected to the host device; and a second communication section that can be connected to the terminal device, wherein: the terminal device comprises a section for transmitting terminal device identification information for identifying the terminal device to the host device as communication destination identification information that allows the peripheral device to identify a communication partner in a case of performing communications via the second communication section; the host device comprises a communication destination identification information transmitting section for transmitting the terminal device identification information for identifying the terminal device to the peripheral device as the communication destination identification information when the host device is connected to the terminal device and connected to the peripheral device via the first communication section; and the peripheral device further comprises a section for establishing a communication connection via the second communication section with the communication partner identified by the communication destination identification information transmitted by the communication destination identification information transmitting section; wherein the peripheral device can be further connected to the host device via the second communication section; and wherein the communication destination identification information transmitting section of the host device transmits host device identification information for identifying the host device to the peripheral device as the communication destination identification information when the host device is connected to the peripheral device via the first communication section without being connected to the terminal device.
