In an information-processing device, a controller executes a storage process to store a command program in the memory, and an acquisition process for transmitting a request for a piece of wireless identification information to an external device, which is connected to a wired communication interface, via wired communications using the wired communication interface, and for acquiring the piece of wireless identification information from the external device via wired communications using the wired communication interface as a response to the request. The controller specifies the wireless queue by using the acquired piece of wireless identification information and the correlation information which is registered in the registration process by the OS. The controller executes a setup process to enable the command program to output via the wireless communication interface commands to the external device identified by the acquired piece of wireless identification information by using the wireless queue.
