A terminal apparatus may send a first inquiry signal to two or more function executing apparatuses; receive a first response signal from each of the two or more function executing apparatuses; and determine whether the function executing apparatus is a first type of function executing apparatus or a second type of function executing apparatus based on the first response signal. The terminal apparatus may send a second inquiry signal to each first type of function executing apparatus; and receive a second response signal from each first type of function executing apparatus; select a target function executing apparatus, by using at least one of first information and second information. The terminal apparatus may establish a wireless connection with the target function executing apparatus via the wireless interface; and send an executing instruction to the target function executing apparatus.
