Image forming system, image forming apparatus, and recording medium

A mobile terminal capable of communication with at least one image forming apparatus for transmitting waves for short-distance wireless communication includes a detection unit that detects, on the basis of the waves, a connection candidate device that is an image forming apparatus as a connection destination candidate in short-distance wireless communication, and a determination unit that determines a pairing mode of short-distance wireless communication in accordance with the number of connection candidate devices detected. When a single connection candidate device is detected as a connection candidate device, the determination unit determines, as the pairing mode, a first mode that does not involve an authentication operation in which a user of the mobile terminal authenticates a connection destination device for short-distance wireless communication, and when multiple connection candidate devices are detected as connection candidate devices, the determination unit determines a second mode that involves the authentication operation as the pairing mode.
