ABSTRACT:
In a data processing apparatus connectable to an information processing terminal via an interface, in a power-consumption reduction mode in which electric power supply to a main control unit for controlling communication with the information processing terminal via the interface is interrupted, a request for communication from the information processing terminal is detected. By supplying the main control unit with electric power in response to the detection, the request for communication from the information processing terminal can be accepted even if the apparatus is set to the power-consumption reduction mode in a waiting state.
