Abstract: An image forming apparatus and a method of controlling the image forming apparatus are provided. The method includes receiving a reflection signal corresponding to a transmission signal transmitted from the image forming apparatus to a user sensing area, the reflection signal being reflected from a user, determining a distance between the image forming apparatus and the user, based on the received reflection signal, selecting a power consumption mode corresponding to the determined distance from among a plurality of power consumption modes, based on the distance between the image forming apparatus and the user, and performing user authentication or power control according to the selected power consumption mode.

Abstract: An image forming apparatus supporting peer to peer (P2P) connection includes a print engine to perform a print operation; a first wireless interface to connect the image forming apparatus to an access point (AP) of an infrastructured network; a second wireless interface to connect the image forming apparatus to an external mobile device by P2P; a soft AP module to allow the image forming apparatus to perform as an AP when the image forming apparatus is P2P connected; a dynamic host configuration protocol (DHCP) server unit to allocate an internet protocol (IP) address to the mobile device that is P2P connected to the image forming apparatus; a soft AP activating unit to activate the soft AP module; and a control unit. If a discovery packet is received from the mobile device via P2P interface, the control unit is operable to control the image forming apparatus to process the discovery packet.
