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.

Abstract: Provided is an operating method of an image forming apparatus, the operating method including broadcasting a plurality of packets comprising identification information of the image forming apparatus; receiving a connection request comprising the identification information of the image forming apparatus from a mobile terminal which received some packets from among the plurality of broadcasted packets; and connecting to the mobile terminal, based on the connection request, wherein the connection request is transmitted from the mobile terminal when received signal strengths of the some packets received by the mobile terminal are equal to or greater than a first threshold value. In this regard, the first threshold value may indicate a received signal strength greater than a minimum received signal strength at which communication with the mobile terminal is available.
