Image forming apparatus supporting peer-to-peer connection and method of managing channel thereof

A near field communication (NFC) operating mode of an image forming apparatus may be set by determining a type of a job to be performed in the image forming apparatus via NFC tagging of a mobile device, determining a first NFC operating mode corresponding to the determined type of the job from among a plurality of NFC operating modes supported by an NFC module, setting the determined first NFC operating mode as an operating state of the NFC module, and performing the job by tagging the mobile device via NFC by using the set first NFC operating mode.

Image forming apparatus supporting function of near field communication and method of setting NFC operation mode thereof

An image forming apparatus in which connection of an external device and a wireless network is controlled, the image forming apparatus including: a wireless network interface unit to connect the image forming apparatus to a first wireless network or a second wireless network; a user interface unit in which setting a connection configuration to connect the image forming apparatus to the second wireless network according to a request to connect to the second wireless network is performed while the image forming apparatus is connected to the first wireless network; a determining unit to determine whether connection of the second wireless network is terminated after connection of the first wireless network is terminated and the image forming apparatus is connected to the second wireless network according to the set connection configuration; and a controller, as a result of the determining, if connection of the second wireless network is terminated, to control so that the image forming apparatus is connected to a different wireless network from the second wireless network according to the set connection configuration.

Image forming apparatus and method of controlling wireless network connection in the apparatus

A multi-function printer (MFP) supporting Wi-Fi Direct includes a print engine to perform a print operation, a first wireless interface to connect the MFP to an access point (AP) of an infrastructured network, a second wireless interface to Wi-Fi Direct connect the MFP to an external wireless terminal, a soft AP to allow the MFP to perform as an AP when the MFP is Wi-Fi Direct connected, a dynamic host configuration protocol (DHCP) server unit to allocate an internet protocol (IP) address to the wireless device that is Wi-Fi Direct connected to the MFP, a Wi-Fi Direct connection manager to manage the Wi-Fi Direct connection, and an automatic group owner (AGO) manager activate Wi-Fi direct so as to drive the soft AP and operate the MFP as a group owner (GO) when the MFP receives a Wi-Fi Direct activation request.

An application program may be executed through an Internet protocol (IP) address linkage in an image forming apparatus supporting a peer-to-peer connection. The application program may be executed by performing a method which includes connecting the image forming apparatus to a wireless device through a wireless local area network, driving a soft access point (AP) module of the image forming apparatus so that the image forming apparatus functions as an AP, driving a dynamic host configuration protocol server of the image forming apparatus to allocate a dynamic IP address to the connected wireless device, and linking the dynamic IP address allocated to the wireless device with a static IP address that is preset with respect to the wireless device.

Image forming apparatus supporting peer-to-peer connection and method of executing application program thereof through internet protocol address linkage

A method and apparatus for setting up a wireless LAN. The method includes receiving a packet, which informs a user that a WPS (Wi-Fi Protected Setup) button of an access point is operated, from the access point; activating a button provided in an image forming apparatus as a WPS button; selecting a button activated as the WPS button; and if the button activated as the WPS button is selected, establishing a wireless network with the access point.

Using a button provided in an image forming apparatus to start a Wi-Fi protected setup

Provided is a method and apparatus for establishing a wireless connection between devices to enable wireless data communication in a wireless communication network. The method includes: establishing the wireless connection with default wireless setting values; receiving currently set wireless setting values of an external device from the external device; and establishing the wireless connection using the received wireless setting values of the external device. Accordingly, when a user wants to establish a wireless connection between two devices to enable wireless data communication in a wireless communication network, by automatically matching wireless setting values of the two devices to each other using pre-defined default wireless setting values, the inconvenience of a user having to personally match the wireless setting values of the two devices is avoided. In particular, by automatically establishing a wireless connection between a printer server and a printer remote control device, convenience can be provided to a user using a network printer.
