This is a Continuation Application of prior application Ser. No. 13/712,256, filed on Dec. 12, 2012, which claims priority under 35 U.S.C. §120 from U.S. Provisional Patent Application No. 61/569,391, filed on Dec. 12, 2011, in the U.S. Patent and Trademark Office, the disclosure of which is incorporated herein in its entirety by reference.
The WLAN interface unit 810 is hardware to perform an IEEE 802.11 b/g/n function, and may communicate with a main board, on which the CPU 830 is mounted, of the MFP via a universal serial bus (USB). The Ethernet interface unit 820 is hardware to perform wired Ethernet communication according to IEEE 802.3. The CPU 830 controls overall operations of the MFP The memory unit 840 stores information that controls the MFP and the print data that is to be read. The user interface unit 850 functions as a medium to allow the user to identify information of the MFP and to input commands into the MFP. The user interface unit 850 may be variously modified according to products, for example, may be configured as two or four lines displayed on a display unit such as an LCD or a light emitting diode (LED), or may be a graphic user interface (GUI) so as to represent various graphics. The scanner module 860, the fax module 870, and the print engine 880 are hardware to perform functions of a scanner, a facsimile, and a printer.
The WLAN interface unit 810 allows the MFP to achieve infrastructured network connection and Wi-Fi Direct connection at the same time. The IP address management unit 835 manages an IP address of an infrastructured network interface and an IP address of a Wi-Fi Direct interface. Since the MFP supports a concurrent connection function as described above, if infrastructured network connection and Wi-Fi Direct connection are achieved at the same time according to the concurrent connection function, the MFP has different IP addresses according to the respective interfaces. The IP address management unit 835 checks and provides the IP address of each interface to the control unit 836. The control unit 836 receives the IP address from the IP address management unit 835 and controls an image forming operation requested by an external wireless device. In more detail, if a discovery packet is received via the Wi-Fi Direct interface from a wireless device Wi-Fi Direct connected to the MFP, the control unit 836 receives the IP address of the Wi-Fi Direct interface from the IP address management unit 835, and generates and transmits a response packet including the IP address to the wireless device. The discovery packet may be sent to any apparatuses or devices that are Wi-Fi Direct connected and are in range of the external wireless device. As such, the discovery packet alerts the in-range Wi-Fi Direct connected apparatuses or devices that the external wireless device is in range and is requesting information regarding operations that each of the apparatuses or devices can perform. The wireless device may obtain the IP address of the Wi-Fi Direct interface of the MFP by analyzing the response packet received from the MFP. Also, the control unit 836 may generate the response packet to further include information on services and/or operations providable by the MFP and, in this case, the wireless device may obtain the information on the services and/or operations providable by the MFP by analyzing the response packet.
