A method of performing an image forming operation using user information, the method including receiving domain information of a user and performing user authentication using the received domain information; receiving a request for the image forming operation after successfully performing the user authentication; querying a lightweight directory access protocol (LDAP) server using the domain information used for the user authentication to acquire user information necessary for performing the image forming operation; and performing the image forming operation using the user information acquired by querying the LDAP server.

Method of performing image forming operation using user information and image forming apparatus for performing the method

A semiconductor device, including a substrate having an active region defined therein, a plurality of bit lines extending on the substrate in a first direction, a plurality of interconnection lines extending on the substrate in a second direction, a pad electrically connected to the plurality of interconnection lines and configured to apply an external voltage, a plurality of metal contacts electrically connecting the interconnection lines and the plurality of bit lines, and a plurality of bit line contacts that are in contact with the active region and electrically connect the plurality of bit lines and the active region, wherein a size of at least some of the bit line contacts and/or at least some of the metal contacts vary based on a distance of the respective bit line contact or the metal contact from the pad.

Semiconductor device

A method of managing an image forming apparatus provided with a web server includes receiving a connection request for the web server, determining whether a MAC (Media Access Control) address of a user terminal device that has requested the connection is a pre-stored MAC address, and approving the connection of the user terminal device that has requested the connection to the web server if it is determined that the MAC address of the user terminal device that has requested the connection has been pre-stored.

Image forming apparatus to determine pre-storage of a MAC (media access control) address, management method thereof, and computer readable recording medium

A host apparatus, a device, and a method to setup a folder share service. A controller to control displaying a user interface (UI) screen to select a device using the folder share service and a shared folder, and a UI screen to set permissions of the selected shared folder corresponding to at least one added user account and to set store options of a file to be stored to the shared folder in a display. A first communication portion transmits setup information of the user account to the device.

Host apparatus, image forming apparatus and method to setup folder share service

A method of searching for peripheral image forming apparatuses by using a server that is connected to a host apparatus in which one or more printer application programs (PAP) are installed. The method includes: if a printer management program (PMP) search method is selected as a search method, invoking a PMP installed in the server; receiving from the PMP a search list including one or more image forming apparatuses connectable to the host apparatus; and selecting an image forming apparatus from the search list and connecting the selected image forming apparatus to the host apparatus.

Method of searching for image forming apparatuses by using server, and host apparatus and system for performing the method

A hybrid wired and wireless communication device and a wired and wireless communication method thereof. The wired and wireless communication method includes determining whether a wired communication module has been linked to a wired communication network, setting a wireless communication operating mode of a wireless communication module to an infrastructure mode when it is determined that the wired communication module has not been linked to the wired communication network, and setting the wireless communication operating mode to an ad-hoc mode when it is determined that the wired communication module has been linked to the wired communication network. Therefore, the wireless communication operating mode is automatically set according to whether the wired communication network has been linked to the wired communication module, thereby increasing a user's convenience.
