Abstract: A smart home service which is capable of providing an environment in which calling a control command for a device is available via a user terminal protocol to control between the device and a user terminal based on different type of protocol and a control method for the same. The smart home service server connecting at least one device operated based on a first protocol to at least one user terminal operated based on a second protocol, includes an application programming interface (API) controller configured to allow a control command for the at least one device to be called via the second protocol of the at least one user terminal; a filter configured to convert the called control command according to the first protocol; and a control command transmitter configured to transmit the control command converted according to the first protocol, to the at least one device.

Abstract: Management server is provided. The management server includes a storage unit to store information about a plurality of client groups, a communication interface unit to receive management device identification information from a management device at remote distance connected to at least one image forming apparatus, a mapping unit to map at least one from among the plurality of client groups with the management device based on the received management device identification information, and a control unit to transmit an activation command to the mapped management device, the activation command directing the management device mapped with the client group to collect the information about the connected image forming apparatus.

Abstract: A host device includes a user interface to receive user information to log in a managing server, a communication interface to transmit the user information to the managing server, a display unit, and a controller that, if login to the managing server is performed, controls the display unit to display information corresponding to an image forming apparatus connected to the host device.

Abstract: An image forming apparatus is provided. The image forming apparatus includes a storage unit which stores information regarding the other image forming apparatuses of the same group as the image forming apparatus and quota information of each user which is shared by the other image forming apparatuses, a controller which, if a job command is input, determines whether to perform a job according to whether the number of copies requested by the job command satisfies the quota information of each user, a function unit which performs the job under control of the controller, a quota information administration unit which updates the quota information of each user stored in the storage unit as the job is performed, and a communication interface which transmits the updated quota information of each user to the other image forming apparatuses.
