Abstract: A method of processing a printing operation in an image forming apparatus in which a plurality of printing jobs are processed in a single printing job includes generating connection information to unify a plurality of printing jobs, changing the plurality of printing jobs to a single printing job using the connection information, and printing data corresponding to the single printing job.

Abstract: A host apparatus capable of connecting with one or more devices using a wireless universal serial bus (WUSB) and a method of connecting the host apparatus to one or more devices. The method includes receiving a connection request signal for connecting to the host apparatus from one of the devices; and selectively responding to the connection request signal of the device according to preset device information. Accordingly, the host can be selectively connected with the device according to the preset connection option of the device. Hence the device can be connected with the host apparatus only when a user wants, and thus user convenience increases in using and managing the device through the host apparatus in the USB environment.

Abstract: A communication method of a host apparatus capable of connecting with a device by using a Wireless Universal Serial Bus (WUSB) includes operations of receiving a connection request signal from the device to be connected to the host apparatus, according to a determination of whether a request to perform an operation in the device occurs in the host apparatus, selectively responding to the connection request signal to connect the device thereto, and performing data communication with the device to perform the operation. According to the communication method, the host apparatus is connected to the device when the host apparatus uses the device, to improve effective and convenient use of the device.

Abstract: A universal plug and play (UPnP)-based network system and a method of controlling the same. A UPnP device can operate according to a description of each control point (CP) when performing a command, by including the description, which is inherent information of each CP, in a command message transmitted from each CP to the UPnP device and allowing the UPnP device to analyze the command message to obtain the description of the CP. The UPnP-based network system includes a plurality of CPs, each of which stores a CP description, which is inherent characteristic information of each CP, and generates and transmits a command message including the CP description, and a UPnP device which is connected to the plurality of CPs over a network, analyzes the command message received from each CP to perform an operation according to the command message, and analyzes the CP description included in the command message to recognize each CP which transmits the command message.

Abstract: A control point in a UPnP network and a method of registering a preference device thereof eliminate discovery and description operations with respect to a preference in the UPnP network. The control point includes a preference device registration unit to register a device selected among a plurality of devices connected to the network as a preference device, a storage unit to store information on pre-registered preference devices and information on services provided by the preference devices, and a UPnP processing unit to receive and process the corresponding service by using information on the preference device selected among the stored preference devices and the information on the service provided by the preference device if one of the stored preference devices is selected.

Abstract: A method and apparatus to generate extensible hypertext markup language (XHTML) data of a device such that a user can generate print data by editing a layout of digital content in a device.
