Abstract: A method of encoding print data performed by a host device is described in which a print request for a compound document is received; objects included in the compound document is classified into predetermined groups based on object attribute information; each of the predetermined groups is compressed according to a preset compression method; and the compressed groups is merged and the merged groups is transmitted to an image forming apparatus.

Abstract: Provided are an image forming apparatus and a method of controlling collated printing in an image forming apparatus. For example, the image forming apparatus comprises an image former, a communicator to receive a print request from a host device; a controller to convert at least one portion of the data received from the host device into print data corresponding to one copy of the printable content by the image former, in response to the print request; and a memory to store the print data. The controller is to, in response to determining that the memory stores the print data, control the image former to print the plurality of copies of the printable content.

Abstract: A method for providing a user interface screen in a device includes receiving a user input for manipulating a user interface of a printer driver installed in the device, determining a type of an input used for the received user input, determining a display style of the user interface corresponding to the determined type of the input, and providing the user interface presented in the determined display style.

Abstract: A user terminal apparatus includes a storage unit to store a hybrid operation system to support a plurality of different types of user interfaces (UIs), a control unit to execute the hybrid operation system, a display unit to selectively display one of the plurality of UIs depending on the execution of the hybrid operation system, an interface unit connected to an image forming apparatus, and an input unit to receive a user command to check status information of the image forming apparatus, wherein the UIs include a first UI that can communicate with the image forming apparatus through a port monitor, and when the user command is input, the control unit stops a function of the port monitor, receives the status information of the image forming apparatus by executing an agent program that is stored in the storage unit, and displays the received status information in the first UI.

Abstract: A method of setting a printing option through a touch input includes displaying a preview, which includes a virtual sheet of paper and thumbnails corresponding to content to be printed, on a touch screen of a mobile device, determining a printing option by receiving and analyzing a touch input on the virtual sheet of paper and the thumbnails, and applying the determined printing option to the preview.

Abstract: A print controlling method, an image forming method and a print controlling terminal apparatus are provided. The print controlling method includes receiving a job command to execute a printing job, determining whether accumulative printing is needed based on a ratio of a number of accumulated organic photo conductor (OPC) revolutions to a number of accumulated output pages of the image forming apparatus, if it is determined that the accumulative printing is needed, accumulating and storing data of the printing job, and, if a number of printing pages of entire data accumulated and stored is greater than or equal to a pre-set threshold number of pages, transmitting all the data to the image forming apparatus.
