Abstract: An apparatus for, a method of, and a computer-readable recording medium for controlling printing in a multi function product. If a determination is made that a sub-controller is rendering second printing data when rendering of first printing data is requested and the rendering of the second printing data will take longer than a first predetermined time, a main controller is requested to render the first printing data. If the main controller is idle or will be available within a second predetermined time, the sub-controller provides the first data to the main controller for rendering and the main controller renders the first printing data. If the main controller is not idle and will not be available within the predetermined time, a new determination is made and the process repeats until one of the sub-controller and the main controller renders the first data.

Abstract: A method and apparatus for copying a double-sided document are provided to obtain a double-sided or one-sided copy by using a copying apparatus having a duplex automatic document feeder (DADF), in which an original document is scanned, an odd page image and an even page image of the scanned original document are displayed, an input selecting orientation of the even page image is received, and the odd page and the even page are printed according to the selected orientation. Therefore, when the double-sided or one-sided copy is made from the double-sided original document, the finished copy can be obtained without a reversed even page, thereby eliminating an inconvenience of arranging the page orientation of the finished copy. Further, consumption of paper or a cartridge can be reduced since the finished copy can be obtained without a reversed even page.
