A method and an apparatus for connecting an image forming apparatus with multiple host devices. The method includes: displaying a user interface in which the image forming apparatus and the host devices are arranged; setting an area in the user interface in which the host devices are to be connected to the image forming apparatus; and connecting host devices positioned in the set area to the image forming apparatus.

An image forming method which examines validity of an output object using an ROP, for example, and determines whether the output object is printed in a color mode or in a mono mode, is provided. The method includes detecting an output object having a color value from among output objects constituting a mono page, examining the validity of the detected output object, and outputting the detected output object as a mono object if the output object is determined not to be valid. Accordingly, if a mono image having an RGB value is recognized as a color object but is data not to be output on paper or media, the image is recognized as data which are not necessary to be output using color toner, so that only black toner is used. Accordingly, the printing rate increases, and efficiency of processing a printing is enhanced.

An image forming device and a controlling method thereof, in which the image forming device includes: a customer replaceable unit memory (CRUM) associated with a recording material storage medium to store a color conversion table group including a color conversion table that corresponds to status information of the image forming device, and a controller to determine current status information of the image forming device, to read a target color conversion table from among the color conversion table group according to the determined current status information, and to apply the target color conversion table to perform a printing operation on a document. Therefore, an optimum print quality can be guaranteed according to the determined current status of the image forming device.

A color processing method of an image forming device, and an apparatus using the same. In the image forming device, which prints data in a plurality of colors, the color processing method may include storing a plurality of color tables, each color table containing a reference factor used with color processing of image data of an original document, selecting one of the plurality of color tables, processing a color of the image data of the original document with reference to the selected color table, and converting and outputting the color-processed image data of the original document into a data format readable by the image forming device. Accordingly, a user can change the color representation of the printed image according to a predetermined mode.
