Abstract: A network image forming apparatus connectable to at least one host apparatus and a method of controlling printing thereof, including receiving a user defined color table generated using at least one host apparatus, and storing the received user defined color table in the network image forming apparatus such that the received user defined color table can be shared by more than one host apparatus connected to the network image forming apparatus, and performing a printing job using the stored user defined color table.

Abstract: A system and a method of adjusting colors of print data are provided. The system includes a printer driver converting a document transmitted from an application program into print data suitable for a printer and transmitting the print data to the printer. A soft proofing unit applies a soft proofing process to the print data converted by the printer driver. A display unit displays the print data obtained through the soft proofing process. A color lookup table (CLUT) supplies a color adjustment value to the print data when the print data is processed in the soft proofing unit. A system and a method of adjusting colors of print data is also provided to allow a user to accurately predict and adjust the colors of a printout, thereby obtaining the printout having the desired colors.

Abstract: A method of providing a print preview of a print document allows a user to preview the print document on a user interface (or a registration window) of a printer driver, thereby allowing the user to intuitively recognize a print preview function and execute the print preview function without being confused by menus associated with the print preview function. The method includes selecting a print menu in an application program related to the print document to print the print document. A printer driver is executed to display a print window on a screen of a computer executing the application program when the print menu is selected on the application program. An additional print preview selection message window is displayed on the screen to instruct a user to select whether or not to invoke a print preview window when a confirmation button is pressed in the print window to transmit a print command to a printer.

Abstract: A host device with a text extraction function and a method of extracting a text thereof. The host device having at least one application program with a text extraction function and to execute a certain document, the application program including a user interface part to input a selection signal to select an operation to be executed on an image included in the executed document, a text extraction part to extract a text from the image, and a text process part to execute the selected operation for the extracted text. Therefore, a user can obtain all the text included in the document.

Abstract: Disclosed is a status information management system and method for network-based image-forming apparatuses. The status information management system comprises at least one image-forming apparatus connected to a network, and for printing data transferred through the network; and a web server connected to the image-forming apparatus through the network, and managing operation status information of the image-forming apparatus, wherein the web server creates in advance, lists, and stores a code file corresponding to each operation status of the image-forming apparatus in order to manage the operation status information of the image-forming apparatus. The image-forming apparatus checks its own operation status at predetermined time intervals, searches the web server for a code file corresponding to the operation status, and reads the code file out of the web server. The web server can check the operation status of the image-forming apparatus by checking the code file read out by the image-forming apparatus.
