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. The print preview of the print document is displayed on the screen when the user invokes the print preview window in the print preview selection message window.
