Title: Warning system and warning method

Abstract: When there is a possibility where an undesirable printing result may be caused, a preview image useful for the check of the printing result is displayed, prior to an actual printing, to a user. Prior to the printing an image based on data after an image processing of an image data, it is determined whether or not there is a possibility in which an undesirable printing result may be caused based on the image data and, when it is determined that there is the possibility, a warning message is issued. When it is determined that there is a possibility in which an undesirable printing result may be caused, a printer driver simulates the image processing by the printing apparatus to prepare the data after the image processing. A display apparatus displays, prior to the printing of the image, a preview image based on the data after the image processing.
