1. A method for processing a print page, while detecting, alerting, and avoiding printing of solid black areas in the print page, comprising percentage threshold value specifying step of presenting a GUI to a user by which the user specifies coverage percentage threshold value; and upon the user's specifying printing of a print page, performing detection steps comprising determining page-total black pixels in the print page, which comprises counting black pixels in at least one PDL print object for bitmaps, and calculating total black area of black pen and brush in at least one PDL print object by analyzing at least one PDL print object, to avoid rasterization of a PDL print object thus analyzed in case the user cancels printing of the print page, and to avoid rasterization of a PDL print object thus analyzed in its original form in case the user specifies converting the PDL print object; determining number of total pixels in the print page; determining coverage percentage for the print page, which is a percentage of the page-total black pixels in the print page to the number of total pixels in the print page; upon finding that the coverage percentage for the print page does not exceed the coverage percentage threshold value, printing the print page; upon finding that the coverage percentage for the print page exceeds the coverage percentage threshold value, alerting the user of undesirable and wasteful printing of overly dark print page, and presenting to the user a conversion and preview GUI, which lets the user specify printing the print page, converting the print page, or canceling of printing the print page.
