Abstract
A print job is analyzed to determine what page locations can use optional colors and different image quality increase values of different optional colors at the page locations are calculated. Only one of the optional colors is selected, based on which optional color produces the highest print job image quality increase for all of the page locations of the print job. Each individual page of the print job is evaluated to determine if use of the selected optional color increases image quality of the individual page to identify page exceptions. Instructions to mount a selected replaceable printing module corresponding to the selected optional color are displayed, and the print job is printed using the selected replaceable printing module.
