Abstract
A printer driver enables printing a color loss determination stamp that accurately indicates whether color loss has occurred in every print mode available on a printer. The image data parameter and storage unitof the printer driverstores a plurality of color loss determination bitmap image dataunits used for printing a color loss determination stampcorrelated to each print mode. When a print mode is selected, an image data selection unitselects and prints the color loss determination bitmap image datacorresponding to the print mode. A color loss determination stampthat accurately reflects if color loss has occurred can therefore be printed when printing in any print mode.
