How do I print with only one color in my Windows OS setup? To use the monochrome effect with Your Canon photo printer in Windows, access the printing preferences by opening the printer properties (there are different ways to access these based on your Windows version). Then, click the Effects tab. Specify the 'Monochrome Effects' setting. Select the monochrome effects box then click the color of your choice. Then, click 'OK' to apply the setting.
