Not sure what you mean, but maybe it's something I do all the time. When I am printing something that is only black and white (no color) I tell the printer NOT to print any color. The way to do that is in the printer Options when you start to print the document. On the Print window beside the place where you choose your printer there is usually a printer Properties button. Click on that to adjust printer options, and find the place to choose printing in Black & White only.
This option normally defaults to using color, so you often have to set it every time you print a new document.
