Canon imagerunner set colour to default to black?

To set a Canon imageRUNNER printer to default to black and white printing, access the printer's settings through the control panel. Navigate to the "Printer Settings" or "Print Preferences" menu, then locate the "Color" options. Change the default setting from "Color" to "Black & White" or "Grayscale." Save the changes to ensure that future print jobs will automatically use black and white as the default.
