My Canon puma printer is printing black and white photos. How do I change the printer settings? In order to print color pictures instead of black and white you might have to change the settings and deactivate grayscale printing. On the Windows desktop, click 'Start', point to 'Settings', then click 'Printers. On the Main tab, click on the 'Grayscale Printing' check-box to remove the check-mark. Click the 'OK' button to save the setting.
