Check your printer settings like this:
You may not be aware, but your printer could default to color every time you print. That means that it costs 17.5 cents per page instead of 2 cents per page. Change your settings by following the instructions below.
To change your default print color:
From the Start menu, click "Control Panel."
Go to "Devices and Printers"
Double-click on your printer.
Click "Printing Preferences" and change the output color to black.
You can also choose to designate color or black and white with each item printed.
After clicking "Print," click "Printer Properties."
Change the "Output Color" section to "Black." If you do not tell your printer to do this, it will mix all three colors together to make the color black.
