FWIW, here is what I found at the top of a google search of your problem.
"How do I get my HP Officejet Pro 8600 to print black only?

In your software application, click Print.
Select your printer from the list of available printers.
Click the option that opens the Printer Properties dialog box. ...
Click the Features tab, click the Grayscale drop-down menu, and then click Black Ink Only."
