How to set color printing?

I have an HP LaserJet CP1525nw printer. It use to print in color but over the past couple of days, it is printing in black and white. I'm printing form Safari.

When I do Command + P, the print dialogue comes up. The small preview there is in color. But I see now way to adjust for color or black/white printing. I do have enough color toner supply. My Windows computer prints color without any issues.

Any ideas how I can access some color printing setting? There isn't any HP printer software installed. Just the Mac OS X printing options.
