You'll need to be a LOT more precise with your masking than that.
The only place, ironically, where you don't have to be very precise is on the hair. For everywhere else, you'll need to zoom way in, and use your Shift key.
How about a Levels layer, and on the Green channel move the white Input slider to 240, and on the Blue channel move the white Output slider to 180?
Fiddle with those numbers as you see fit, of course.
I urge you to take a screenshot, or a series of screenshots if necessary, of the print settings that are working for you right now. To refer back to if a problem pops up again, you know?
