The font that can adapt to the screen in Word should be True Type font, and the fonts used in mathematical formulas are mostly special fonts, which are not compatible with printers. So you need to find another way:

My recommendation: You can use the Red Dragonfly Grab Wizard to grab the picture of the interface where Word is located, and then import the picture into Word again before printing.
