I have a test sheet to be used by others. Within some of the cells are True/False results that are used in formulas in other cells. I don't want the True/False cells showing their result when I print. How can I set this?

I have tried white font, that doesn't show on screen but is showing in the print preview.

I know I can put them on another sheet or outside the print area, but I'm still wondering if it can be done as I might want to print it with them showing for a validation copy.
