Not-printing cells/formulas
 

I have formulas that will result in zero, or no text being displayed.

For instance:
=if(a15,"DISPLAYED","")

When the false value is returned no text is displayed in that cell, but the
cell still prints blank.

So, if I have three pages full of such formulas, they will all print every
time. Short of selecting a print range manually, or setting a print area, is
there a way to set blank cells such as these not to print?
