Hallo Heather,

If these cells are on the edge of the screen you could define a print
area that excludes these so they won't be printed.
Another option is to define a name somewhere that you set to true when
you're going to print and to false afterwards. (perhaps by using a
checkbox or toggle button and then you make your formula like this
=IF(Printing=TRUE,"",A1*1.21)
