cannot change font color before printing?

Hello,

I would like ot make the font of a cell WHITe so it does not appear on the printed copy. Excel changes the font to WHITE on the screen but the Font is black again on the PrintPreview screen....

Private Sub CommandButton2_Click()
    Range("D13").Select
    ActiveCell.Font.Colorindex = 2
    ActiveSheet.PrintPreview
End Sub
