input: [Print Setting] Page Setup [Description] 
output: Brings up your computer's Page Setup options. Adjusting the Paper Size resizes the Print Overlay, which masks out the area of the screen that won’t be included in your printed map. If needed, your map elements automatically move inside the printable area when you adjust the paper size. Printing your map (or saving it as a .pdf) prints the area that is not masked by the Print Overlay.
