Before you print, check your page layout and page setup here.
You're ready to print — but are you? First it's smart to check how your pages are laid out for the printer. Everything you need is on the Page Layout tab. The Page Setup group contains Size (8.5 x 11, A4, and so on), Orientation (landscape and portrait), and Margins.
That's right: Margin settings are easily accessible, on the same level as other commands in this group. Remember how in earlier versions you had to dig deep, going to the File menu, Page setup, and so on? Not any more.
