Click File > Print to see a print preview of the current document to the right of other useful print-related settings.
The right side of the window previews how the document will look when printed. Use the left side of the window to choose a printer or fine-tune settings — for example, to change from Portrait to Landscape, to change the paper size, or to print only the current page.
There are various icons and toolbars that will appear around the document to advance to another page, change the zoom level, and, in Excel, to show the margins so that column width can be changed. To set more print options, click the Page Setup link at the bottom of the left side of the window, below Settings.
