When you want to preview a document as it will be printed, use Word's flexible Print Preview feature. To display it, click the Print Preview button on the Standard toolbar.
You can perform many tasks in Print Preview, including viewing, editing, and printing. But first, here are the basics. Figure 6.17 shows the Print Preview screen. You can see a miniature version of your current document, as well as a toolbar containing several useful options. Whenever you're ready to leave Print Preview, click Close, and Word returns you to the view of the document you were using before you selected Print Preview.
