Make sure your printer is selected in the Print window (Windows) or in the Page Setup and Print windows (Mac OS X).
Your document may have more pages than you think. Select Print Preview from your application’s File menu before printing. Then either select to print only the current page, or only those pages with text, or delete the extra pages in your document before printing.
Paper settings in the printer software may be incorrect for your paper size. Check the paper size, orientation, printable area, and layout settings to make sure they’re correct for your paper size.
