Print the Whole Page

In Category: Printer

There you can make sure that everything will print correctly. If you see that part of the page will be cut off, just click the "Page Setup" button (it looks like a page with a gear on it) or use the keyboard shortcut Alt+U.

You can then change your page layout to landscape. Your browser is, after all, in landscape format, so why not go with the flow. Go down to where it says "Orientation" and click the radio button next to "Landscape".
