It's not only that the edit button appears in the printing preview, but any css or js that alters within the article page will appear in the printing preview as well, so it's advised to sign out before you start the preview.

The Ctrl+P works fine to me: It doesn't preview the wiki header and above and it doesn't preview pass below "Community content is available under CC-BY-SA unless otherwise noted". It does not preview the rail as well. What browser are you trying to print?
