Given you have WIkidataPageBanner installed (http://mediawiki.org/wiki/Extension:WikidataPageBanner) and are viewing a page with a banner e.g. http://en.wikivoyage.beta.wmflabs.org/wiki/WikidataPageBanner_example_2
Currently banners are not shown in the print view when the reader clicks the browser print (Ctrl + P) function in a modern browser.
The heading should be visible in the printable version
The banner image should not (although that may change in future).
