How to view the print-friendly version of a MediaWiki page?
By default, to be able to view the print-friendly version of a MediaWiki page, click on Printable version located in the toolbox section on the left side of the wiki (assuming the default skin is used).
However, if it is missing, or you don’t want to use it, add this string to the page’s URL:
&printable=yes
and you will see the print-friendly version of the MediaWiki page.
For example, if you wish to view the print-friendly version of:
http://yourdomain.com/wiki/index.php?title=Main_Page
add &printable=yes to the URL so that in your browser the address is:
http://yourdomain.com/wiki/index.php?title=Main_Page&printable=yes
