PHPBB3 pdf printing modification

PHPBB3 comes with a "Print view" for topics that displays the data within the topic in a very clear, purely text-based way. I'd need an easy-install mod that does something similar to this function that: - goes through a selected forum finding every sub-forum, - then finds every topic in every sub-forum, - then every page within that topic - then outputs a pdf in a style similar to the "print view" Basically, look at the "Print view" button in the [login to view URL] page on a default phpbb3 installation - I want that button in [login to view URL] that will print out everything within that forum (iterating through sub-forums when there are sub-forums) into a single pdf.
