Definitely a WIP - I thought I could take a look by changing "0" to "1" on the end of the URL and a page does come up but it's just a template at this stage.
But, print? You must mean printing from browser, a page at a time, because OOTPB manuals have never been officially printable. Would like a PDF version, which would accomplish that purpose, but by keeping it in HTML on the web, they can make changes on the fly and not worry about old PDF versions floating around.
