Printing that is probably a very bad idea. :P

Printing it wouldn't work. The code in the PDF relies on JavaScript support within the PDF engine. It only works on Chromium-based browsers at the moment.

I was thinking more of the eldrich evil not meant for this earth that your printer might cough up. I suppose, given the code incompatibility, it still might. Also, wtf? Javascript in PDF? What’s that for?

Apparently JS has been around in Acrobat plugin form since 1996, and added to the PDF spec in 2006. At the time, it was viewed as a way to let users make PDFs more interactive and advanced. Nowadays, of course, I'd think it would be a massive attack surface for the bad guys.
