Where/how is the book being printed? Locally? What's powering the printer? How do you ensure that the materials (paper, ink, lubricant, etc.) last all those years? What about binding/collating those pages?

Or is the printing occurring once (since the site is static)?

Ideally the printer would only run a few times, I imagine when the internet finally goes down there's no reason to keep printing new copies of the book.
