Print on recycled paper. No need to print anything related to programming on high quality paper. It will cost you about double the price per packs of sheets but we print so rarely it's worth filling all of your printers with them.
Why print anything related to programming at all? What's wrong with opening the PDF on your computer and putting it side-by-side to your IDE? Isn't this more practical anyway? (Full text search, being able to copy & paste, and so on)
Of course you can argue that some people prefer reading on paper over reading on a screen. But that argument would be a strawman: The original commenter said they would print this specifically for the case of a broken internet, meaning their normal behaviour is to read that stuff online, on screen.
As a front-end developer, I very often print my layout to be able to scribble on them to show ideas and features mockups very quickly.
