For those who couldn't be asked to learn how to "Print to File" I assume?
In fairness, save as PDF is more intuitive, but let's not pretend this is anything other than a UI change for functionality that's always been there. A good one, sure, but nothing more.
Print TO file, not print a file. Print TO file is to take a screenshot of a page or document to avoid any interpretation issues later.
To print A file, Android has a generic printer driver and there are more featureful proprietary drivers. I printed a shipping label from my phone over wifi the other day. Very easy to detect and add a printer.
It printed slowly and only printed half the page on the first try, but out of the typical printing experience, that's not too bad.
