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.
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.
So, probably save as PDF, then print PDF.
