Android chrome print, how is it set up?

I'm looking to replace a mobile laptop with an Android tablet. I noticed on my Android 4 phone, in Chrome, there is an option Menu>Print, which lets me generate a PDF, or select a printer. When I choose "All Printers", it says "Searching for printers", and does not list any. I'm guessing I need to set up a WiFi printer. Or do I need Bluetooth? What should I search for to make sure I get a compatible printer. Also, can this work without an internet connection? (assuming I managed to cache the page or pull up the page in Chrome) I need to be able to print reliable even in spotty internet.
