I'm posting this question because there is a lot of outdated information on the internet, from the days when Google Cloud Print was the only available option. For folks on WiFi, or printing to an off-site or at-home printer, this worked great. For mobile offices (i.e. in-vehicle printers) that was posing a problem as Bluetooth and USB were not supported.
Since StackExchange has such great SEO, I'm anticipating this post will out-rank the out-dated information that is currently dominant on the internet.
