What is the supported Hardware for Firefly Reservations?

For Firefly Reservations Point-of-Sale, any point-of-sale printer will work, as long as it is installed as a printer on the device just like any other printer.

However, the only printer that supports Direct Print (no need to click through dialogs to select a printer and then all when printing a receipt) is the Star brand printers that have WebPRINT capabilities.
