Hey @Perkolator, the Square Register will not work with any bluetooth hardware accessory.
You'd be able to connect a USB printer directly to the hub, or a ethernet (or wifi) printer via your network. There aren't currently any other options supported (although it's a huge feature request that the PM team are aware of so sure they're looking into all the options).
Just to link back round to this & want to be more helpful than saying 'no' !
Something like this could help you implement an ethernet printer in the right location:

That will connect to your wifi & create a local ethernet port for the printer.
I've tried using these as they're small & tuck out the way - but didn't find them the most stable connection (although I'm in a van so stuff was getting turned on/off all the time.
