I can not advise you on what printer to use as the tablet you are running Square on is an unsupported device and I don't know what printers will work with the tablet and the Square software and what issues will arise between the two. I don't want to tell you what works with the iOS or Android services as they may not work with the forked version of Android that Amazon runs on their tablets.
@Agent929 & @omugonza, that printer will not work with Square. And also there are NO Bluetooth printers that are compatible with Square on Android devices. there are very few printers that are compatible with Square in general. Also, Kindle Fire tablets are not supported by Square and could stop functioning at any point with an app update.
