If you will be confirming Brandibble orders on a tablet, we do not recommend using a receipt or thermal printer. These are hard to set up with anything other than a computer so you're best off just purchasing a basic desktop printer, something you can get at Staples or Amazon for about $100. There are several options and something simple will suit you well.
If you will be confirming Brandibble orders on a computer, there are a few receipt / thermal printers we recommend listed below, along with links to the driver download pages for each brand. Make sure you download the appropriate driver based on the computer you're using to send orders to the printer.
