Cash drawers are connected to your receipt printer via an RJ12 connector cable and will open when a cash sale is processed in Retail POS and the receipt is printed. The setup process is specific to the device you use Retail POS on (Windows, Mac, or iPad) and the brand of your printer (Epson or Star).

You must use an RJ12 cable for your cash drawer to work. Other types of cables will not work.
