How to Connect a Cash Drawer

A cash drawer connects to your receipt printer, and is triggered to open automatically when you finish a cash sale.

Most of receipt printers have a special cash drawer connector, usually of RJ11 type. Refer to your receipt printer and cash drawer manuals to make sure they are compatible. As long as they are, and given the receipt printer is supported by Loyverse POS, such cash drawer can be used with Loyverse POS as well.

Before connecting a cash drawer, your printer should be paired with Loyverse POS using the Print Receipts and Bills option in your app settings.

Find the cash drawer socket on your receipt printer.
