Opening the cash drawer
You can open the cash drawer manually using the included keys, or wirelessly from the iPad. The iPad connects to the cash drawer through the receipt printer, and the cash drawer opens automatically after each sale, or if you tap Go to cart, More actions, Open drawer from the Shopify POS app.
Test the connection to the cash drawer
When you've set up your receipt printer and your cash drawer, you can check that the connection between them is working.
From Shopify POS, tap ≡, and then tap Settings.
Tap Manage connected hardware.
Tap the printer that you want to test.
Tap Test cash drawer. The cash drawer should open.
To avoid common problems, make sure to check the following:
the cash drawer's cable is plugged into the receipt printer
the receipt printer has paper
the receipt printer is properly paired with the iPad or iPhone
you're using the cash drawer cable you received in the hardware package to connect the cash drawer to the printer.
If you tap No Sale on the products and cart screen and the cash drawer doesn't open, then this is likely a problem with the cash drawer cable. Contact our support team.
