Connecting your cash drawer to a receipt printer allows the drawer to open automatically when a transaction is completed. 

Here's how to set it up:

What You’ll Need

•     A compatible cash drawer with an RJ11 port

•     A receipt printer with a “DK” (Drawer Kick) port

•     An RJ11 or RJ12 cable (usually included with the drawer)

1. Locate the Ports

•     Receipt Printer: Look for the port labeled “DK”, “Drawer”, or an icon of a cash drawer. This is typically on the back of the printer.

•     Cash Drawer: Find the RJ11 port—usually located underneath or at the rear.

2. Connect the Cable

•     Plug one end of the RJ11 cable into the DK port on the receipt printer.

•     Plug the other end into the RJ11 port on the cash drawer.

3. Configure Printer Settings (Windows)

For Epson or Star Micronics Printers:

•     Go to Devices and Printers

•     Right-click your receipt printer → Printer Properties

•     Navigate to the Device Settings or Peripherals tab

•     Set Peripheral Unit Type to Cash Drawer

•     Choose when the drawer opens:

•     Document Top → opens before printing

•     Document Bottom → opens after printing

•     Click Apply and OK

4. Test the Connection

•     In Printer Properties, go to the General tab

•     Click Print Test Page

•     If configured correctly, the drawer should pop open after the test print
