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
