Then how can I connect the Square terminal to old printer? The only thing that I need is automatic opening of the drawer when I get a cash transaction.

It depends on the type of printer you have. If it’s a USB printer, it plugs right into the hub. If it’s an Ethernet printer you need to plug it into your router and add it in the settings section of your POS app. 

how do I add it to the settings section of POS app? I don't see the option.. mine is ethernet

Are you unable to see Cash Drawers from Settings > Hardware? What POS device and drawer connection do you have? @armadillowell 

The cash drawer has a RJ11 connection to the Star printer port for "Cash Drwr/ Buzzer.  Error message still says "no USB cash drawer".  This is what Square sent with the Android Register system.

I needed to download the Android file transfer utility. Everything works great.

How did you do this?  download the Android file transfer utility

I’m using Square Register and having the same issue. Thank you.

Hey @bels and welcome to the Community.

I'm not sure what you mean. The Point of Sale app?

Someone had the same issue but was able to rectify it by downloading the Android File Transfer Utility, according to their comment. 

I recently purchased the Square Register with a printer-driven cash drawer. When I test the cash drawer with the printer only, it works. But, when I process cash payments on Square, it doesn't automatically open. It's connected properly. There's only one cable on the cash drawer and I've plugged that into the printer.

Hey @BlackOctoMerch,

Thanks for writing in, and welcome to the seller community 👋

I'm sorry to hear about the frustrating experience with your printer and cash drawer. It sounds like you have a printer driven cash drawer. Here's some troubleshooting steps to try:

• Create an active Printer Station for your receipt printer. Head to Settings > Hardware > Printers > Create Printer Station if you haven't already.

• If you already have an active Printer Station, check that at least one toggle is active under the Print from this device.

• Check that your interface cable is properly connected to both your printer and cash drawer. Try unplugging and reconnecting both sides of the cable and switching which device each side of the interface cable is connected to.

Please let us know how you go!
