‍How to open the cash drawer on Nex

See how to configure your computer so that your cash drawer opens automatically or with a shortcut on your keyboard.


  • The cash drawer communicates directly with your printer, i.e. this process does not go through Nex. Every document sent to your printer generates a command to open the cash drawer. Then, on every impression made, the drawer will open.
  • For this reason, it is important that your printer has this feature available with an RJ11 port, similar to a telephone.
RJ11 input on printers: Epson TM-T20, Bematech MP4200 TH and Elgin i9, respectively.

1. After connecting the drawer to your printer, through the RJ11 input, it is necessary to configure the option to open the drawer in the printer driver itself. In the printer driver, you can choose to open before or after printing. This way, whenever Nex sends a print command, your printer will open the drawer.
