Connect the cash drawer to your printer

Your cash drawer should be plugged directly into the back of your printer via an RJ11/RJ12 cable (these look similar to phone cables).

1. Ensure the cable is plugged into the correct port on the receipt printer.
   
   For Epson printers, the cash drawer port is labeled by an image of a cash drawer and the letters DK. Example of cash drawer port on Epson TM-T88 printers:
   
   
   
   For Star Micronics printers, the cash drawer port is usually labelled by the letters DK.
   Example of cash drawer port on Star TSP100 printers:
   
   
   On other printers, the cash drawer port may be labelled differently. Please refer to the printer manual to confirm where the cash drawer port is.
   
   
2. Ensure that the other end of the cable is plugged directly into the cash drawer.
