Power cable
Wait till the BUSY SESSION STATE indicator glows green (It should take approximately 2 minutes), and then restart the printing device.
After it is connected, the terminal automatically sets up communication with the device. This setup can take a few minutes and after it is done, you need to restart the printing device.
Use cable holders to keep the cables organized and maintain a neat and tidy appearance on the printing device.
