Yes, this printer has an RJ45 connection for the Ethernet connection. The RJ45 connection allows you to connect the device directly to your router via a network cable.
Hello
There are 2 models, one with Ethernet and one without.
However, both have USB, and the Ethernet model only has the connection hidden on ONE lid.
With the software and a few settings on the IP, I think you'll be able to do it easily.
Watch the videos on YouTube, the setup is always the same no matter which model.
Yes, you can also operate several receipt printers at the same time - each has its own IP that is assigned when the printer is switched on. Important: all devices must be in the same WLAN.
I work with Lightspeed as a POS system. The connection to the POS system runs via a router which is installed behind the Internet Hub and forms its own network. Integration was very simple - assign a fixed IP - store IP in the POS system and done.
You are right, it is TM-T20III and not TN. And it does have a network interface (rj 45 socket) to connect it to the ethernet. We will ask for a correction of this.
