[ESP32] how to get data from a 3d printer by wifi?

I have a 3D printer conneted on wifi network, it can send data with gcode like
M81 192.168.1.xxx n
i would like to collect n on a esp32,
what is the way to do please ?
thanks in advance

Look at the ChatSever or TelnetClient example sketches that are part of the Ethernet library. You will also have to know how your 3D printer is sending that information (telnet, UDP, etc.) There are several protocols and you will have to know which one it is.

thanks for these informations, it use tcp/ip protocol.

That is not a communication protocol. Internet protocol suite - Wikipedia
Does it use UDP?
