What is the IP No. to connect my Host to my Server
I can not connect the host to the server, as I dont know what the IP No. is.
It is the ip fro the device you installed it on plus :3344 so login on the device and ask it. For linux in terminal use "ip addr" and in windows you could use "ipconfig" in cmd.exe to get it. It is the same as you use in the frontend with your webserver.
server IP is also shown in the printer lcd when connected
