Printer IP address

Hi,
I purchased tsp700ii from UK dealer. Today when I tried to find the config page or ip address of my printer following the instruction of this video https://www.youtube.com/watch?v=jtmouORM3Kc&t=3s but when i follow all the process I got 3 print out but print out mentioning my printers ip was missing.

Is there any way to find out the printer ip address except pressing feed button or is there any mistake i did?

How could I fix this issue? Please suggest
