It's pretty straightforward you see, I will explain it to you:-
Open Run - CMD
Then Type in - ping "printer IP"
You just pinged your printer
If you don't know how to get you Printer Ip then follow this:_
GoTo C - Windows - System32
and run - cscript prnmngr.vbs -l
Hopefully it should list all the network IP's, if not refer to this post ---
