Perhaps a picture will help? Disconnect existing eth0 cable from printer

That looks interesting. Thanks.

I've read that a common printer:IP = 192.168.0.9100 [or something]
Does it mess their network if I just unplug their eth0->printer,
and plug rPi to do: ping common Printer IP/s and save results ?

That was listed in OP. Think from 1st principles; not ito *YOUR* office.
