Did you reboot the laptop? It needs to acquire a new address.
If that doesn't work, try turning off the laptop, OBi202 and router. Then reboot each, waiting 3 minutes between the last one.
If that doesn't work, you need to examine how the printer is hooked up. Is it a wired printer hooked to another PC? If yes, you need to make sure the laptop joins the same network. Is it a wireless printer logged into a network? If yes, same answer. If it's plugged into the other router then it may be more complicated.
