When the Mac is connected by cable, we can print to the printer that is also connected by cable. When we unplug the cable on our Mac, and connect to the R510 AP with ZoneDirector, we are not able to print.
Between the ZoneDirector and AP's, there is a Cisco switch SG200-08P, 2 layer switch. Zo I have enabled the Bonjour gateway for 2 layer switches. I didn't add bridge services.
