I'm using a Cisco Wireless Controller and I can't find printers from iPads and other iOS devices.  I can print test sheet from xPrintServer itself.  What could cause this problem, and how can I fix it?

The described symptoms indicate that something is blocking Bonjour multicast to port 5353.

First, make sure your router(s) are not blocking Multicast and/or traffic to port 5353. Check your router's documentation or contact the router manufacturer for information on configuring the router to pass Multicast traffic to port 5353.

Then make sure Multicast is enabled on your Cisco Wireless Controller. Here is an article on the Cisco web site on enabling Multicast:
