How is the customer doing printing? Is it direct IP printing? Does he have a print server?
FIRST Check your user role to make sure that the printer ports are not being blocked by firewall policies. Use an "allowall" firewall policy to check.
If the user is using the same ip scheme as before and cannot print, you should check his user role to see if it is blocking printer ports because:
- By default Airgroup is enabled
- By Default Airprint is Enabled
Airgroup is only necessary if "Drop Broadcast and Multicast" is enabled on the Virtual AP, or printers are on a different subnet.
