Airprint printers disappears from list

My organisation has recently changed our wi-fi to Aruba central. We have an issue with airprinting and have not been able to resolve it. When a printer is turned on it advertises itself and the iOS devices can see it. Then after about 1 hour later the printer disappears from the list of printers. I reboot the printer and again it only lasts about one hour. airprint is enabled in the airgroup settings. Has anyone experienced this and how did they resolve it?

Re: Airprint printers disappears from list

If you share the make/model of the printer that might help if someone else is having a similar issue.

 

Is the printer connected via Wi-Fi, or is it wired?

Is the printer on the same Wi-Fi network (SSID) as the AirPrint clients?

Is it all operating in a single subnet / 1 VLAN?

Under the General --> Advanced Settings of the Network configuration what have you set for Broadcast Filtering, Multicast Transmission Optimization and Dynamic Multicast Optimization (DMO)?

Under Services have you enabled AirGroup at all? If so what settings?

It might look like you require AirGroup but it's not always necessary depending on the network topology and broadcast/multicast filtering options selected.
