Apple AirPrint

[Craig_Sakach1]

We are a small clinic running a C25 controller (09.12.01.0067) with 3825i AP's and our electronic medical system is Apple based and we're using iPad Air's (34). The issue we are having is like many do, our HP printers will show up for a short period of time via AirPrint and then disappear with the only way of getting them back is by restarting the iPad. Having to restart the iPad in the middle of a large patient load is frustrating for the Doctor's and their assistants.

I've got the mDNS/Bonjour Multicast Filter setup (Controller > Network > Topologies) and also have multicasting configured on our SonicWall gateway.

We've tried each of the following to try to resolve the issue of them disappearing but to no avail;
1. Using the AirPrint feature on the printer itself
2. Collobos Presto software
3. Lantronix xPrintServer

On the iPads we've disabled the Privacy > Location Services > System Services > WiFi setting and perform a Reset Network Settings regularly.

Many articles on the web refer to rebooting the router or applying firmware updates which I've rebooted the entire system after making many of the changes above.

At this point I guess I'm at a loss on what to do or try next so I'm asking for any suggestions you may have.

Thanks,
Craig

Hi, I'm not its architect but this solution works near flawlessly for us and we are near 100% Apple. Occasionally a client has to turn their wifi on/off but not very often. Here's the conversation I had with our architect:

Yeah. It looks like old content, but it's actually still accurate.

We use what's called "Wide Area Bonjour," or "unicast DNS-SD." It's conceptually very similar to the more common multicast component, except it works via unicast DNS queries to a central server rather than via troublesome multicast traffic. Macs and iOS devices see our printers with no additional device configuration beyond getting on the network itself.

Sounds like your CUPS solution would help them. Is there a link I could send them - I'm assuming there are one or two that got you started in that direction.
Thanks.

Thanks
