Hello, im using a Xiaomi AX3600 as dump AP.
My network setup:
FritzBox 7590 as Modem and router.
That is connected to a switch.
On that switch there are a few devices including a HP Color Laserjet MFP M 281fdw and the Xiaomi accesspoint.
The problem is, when im using the wifi of the xiaomi (openwrt), all iphones and ipads cant find the airprint printer. I can access the webinterface of the printer.
Now i turned on the wifi of the fritzbox and connected my phone to that. Now airprint works again.
What settings do i have to change to get airprint working again?
Under normal circumstances, a dumb AP will not affect airprint or other mdns related services.
What physical port on the Xiaomi router is used for the uplink to the FB7590?

Try removing all of the 802.11r related items.

Yes now it works.
Why is roaming the problem?
Some devices just simply don't work well with 802.11r. I don't know the inner workings of why it would cause conflicts with airprint, but I generally avoid 802.11r because of the risk of additional issues... a well tuned environment doesn't really need the additional fast roaming standard in most cases.

I only have one accesspoint.
I just wanted that devices switch between 5 and 2.4 ghz
In that case, 802.11r is not applicable and should be disabled.
This is a client side thing (as is roaming in general)... drop your 5GHz power levels slightly if you need your clients to more aggressively switch to 2.4G.
