Wifi MacBooks intermittant connectivity to wired Bonjour printers

[Mang]

Hi everyone - last week we updated MRs and MSs to:

MR 31.1.5.1

and

MS 17.1.4

Not sure if it's related, but ever since then our Bonjour printers are randomly offline, online, offline etc.  For example right now I can see 3 of the 20 printers in the building.  All of the printers are wired and on the same VLAN as my MacBook.  Clearing mDNS changes the list of available printers but still doesn't show all of them.  When I take my laptop to another area of our building, that list changes as well.

I have made not configuration changes and rebooted almost all of our devices.  Appreciate any thoughts.

hi @Mang - MR 31.1.6 has fixes for mDNS and bonjour related services - you might give it a try to see if it resolves the issue you're facing.

Thanks, I just did this upgrade so we will see how it goes tomorrow!

Unfortunately upgrading to 31.1.6 didn't help.  There are roughly 35 printers on the subnet that my laptop is on and only 2 or showing up in System Settings > Printers > Add printer (MacOS).  Is it relevant that this problem begins as soon as our 1000 students (and their ipads) are in the building?  Their devices are on a different subnet, however their printer list is hit and miss as well.
