Zebra network printers keep going offline after a few labels are printed. The Zebra printers do not like broadcast packets (multicast) on the network. To find out which hosts are sending broadcast packets, run Wireshark and use this filter.
The traffic will be coming from dasHost.exe and being sent to UDP ports 3289, 10004 and 22222.
eth.addr==ff:ff:ff:ff:ff:ff && udp.port==10004
The solution for now is to add an outbound firewall rule on those clients that are sending broadcast packets. Run this in an admin PowerShell:
New-NetFirewallRule -DisplayName "Block dasHost Broadcast" -Program "$env:SystemRoot\System32\dasHost.exe" -Protocol UDP -LocalPort Any -RemotePort 3289,10004,22222 -Action Block -Profile Any -Direction Outbound
