Anyone experiencing printing issues? Recent MS patch might be causing problems

I am looking at a bunch of printing errors and APM failing to process:

The server-side authentication level policy does not allow the user from address 172.29.1.30 to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application.

Windows EventID is 10036

I suspect the recent KB5005568 -force new DCOM authentication is playing a part. Has anyone noticed anything? It just now popped up as the printserver rarely gets restarted…

Yes, we had difficulties too. Had to switch our networked label printer for receiving tags over to USB while IT got the print server back to normal.

I was able to start using APM again after I switched from Server Printer to Client Printer to Process Payments and capture/email the outgoing disbursement notifications.

I happened to have the APM Printer installed as a local printer on my workstation. When I tried to add the APM Printer on other users systems, I was not able to get around the Elevated Permissions requirements MS recently put on adding Printers. I used my Domain Admin account, and that still wasn’t enough to add the networked “local” printer. I’ll let IT worry about that one…
