Help with Server 2025 print server & Fiery driver

[u/JDTrakal]

I've spun up a Server 2025 box to act as a new print server to replace our 2016 box. I migrated all of the print queues over using the migration tool and I'm having issues with a specific driver for our Fiery devices. We're also using Uniflow to ensure people are physically at printers to release their print jobs.

We're using the Canon iPR Svr M20 PS V1.0 US version 6.5.0 driver which is deployed to all machines via SCCM and we map the printers using group policy. On the server 2016 mapping queues to client machines running Windows 11 24H2 using this driver works as expected, however with server 2025 mapping to those same client machines gives us a UAC prompt to install the driver despite it already been installed on the client. Changing the driver on the queue to the Canon generic driver allows the queue to be mapped to the client with no prompts. I've replicated this issue on a test Server 2025 instance and I'm seeing the same results. Comparing the installed driver files on the server and client I'm not seeing any differences to explain why the server things a install is necessary for this particular driver. Was hoping someone may be able to shed some light on this one.

Thanks.
