Are Windows clients able to print to server side printers without updating printer drivers?

Question

I have some domain controller pushing server side printers to Windows 10 clients using GPOs. After installing KB5005652 as part of the recent patchday, some users report that they get an UAC dialog when trying to print which needs to either be confirmed or aborted. Reason for that dialog seems to be that some printer drivers for some printers have been updated recently before the patchday for some unknown reason as well. It seems that Windows detects those newer printer drivers and is trying to update existing ones to the new version triggering the UAC now.

Here's the point: What happens to print jobs when aborting that UAC dialog and simply not updating drivers?

Users don't have the necessary admin credentials to update print drivers and shouldn't need to care as well. Would be best if they could simply abort the dialog and keep printing otherwise. In fact, at least some users reported that exactly that worked, while my own tests resulted in error messages that test pages have NOT been printed at all. I was forced to update drivers during my tests.

So, which is the correct and designed behaviour of Windows?

Thanks!
