Patch to Fix PrintNightmare Vulnerability

Question

In June of 2021, after we installed a patch from MS, users couldn't connect to network printers without having admin right. Per Microsoft, the patch named KB5005625 released on Sept 21, 2021 which was superseded by KB5012647 would fix the issue for good. After we installed the patch KB5012647 this month, we still ran into the same issue where users had to use admin right to install printers. Do I need to do anything else after I install the patch in order to fix the issue for good?
