Hello Prabin,
What’s happening is that when you deploy printers through Group Policy, they get added but aren’t automatically removed when the computer moves to a new OU. That’s why the list keeps piling up: the old printers stay even though the new OU doesn’t push them. The cleaner way to handle this is to use Group Policy Preferences instead of “Deployed Printers,” because Preferences can replace or delete printers when the policy no longer applies. If you don’t want to reconfigure GPOs, another option is a simple startup script that removes printers not tied to the current OU.
