// Tested on Windows Server 2012 R2. //

ALWAYS add printers with Action set to Create.

NEVER set it to Replace (or set “Remove this item when it is no longer applied”), unless you want:

• All printers with Replace action to be removed and re-created at *every* group policy refresh.
• The default printer to be set to the printer that is at 1 in the Order of the group policy printer preferences at *every* group policy refresh. Even if the user selected one of the other printers from the same GPO as default.
