We distribute printers through GPO and OU Units
we have on printer per OU Unit set to per machine
ie F24 machines 1-15 get printer 1 in that room
F24 machines 1-30 get Printer 2 in that room
F26 machines 1-15 get printer 1 in that room etc
everything works ok and the printer is deployed
but for some reason everyone that logs on is getting every printer from every room throughout the school
any ideas
