When a printer is installed on a network, default printer permissions are assigned that allow all users to print, and allow select groups to manage the printer, the documents sent to it, or both. Because the printer is available to all users on the network, you might want to limit access for some users by assigning specific printer permissions. For example, you could give all nonadministrative users in a department the Print permission and give all managers the Print and Manage Documents permissions. In this way, all users and managers can print documents, but managers can also change the print status of any document sent to the printer.
Windows provides three levels of printing security permissions: Print, Manage Printers, and Manage Documents. When multiple permissions are assigned to a group of users, the least restrictive permissions apply. However, when Deny is applied, it takes precedence over any permission. The following is a brief explanation of the types of tasks a user can perform at each permission level.
Full control is also the default level for shares
The user can perform the tasks associated with the Print permission and has complete administrative control of the printer. The user can pause and restart the printer, change spooler settings, share a printer, adjust printer permissions, and change printer properties. By default, the Manage Printers permission is assigned to members of the administrators group.
By default, members of the administrators group have full access, which means that the users are assigned the Print, Manage Documents, and Manage Printers permissions.
If all the accounts are administrator accounts it seems any changes you make won't affect this
Setting limited user accounts for them would
