You can disable the print dialog from being shown to users. This can be useful if you are giving temporary access to a user or you do not want the user to print to network printers.
This feature will only work in applications which support it! Not all GNOME and third party applications have this feature enabled. These changes will have no effect on applications which do not support this feature.
