What is the difference between 'Preferences' and 'Printing Defaults' on Printer Properties?
Solution 1:
The Printing Preferences found on the General tab (and also right click printer > Printing Preferences) are the current user's personal default printing settings.
The Printing Defaults found on the Advanced tab are for configuring the default settings provided to any new users who connect to the printer. Note that to configure this you need to have the Manage Printers permission on your user account.
