I have iPrint and Duplex capable printers.
I have iPrint profile setting up the printers to Duplex automatically.
(basically the check box for print on both sides is checked for the user)
I have checked on the printer the flag "Enable Auto Driver/Profile Update" and the two duplex setting was applied to the users who have the printer installed.
All works fine, but when some user goes to the printer properties and change the setting to print on one side, the setting remain on this way and I have to change something in the driver/profile with iManager in order to force the setting again.
I need to force the full duplex setting when users log in or when the Print spooler service starts. Are there any way to do it?

Thanks in advance,
