We are using driver profiles to send out defaults for features such as the
duplex unit and tray 3, indicating they are installed. Thing is the
profile shows up correctly on the print manager in iManager, but when the
printer is installed it does not show these features as being installed.

Why isn't the profile on the client machine the same as the server driver
profile as configured in the printer?
