BaseDevModeType: What is difference between the two enumerations?

Question

The BaseDevModeType defines two enumerations:

1. PrinterDefault.
2. UserDefault.

I understand that the devmode base structure is populated based on the enumerations.

But, How are these two devmodes different ?

What examples cases would each of the devmodes be different ?

When you install a printer driver it comes with it's own device defaults. The user can also "override" these defaults to set their own defaults. For example the printer might default to no collation; but the user may want collation on by default for all their print jobs. UserDefault should have the defaults the users has overridden from the device defaults.
