3676  Set the DRIVER_INIT info in the tdb. Requires Win32 client code that:
3677
3678  1. Use the driver's config DLL to this UNC printername and:
3679     a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
3680     b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
3681  2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
3682
3683  The last step triggers saving the "driver initialization" information for
3684  this printer into the tdb. Later, new printers that use this driver will
3685  have this initialization information bound to them. This simulates the
3686  driver initialization, as if it had run on the Samba server (as it would
3687  have done on NT).
3688
3689  The Win32 client side code requirement sucks! But until we can run arbitrary
3690  Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
3691  
3692  It would have been easier to use SetPrinter because all the UNMARSHALLING of
3693  the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
3694  about it and you will realize why.  JRR 010720
