4514  2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4515
4516  The last step triggers saving the "driver initialization" information for
4517  this printer into the tdb. Later, new printers that use this driver will
4518  have this initialization information bound to them. This simulates the
4519  driver initialization, as if it had run on the Samba server (as it would
4520  have done on NT).
4521
4522  The Win32 client side code requirement sucks! But until we can run arbitrary
4523  Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4524
4525  It would have been easier to use SetPrinter because all the UNMARSHALLING of
4526  the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4527  about it and you will realize why.  JRR 010720
