4607 Set the DRIVER_INIT info in the tdb. Requires Win32 client code that:
4609 1. Use the driver's config DLL to this UNC printername and:
4610 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4611 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4612 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4614 The last step triggers saving the "driver initialization" information for
4615 this printer into the tdb. Later, new printers that use this driver will
4616 have this initialization information bound to them. This simulates the
4617 driver initialization, as if it had run on the Samba server (as it would
4618 have done on NT).
4620 The Win32 client side code requirement sucks! But until we can run arbitrary
4621 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4623 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4624 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4625 about it and you will realize why. JRR 010720

5704 A printer and a printer driver are 2 different things.

5709 2 of them are the same make and model (laser A and B). But laser B
5710 has an 3000 sheet feeder and laser A doesn't such an option.
5711 Your third printer is an old dot-matrix model for the accounting :-).
5713 If the /usr/local/samba/lib directory (default dir), you will have
5714 5 files to describe all of this.
5716 3 files for the printers (1 by printer):
5717 NTprinter_laser A
5718 NTprinter_laser B
5719 NTprinter_accounting
5720 2 files for the drivers (1 for the laser and 1 for the dot matrix)

5722 NTdriver_printer model Y
