4543 1. Use the driver's config DLL to this UNC printername and:
4544 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4545 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4546 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4548 The last step triggers saving the "driver initialization" information for
4549 this printer into the tdb. Later, new printers that use this driver will
4550 have this initialization information bound to them. This simulates the
4551 driver initialization, as if it had run on the Samba server (as it would
4552 have done on NT).
4554 The Win32 client side code requirement sucks! But until we can run arbitrary
4555 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4557 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4558 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4559 about it and you will realize why. JRR 010720

5651 A printer and a printer driver are 2 different things.

5655 Now explanation: You have 3 printers behind your samba server,
5656 2 of them are the same make and model (laser A and B). But laser B
5657 has an 3000 sheet feeder and laser A doesn't such an option.
5658 Your third printer is an old dot-matrix model for the accounting :-).
5660 If the /usr/local/samba/lib directory (default dir), you will have
5661 5 files to describe all of this.
5663 3 files for the printers (1 by printer):
5664 NTprinter_laser A
5665 NTprinter_laser B
5666 NTprinter_accounting
5667 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5668 NTdriver_printer model X
5669 NTdriver_printer model Y
