4581 Set the DRIVER_INIT info in the tdb. Requires Win32 client code that:
4583 1. Use the driver's config DLL to this UNC printername and:
4584 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4585 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4586 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4588 The last step triggers saving the "driver initialization" information for
4589 this printer into the tdb. Later, new printers that use this driver will
4590 have this initialization information bound to them. This simulates the
4591 driver initialization, as if it had run on the Samba server (as it would
4592 have done on NT).
4594 The Win32 client side code requirement sucks! But until we can run arbitrary
4595 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4597 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4598 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4599 about it and you will realize why. JRR 010720

5679 A printer and a printer driver are 2 different things.

5684 2 of them are the same make and model (laser A and B). But laser B
5685 has an 3000 sheet feeder and laser A doesn't such an option.
5686 Your third printer is an old dot-matrix model for the accounting :-).
5688 If the /usr/local/samba/lib directory (default dir), you will have
5689 5 files to describe all of this.
5691 3 files for the printers (1 by printer):
5692 NTprinter_laser A
5693 NTprinter_laser B
5694 NTprinter_accounting
5695 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5696 NTdriver_printer model X
5697 NTdriver_printer model Y
