4201 Set the DRIVER_INIT info in the tdb. Requires Win32 client code that:
4203 1. Use the driver's config DLL to this UNC printername and:
4204 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4205 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4206 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4208 The last step triggers saving the "driver initialization" information for
4209 this printer into the tdb. Later, new printers that use this driver will
4210 have this initialization information bound to them. This simulates the
4211 driver initialization, as if it had run on the Samba server (as it would
4212 have done on NT).
4214 The Win32 client side code requirement sucks! But until we can run arbitrary
4215 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4217 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4218 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4219 about it and you will realize why. JRR 010720

5270 2 of them are the same make and model (laser A and B). But laser B
5271 has an 3000 sheet feeder and laser A doesn't such an option.
5272 Your third printer is an old dot-matrix model for the accounting :-).
5274 If the /usr/local/samba/lib directory (default dir), you will have

5277 3 files for the printers (1 by printer):
5278 NTprinter_laser A
5279 NTprinter_laser B
5280 NTprinter_accounting
5281 2 files for the drivers (1 for the laser and 1 for the dot matrix)

5283 NTdriver_printer model Y
