4220 Set the DRIVER_INIT info in the tdb. Requires Win32 client code that:
4222 1. Use the driver's config DLL to this UNC printername and:
4223 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4224 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4225 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4227 The last step triggers saving the "driver initialization" information for
4228 this printer into the tdb. Later, new printers that use this driver will
4229 have this initialization information bound to them. This simulates the
4230 driver initialization, as if it had run on the Samba server (as it would
4231 have done on NT).
4233 The Win32 client side code requirement sucks! But until we can run arbitrary
4234 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4236 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4237 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4238 about it and you will realize why. JRR 010720

5290 2 of them are the same make and model (laser A and B). But laser B
5291 has an 3000 sheet feeder and laser A doesn't such an option.
5292 Your third printer is an old dot-matrix model for the accounting :-).

5297 3 files for the printers (1 by printer):
5298 NTprinter_laser A
5299 NTprinter_laser B
5300 NTprinter_accounting
5301 2 files for the drivers (1 for the laser and 1 for the dot matrix)

5303 NTdriver_printer model Y
