4156 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4157 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4158 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4160 The last step triggers saving the "driver initialization" information for
4161 this printer into the tdb. Later, new printers that use this driver will
4162 have this initialization information bound to them. This simulates the
4163 driver initialization, as if it had run on the Samba server (as it would
4164 have done on NT).
4166 The Win32 client side code requirement sucks! But until we can run arbitrary
4167 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4169 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4170 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4171 about it and you will realize why. JRR 010720

5193 2 of them are the same make and model (laser A and B). But laser B
5194 has an 3000 sheet feeder and laser A doesn't such an option.
5195 Your third printer is an old dot-matrix model for the accounting :-).
5197 If the /usr/local/samba/lib directory (default dir), you will have
5198 5 files to describe all of this.
5200 3 files for the printers (1 by printer):
5201 NTprinter_laser A
5202 NTprinter_laser B
5203 NTprinter_accounting
5204 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5205 NTdriver_printer model X
5206 NTdriver_printer model Y
