4149 Set the DRIVER_INIT info in the tdb. Requires Win32 client code that:
4151 1. Use the driver's config DLL to this UNC printername and:
4152 a. Call DrvPrintEvent with PRINTER_EVENT_INITIALIZE
4153 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4154 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4156 The last step triggers saving the "driver initialization" information for
4157 this printer into the tdb. Later, new printers that use this driver will
4158 have this initialization information bound to them. This simulates the
4159 driver initialization, as if it had run on the Samba server (as it would
4160 have done on NT).
4162 The Win32 client side code requirement sucks! But until we can run arbitrary
4163 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4165 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4166 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4167 about it and you will realize why. JRR 010720

5194 2 of them are the same make and model (laser A and B). But laser B
5195 has an 3000 sheet feeder and laser A doesn't such an option.
5196 Your third printer is an old dot-matrix model for the accounting :-).
5198 If the /usr/local/samba/lib directory (default dir), you will have
5199 5 files to describe all of this.
5201 3 files for the printers (1 by printer):
5202 NTprinter_laser A
5203 NTprinter_laser B
5204 NTprinter_accounting
5205 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5206 NTdriver_printer model X
5207 NTdriver_printer model Y
