4618 b. Call DrvConvertDevMode with CDM_DRIVER_DEFAULT to get default DEVMODE
4619 2. Call SetPrinterData with the 'magic' key and the DEVMODE as data.
4621 The last step triggers saving the "driver initialization" information for
4622 this printer into the tdb. Later, new printers that use this driver will
4623 have this initialization information bound to them. This simulates the

5720 A printer and a printer driver are 2 different things.

5725 2 of them are the same make and model (laser A and B). But laser B
5726 has an 3000 sheet feeder and laser A doesn't such an option.
5727 Your third printer is an old dot-matrix model for the accounting :-).
5729 If the /usr/local/samba/lib directory (default dir), you will have

5732 3 files for the printers (1 by printer):
5733 NTprinter_laser A
5734 NTprinter_laser B
5735 NTprinter_accounting
5736 2 files for the drivers (1 for the laser and 1 for the dot matrix)

5738 NTdriver_printer model Y
