4562 have this initialization information bound to them. This simulates the
4563 driver initialization, as if it had run on the Samba server (as it would
4564 have done on NT).
4566 The Win32 client side code requirement sucks! But until we can run arbitrary
4567 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4569 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4570 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4571 about it and you will realize why. JRR 010720

5651 A printer and a printer driver are 2 different things.

5656 2 of them are the same make and model (laser A and B). But laser B
5657 has an 3000 sheet feeder and laser A doesn't such an option.
5658 Your third printer is an old dot-matrix model for the accounting :-).
5660 If the /usr/local/samba/lib directory (default dir), you will have

5663 3 files for the printers (1 by printer):
5664 NTprinter_laser A
5665 NTprinter_laser B
5666 NTprinter_accounting
5667 2 files for the drivers (1 for the laser and 1 for the dot matrix)

5669 NTdriver_printer model Y
