4561 have this initialization information bound to them. This simulates the
4562 driver initialization, as if it had run on the Samba server (as it would
4563 have done on NT).
4565 The Win32 client side code requirement sucks! But until we can run arbitrary
4566 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4568 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4569 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4570 about it and you will realize why. JRR 010720

5650 A printer and a printer driver are 2 different things.

5654 Now explanation: You have 3 printers behind your samba server,
5655 2 of them are the same make and model (laser A and B). But laser B
5656 has an 3000 sheet feeder and laser A doesn't such an option.
5657 Your third printer is an old dot-matrix model for the accounting :-).
5659 If the /usr/local/samba/lib directory (default dir), you will have
5660 5 files to describe all of this.
5662 3 files for the printers (1 by printer):
5663 NTprinter_laser A
5664 NTprinter_laser B
5665 NTprinter_accounting
5666 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5667 NTdriver_printer model X
5668 NTdriver_printer model Y
