4545 have this initialization information bound to them. This simulates the
4546 driver initialization, as if it had run on the Samba server (as it would
4547 have done on NT).
4549 The Win32 client side code requirement sucks! But until we can run arbitrary
4550 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4552 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4553 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4554 about it and you will realize why. JRR 010720

5628 A printer and a printer driver are 2 different things.

5630 Why ? Simply because it's easier and it makes sense !
5632 Now explanation: You have 3 printers behind your samba server,
5633 2 of them are the same make and model (laser A and B). But laser B
5634 has an 3000 sheet feeder and laser A doesn't such an option.
5635 Your third printer is an old dot-matrix model for the accounting :-).
5637 If the /usr/local/samba/lib directory (default dir), you will have
5638 5 files to describe all of this.
5640 3 files for the printers (1 by printer):
5641 NTprinter_laser A
5642 NTprinter_laser B
5643 NTprinter_accounting
5644 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5645 NTdriver_printer model X
5646 NTdriver_printer model Y
