4519 have this initialization information bound to them. This simulates the
4520 driver initialization, as if it had run on the Samba server (as it would
4521 have done on NT).
4523 The Win32 client side code requirement sucks! But until we can run arbitrary
4524 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4526 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4527 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4528 about it and you will realize why. JRR 010720

5608 A printer and a printer driver are 2 different things.

5613 2 of them are the same make and model (laser A and B). But laser B
5614 has an 3000 sheet feeder and laser A doesn't such an option.
5615 Your third printer is an old dot-matrix model for the accounting :-).
5617 If the /usr/local/samba/lib directory (default dir), you will have
5618 5 files to describe all of this.
5620 3 files for the printers (1 by printer):
5621 NTprinter_laser A
5622 NTprinter_laser B
5623 NTprinter_accounting
5624 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5625 NTdriver_printer model X
5626 NTdriver_printer model Y
