4504 this printer into the tdb. Later, new printers that use this driver will
4505 have this initialization information bound to them. This simulates the
4506 driver initialization, as if it had run on the Samba server (as it would
4507 have done on NT).
4509 The Win32 client side code requirement sucks! But until we can run arbitrary
4510 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4512 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4513 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4514 about it and you will realize why. JRR 010720

5594 A printer and a printer driver are 2 different things.

5599 2 of them are the same make and model (laser A and B). But laser B
5600 has an 3000 sheet feeder and laser A doesn't such an option.
5601 Your third printer is an old dot-matrix model for the accounting :-).
5603 If the /usr/local/samba/lib directory (default dir), you will have
5604 5 files to describe all of this.
5606 3 files for the printers (1 by printer):
5607 NTprinter_laser A
5608 NTprinter_laser B
5609 NTprinter_accounting
5610 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5611 NTdriver_printer model X
5612 NTdriver_printer model Y
