4510 this printer into the tdb. Later, new printers that use this driver will
4511 have this initialization information bound to them. This simulates the
4512 driver initialization, as if it had run on the Samba server (as it would
4513 have done on NT).
4515 The Win32 client side code requirement sucks! But until we can run arbitrary
4516 Win32 printer driver code on any Unix that Samba runs on, we are stuck with it.
4518 It would have been easier to use SetPrinter because all the UNMARSHALLING of
4519 the DEVMODE is done there, but 2K/XP clients do not set the DEVMODE... think
4520 about it and you will realize why. JRR 010720

5600 A printer and a printer driver are 2 different things.

5602 Why ? Simply because it's easier and it makes sense !
5604 Now explanation: You have 3 printers behind your samba server,
5605 2 of them are the same make and model (laser A and B). But laser B
5606 has an 3000 sheet feeder and laser A doesn't such an option.
5607 Your third printer is an old dot-matrix model for the accounting :-).
5609 If the /usr/local/samba/lib directory (default dir), you will have
5610 5 files to describe all of this.
5612 3 files for the printers (1 by printer):
5613 NTprinter_laser A
5614 NTprinter_laser B
5615 NTprinter_accounting
5616 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5617 NTdriver_printer model X
5618 NTdriver_printer model Y
