5629 A printer and a printer driver are 2 different things.
5630 NT manages them separatelly, Samba does the same.
5631 Why ? Simply because it's easier and it makes sense !
5633 Now explanation: You have 3 printers behind your samba server,
5634 2 of them are the same make and model (laser A and B). But laser B
5635 has an 3000 sheet feeder and laser A doesn't such an option.
5636 Your third printer is an old dot-matrix model for the accounting :-).
5638 If the /usr/local/samba/lib directory (default dir), you will have
5639 5 files to describe all of this.
5641 3 files for the printers (1 by printer):
5644 NTprinter_accounting
5645 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5646 NTdriver_printer model X
5647 NTdriver_printer model Y
5649 jfm: I should use this comment for the text file to explain
5650 same thing for the forms BTW.
5651 Je devrais mettre mes commentaires en francais, ca serait mieux :-)
