4661 A printer and a printer driver are 2 different things.
4662 NT manages them separatelly, Samba does the same.
4663 Why ? Simply because it's easier and it makes sense !
4665 Now explanation: You have 3 printers behind your samba server,
4666 2 of them are the same make and model (laser A and B). But laser B
4667 has an 3000 sheet feeder and laser A doesn't such an option.
4668 Your third printer is an old dot-matrix model for the accounting :-).
4670 If the /usr/local/samba/lib directory (default dir), you will have
4671 5 files to describe all of this.
4673 3 files for the printers (1 by printer):
4674 NTprinter_laser A
4675 NTprinter_laser B
4676 NTprinter_accounting
4677 2 files for the drivers (1 for the laser and 1 for the dot matrix)
4678 NTdriver_printer model X
4679 NTdriver_printer model Y
4681 jfm: I should use this comment for the text file to explain
4682 same thing for the forms BTW.
4683 Je devrais mettre mes commentaires en francais, ca serait mieux :-)
