1638 A printer and a printer driver are 2 different things.
1639 NT manages them separatelly, Samba does the same.
1640 Why ? Simply because it's easier and it makes sense !
1642 Now explanation: You have 3 printers behind your samba server,
1643 2 of them are the same make and model (laser A and B). But laser B
1644 has an 3000 sheet feeder and laser A doesn't such an option.
1645 Your third printer is an old dot-matrix model for the accounting :-).
1647 If the /usr/local/samba/lib directory (default dir), you will have
1648 5 files to describe all of this.
1650 3 files for the printers (1 by printer):
1653 NTprinter_accounting
1654 2 files for the drivers (1 for the laser and 1 for the dot matrix)
1655 NTdriver_printer model X
1656 NTdriver_printer model Y
1658 jfm: I should use this comment for the text file to explain
1659 same thing for the forms BTW.
1660 Je devrais mettre mes commentaires en francais, ca serait mieux :-)
