4805 A printer and a printer driver are 2 different things.
4806 NT manages them separatelly, Samba does the same.
4807 Why ? Simply because it's easier and it makes sense !
4809 Now explanation: You have 3 printers behind your samba server,
4810 2 of them are the same make and model (laser A and B). But laser B
4811 has an 3000 sheet feeder and laser A doesn't such an option.
4812 Your third printer is an old dot-matrix model for the accounting :-).
4814 If the /usr/local/samba/lib directory (default dir), you will have
4815 5 files to describe all of this.
4817 3 files for the printers (1 by printer):
4818 NTprinter_laser A
4819 NTprinter_laser B
4820 NTprinter_accounting
4821 2 files for the drivers (1 for the laser and 1 for the dot matrix)
4822 NTdriver_printer model X
4823 NTdriver_printer model Y
4825 jfm: I should use this comment for the text file to explain
4826 same thing for the forms BTW.
4827 Je devrais mettre mes commentaires en francais, ca serait mieux :-)
