5189 A printer and a printer driver are 2 different things.
5190 NT manages them separatelly, Samba does the same.
5191 Why ? Simply because it's easier and it makes sense !
5193 Now explanation: You have 3 printers behind your samba server,
5194 2 of them are the same make and model (laser A and B). But laser B
5195 has an 3000 sheet feeder and laser A doesn't such an option.
5196 Your third printer is an old dot-matrix model for the accounting :-).
5198 If the /usr/local/samba/lib directory (default dir), you will have
5199 5 files to describe all of this.
5201 3 files for the printers (1 by printer):
5204 NTprinter_accounting
5205 2 files for the drivers (1 for the laser and 1 for the dot matrix)
5206 NTdriver_printer model X
5207 NTdriver_printer model Y
5209 jfm: I should use this comment for the text file to explain
5210 same thing for the forms BTW.
5211 Je devrais mettre mes commentaires en francais, ca serait mieux :-)
