2033 A printer and a printer driver are 2 different things.
2034 NT manages them separatelly, Samba does the same.
2035 Why ? Simply because it's easier and it makes sense !
2037 Now explanation: You have 3 printers behind your samba server,
2038 2 of them are the same make and model (laser A and B). But laser B
2039 has an 3000 sheet feeder and laser A doesn't such an option.
2040 Your third printer is an old dot-matrix model for the accounting :-).
2042 If the /usr/local/samba/lib directory (default dir), you will have
2043 5 files to describe all of this.
2045 3 files for the printers (1 by printer):
2048 NTprinter_accounting
2049 2 files for the drivers (1 for the laser and 1 for the dot matrix)
2050 NTdriver_printer model X
2051 NTdriver_printer model Y
2053 jfm: I should use this comment for the text file to explain
2054 same thing for the forms BTW.
2055 Je devrais mettre mes commentaires en francais, ca serait mieux :-)
