1365         A printer and a printer driver are 2 different things.
1366         NT manages them separatelly, Samba does the same.
1367         Why ? Simply because it's easier and it makes sense !
1368
1369         Now explanation: You have 3 printers behind your samba server,
1370         2 of them are the same make and model (laser A and B). But laser B
1371         has an 3000 sheet feeder and laser A doesn't such an option.
1372         Your third printer is an old dot-matrix model for the accounting :-).
1373
1374         If the /usr/local/samba/lib directory (default dir), you will have
1375         5 files to describe all of this.
1376
1377         3 files for the printers (1 by printer):
1378                 NTprinter_laser A
1379                 NTprinter_laser B
1380                 NTprinter_accounting
1381         2 files for the drivers (1 for the laser and 1 for the dot matrix)
1382                 NTdriver_printer model X
1383                 NTdriver_printer model Y
1384
1385 jfm: I should use this comment for the text file to explain
1386         same thing for the forms BTW.
1387         Je devrais mettre mes commentaires en francais, ca serait mieux :-)
