5392 2 of them are the same make and model (laser A and B). But laser B
5393 has an 3000 sheet feeder and laser A doesn't such an option.
5394 Your third printer is an old dot-matrix model for the accounting :-).
5396 If the /usr/local/samba/lib directory (default dir), you will have

5399 3 files for the printers (1 by printer):
5400 NTprinter_laser A
5401 NTprinter_laser B
5402 NTprinter_accounting
5403 2 files for the drivers (1 for the laser and 1 for the dot matrix)

5405 NTdriver_printer model Y
