5376 2 of them are the same make and model (laser A and B). But laser B
5377 has an 3000 sheet feeder and laser A doesn't such an option.
5378 Your third printer is an old dot-matrix model for the accounting :-).

5385 NTprinter_laser B

5387 2 files for the drivers (1 for the laser and 1 for the dot matrix)
