Trusted Reviews looked at the Epson EPL-N2550 A3 Mono Laser Printer

It's not often we test an A3 mono laser printer as few companies need
the larger size in a black and white print. That might be part of the reason you'll get little change out of =A31,000 for this Epson workgroup machine. Another reason could well be the fast claimed print speeds of 30ppm for A4 and 17ppm for A3 pages. Even so, at first glance, it looks expensive.
