If you’re looking to improve the productivity and lower the operating costs of your business, the B420dn offers all of that and more.  The B420dn delivers up to 30 ppm, with the first page printing in as little as 5.5 seconds.  It produces output in black & white that’s clear and crisp, at up to 1200 x 1200 dpi resolution, using a two-piece consumables system for long-lasting performance and a low cost of operation.  All B400 Series printers come with duplex (2-sided) printing standard, leading to fewer user interventions and savings on media costs. The B420dn has a 530-sheet standard capacity which can also be expanded with a 530-sheet 2nd tray.  In terms of durability and reliability, B400 Series printers are tough—with a monthly duty cycle as high as 70,000 pages.  With USB and parallel interfaces, all B400 Series printers offer broad-based connectivity. Equipped with an OkiLAN® print server, the B410dn, B420dn and B430dn models make network printing more affordable—which translates into a much lower cost per user, a vital consideration as your office network grows and expands in functionality.
