The Good Impressive output speed and print quality; networking with Ethernet port; duplexer for double-sided printing; extra-large 350-sheet paper input tray.
The Bad Lacks desktop companion software; no USB cable included.
The Bottom Line The Oki B431DN is truly a workhorse black-and-white laser printer, with rapid output speed and high print quality. Combined with extra features like an autoduplexer and a large paper input capacity, the Oki B431DN is worth your dollar.
The Oki B431DN's drab black exterior and boxy shape make it easily lost in a pile of other monochrome laser printers, but this one deserves your extra attention. Modern laser printers with extra features--like an autoduplexer for double-sided prints, an extra-large 350-sheet paper input tray, and an open Ethernet port that lets multiple users print at the same time--usually cost more than $400, but the Oki B431DN offers all of the above for an affordable $350, the same price as less functional models like the Samsung ML-2851ND. On top of its affordable price, the Oki B431DN also delivers prints quickly and with superior image quality. This printer meets and exceeds our expectations for a small business or home office imaging device and earns our enthusiastic recommendation.
Like most monochrome printers, don't expect to see the B431DN strutting down the catwalk--its matte black design is meant to match the universally drab aesthetic of most office electronics, but what it lacks in elegance, it makes up for in utility. The printer is easy to pick up at just under 26 pounds (average for a laser printer), and at 9.6 inches tall, 15.2 inches wide, and 14.3 inches deep, it's small enough for one person to transport.
You'll interact with the printer primarily through the top of the device: there you'll find the standard output tray with a small plastic tab that flips out to corral finished prints, as well as the control panel and two-line LCD screen. Since the B431DN is only capable of outputting black and white, the operation is very straightforward, and a two-line LCD is all you'll need to control it. Underneath the screen you'll see a directional pad for navigating through the onscreen menus, an online button, a cancel button, and two skinny LED lights that blink to indicate readiness or if there are any problems that require your attention.
