The Okidata Oki B4250 is a compact, grayscale small-office printer that best fits a text-happy small office or home. This machine creates prints on a par with laser quality, using LED arrays instead of a laser beam to paint a page--a technology that shaves a few dollars off the cost and aims to offer improved reliability. The B4250 includes a vendor-rated 23-pages-per-minute (ppm) engine that proved swift in our tests. Although at $241 it costs $90 more than the comparable Samsung ML-1740, the B4250 prints more quickly and is cheaper to maintain. Other Oki models, such as the B4350n, work with Macs and offer a full-featured control panel and an Ethernet interface. But when speed and low upkeep price matter more than perfect print quality, we favor the B4250. The squat Okidata Oki B4250, available in a black or putty color, is nondescript but compact and sturdy. It measures 14 inches wide by 15 inches deep and weighs 20 pounds--easy to tote around if you like to rearrange your office furniture. Okidata's hieroglyphic labeling makes the control panel hard to decipher, but with only four blinking lights and a single button, you won't need the Rosetta stone to translate. Both a parallel port for older PCs and an up-to-date USB 2.0 port stick out the back end. A single screw fastens a plate over the controller and its empty memory slots, making it easy to install memory upgrades.
The control panel perches on the brow above the output tray, with a button to pop open the lid like the hood of a car, exposing the paper path, the toner, and the imager. We found the B4250 easy to use, despite the challenge of adding paper. The main paper tray's handle is knuckle-scrapingly shallow; to keep skin attached to bone, we opened the tray by bracing a thumb against the thin auxiliary flap.
The Good
The Bad
The Bottom Line
The Oki B4250 lacks a networking option, so if you aim to share your printer, turn instead to the similar B4350, which costs $74 more and accepts an add-on Ethernet card. Alternately, choose the B4250's sibling, the B4350n, which is $178 more with a network-interface card installed. (CNET did not test the network models' performance.)
The Okidata B4250 performed decently in CNET Labs' tests. Though far behind the fastest laser, at 18.8 pages per minute (ppm) for text and 17.8ppm for graphics, it still beat the popular HP LaserJet 1012.The B4250's print quality was sharp overall. It was clear even at the smallest font sizes, although the text looked patchy and light. Graphics, however, suffered more from the high contrast. With even a cursory glance, we could see that images were washed out or uneven.
From the performance perspective, the Oki B4250 is a decent grayscale printer that quietly and smoothly gets the job done. We tested it at the manufacturer's default settings, which can be adjusted to improve performance.

Okidata offers free telephone tech support 24/7 on a toll-free line and answers tech-support calls for the life of the Okidata Oki B4250, rather than the duration of its one-year exchange warranty. The warranty also covers the LED printhead for a generous five years. The overnight-exchange repair plan asks you to pay outbound shipping; Okidata pays for the return. You can double the length of the printer's warranty for $79 or triple it for $219--a nice option.The concise Oki B4250 setup and software-installation guide booklets suffer from grainy photos, but they carefully step you through the easy process. The printer's onscreen PDF manual, however, sometimes puzzled us by mixing together information on the B4250 and similar models. Under Windows XP, the installation flowed smoothly, despite the software's unnecessary questions about the printer model. Okidata's Web site lists only two articles for the B4250, so you're better off e-mailing questions directly to tech support.
