Lexmark B3442dw: Compact Mono Printing Without Compromise

The Lexmark B3442dw is a compact A4 mono laser printer built for small offices and home workspaces that still need serious speed. It prints at up to 42 pages per minute, with standard duplex on every job. Specifically, its light, steel-framed design and standard Wi-Fi suit desks, side tables, and tight spaces where a bulkier printer wouldn’t fit. Additionally, its 1GHz dual-core processor keeps everyday jobs moving quickly, without the footprint of a larger workgroup machine.

42ppm Mono Printing in a Compact Frame

The Lexmark B3442dw prints at up to 42 pages per minute, with the first page landing in as little as 5.9 seconds. So it clears everyday print runs quickly, without making you wait at your desk. Its 1GHz dual-core processor handles multi-page jobs smoothly, even with the standard 256MB of memory. Because two-sided printing comes as standard, every job saves paper automatically, with no extra setup required.

Print resolution reaches up to 2400 x 600 dpi, so text and fine detail come out sharp on every page. Furthermore, measuring just 222mm high, 368mm wide and 363mm deep, it fits almost anywhere a standard printer can’t. As a result, it suits desks, shelves, and shared spaces where size genuinely matters.

Wi-Fi, Ethernet and Built-In Security

You can connect the B3442dw via USB 2.0 for a straightforward desktop setup. Alternatively, standard Ethernet gives you reliable network integration, while built-in 802.11b/g/n Wi-Fi lets you print wirelessly without running a single cable. Because of this, it adapts easily to home offices, hot-desking areas, and small teams that need flexible connectivity without extra hardware.

Security comes built in as standard, not bolted on afterwards. The B3442dw includes Lexmark’s full-spectrum security architecture, protecting your documents on the device, over the network, and everywhere in between. Also, its Confidential Print feature holds sensitive jobs at the printer until you enter a simple PIN, so nothing sits exposed in the output tray. In fact, a range of embedded features work continuously to harden the device against attacks, so your print environment stays protected.

Paper Handling and Toner That Goes the Distance

The standard 250-sheet input tray pairs with a 100-sheet multipurpose feeder, so you can switch between plain paper and envelopes or labels without reloading the main tray. Media sizes range from A6 up to Legal, meaning it handles everything from compact forms to longer documents with ease. Meanwhile, the 150-sheet output bin keeps finished jobs tidy and ready to collect.

For growing print volumes, an optional 550-sheet tray expands total input capacity up to 900 sheets. So the printer scales alongside your workload, rather than holding it back. Extra High Yield Unison toner is also available, delivering up to 6,000 pages of output for less frequent changeovers. Additionally, a steel frame and lifetime imaging components mean long life and minimal maintenance, with a maximum monthly duty cycle of 80,000 pages, well beyond the 800 to 8,000-page range Lexmark recommends for steady day-to-day use.

Refurbished and Tested In-House

Our own technicians refurbish every unit we sell. We don’t outsource this step. First, we test print quality and resolution accuracy. Next, we check duplex operation, paper feed reliability, and connectivity across USB, Ethernet, and Wi-Fi. We also verify the display and control panel respond correctly. Then, we clean each unit thoroughly, inside and out, before it ships. For the full picture, you can read more about us.

Each printer ships with a 90-day return-to-base warranty, including a 14-day return window. This covers you from day one. You’ll find full terms on our terms & conditions page. We also offer free delivery to mainland UK addresses. So the price you see is the price you pay.
