The HP LaserJet Pro 400 M401dn monochrome laser printer is slow, but it?s a decent fit for micro and small offices that care more output quality than speed.

High-quality text; Ethernet; Built-in duplexer and 300-sheet capacity standard; 800-sheet maximum

Slow

The $399 HP LaserJet Pro 400 M401dw bundles all of HP's latest technologies into a tight package; you get Smart Install that eliminates the hassle of installing off a driver disc, ePrint remote access, and walk-up printing through the USB port on the front, but the 3.5-inch touch-screen display...

The HP LaserJet Pro 400 M401dw's direct USB port; wireless connectivity; and remote printing features offer a variety of ways to interact with the printer

HP Smart Install only works with Windows; and the flimsy touch-screen display impedes usability

While it won't win any speed records, this auto-duplexing laser offers superior print quality at a reasonable price. (The per-page cost is decent, but less so if you print a lot of pages.)

Excellent print quality; Color touch screen; Auto-duplexing ADF; Large paper-input capacity; EPrint and AirPrint support

Relatively slow for its class; No Wi-Fi connectivity

The HP LaserJet Pro 400 is a well-featured printer that has strong specifications for use in the office. The M401dw model has excellent connectivity alongside an accessible (if unreponsive) touchscreen.

Being a purchaser of HP products for the majority of my life, i must say that this printer is a big improvement on my old model, a Laserjet 4000. I was after a model spec for my small office which provided me with speed (i get around 27-30 pages per minute), yet was efficient and had a really good...

Fast; Efficient; very good new wireless features..

Maybe the size; but not too bad

Aimed primarily at a small office or workgroup, the HP LaserJet Pro M402dw ($349.99) is a strong candidate as a workhorse monochrome laser printer. Its claimed cost per page is a touch high and its text quality a touch low compared with its closest competition, but it still delivers a balance of speed, paper handling, output quality, and running cost that's suitable for medium duty in a small office. It's also small enough to place on a desk, making it an attractive choice as a heavy duty personal printer. Among the M402dw's ($349.00 at Amazon UK) direct competitors are the Dell B2360dn ($349.00 at Amazon UK) and the Brother HL-6180DW ($349.00 at Amazon UK) .

The key differences between them are that the Brother model offers a somewhat higher paper capacity and lower cost per page, while the Dell printer delivered significantly faster sp...
