HP LaserJet M451dn Review: First Look

by Reads (11,170)

HP introduced a new line of LaserJet Pro devices earlier this year at MacWorld, following on the heels of CES 2012. The LaserJet Pro Series, consisting of six new configurations, are targeted at small and medium sized businesses (SMB) looking to add color to print flow or update their current color laser-class device.

We recently got two of the new configurations but today we’ll be focusing on the LaserJet Pro 400 M451dn, the single function model offering print speeds up to 21 ppm, a print resolution up to 600 x 600 dpi, 250-sheet paper tray, automatic duplexing and network connectivity.

Build and Design
The LaserJet Pro 400 M451dn (from here on referenced as the M451dn for the purpose of brevity) resembles other single function laser printers we’ve seen from HP in the past. A mixture of gray and black paneling, the box itself is fairly compact but surprisingly heavy when I lifted it into the light tent (52 lbs according to HP). The approximate dimensions are 16 x 19 x 13-inches, but with the output tray and/or multipurpose tray extended, the dimensions stretch to 16 x 27 x 13-inches.

The design is fairly simple since it’s a single function printer with a two-line display and modest control panel found to the left of the 150-sheet output bin. It consists of a two directional navigation with ok, back and cancel buttons. There are also six LED lights that alert customers to ink, power and print status.

The 50-sheet multipurpose tray folds out from the front of the M451dn and is designed for different types of media beyond the standard letter sized copy paper; think envelopes, postcards, labels, transparencies, etc.

Not that you can’t use the 250-sheet paper tray for all the media listed above, it is adjustable to fit an array of different sized media. Customers with a heavier print flow can also purchase an additional 250-sheet paper drawer.

You can access the four toner cartridges by pulling open the front of the M451dn and then sliding out the toner tray. The M451dn ships with a full set of toner cartridges (CMYK), but replacement HP305A cartridges are available through HP and authorized retailers.
