HP LaserJet Pro 400 M451nw review
12 March 2012
Summary: The HP LaserJet Pro 400 Color M451nw's lack of an automatic duplexer is an issue that you can overcome by opting for the M451dn (no Wi-Fi) or the M451dw (with Wi-Fi and, despite the absence of the letter n in the name, ethernet). Alas, neither of those models can solve the problem of high per-page costs. Consider a high-end business inkjet MFP instead, which could save you a bundle on supplies over time.
