Excerpt: The HP LaserJet Pro 400 Color M451 series includes three workgroup printers . The M451nw comes with both wireless (802.11b/g/n) and wired Fast Ethernet 10/100 capabilities. The model we physically reviewed wasn’t the M451nw, but the more expensive (around £380) M451dw, which is in essence identical to the M451nw except that it comes with auto-duplexing – the M451nw is manual only.
