Design & Build
The M401d features duplex printing, but no network connectivity or Wi-Fi. Its 128 MB of memory allow for convenient sharing within a workgroup of twenty. It supports PCL5c, PCL 6 and Postscript 3.
This is a fast printer. At 33 pages per minute (ppm), it beats every other monochrome laser printer we've reviewed. Compare this to the Dell B1160w's 20 ppm, the Brother HL-2240's 25 ppm and the AcuLaser M2300DN's 32 ppm.
The print quality on the HP LaserJet Pro 400 M401d is good for plain text. However, for anything more demanding it quickly reaches its limits.
Power Use & Noise
While the M401d consumes an average amount of power (600 watts) while printing, on standby it consumes 6 watts where most printers (laser and inkjet combined) consume less than 1 watt. When it comes to noise levels, our sensor picked up 51 dB. Printers are considered "quiet" under 50 dB—so let's say this one's almost there.
Cost Per Page
The LaserJet Pro 400 M401 Series has the lowest cost per page of any monochrome laser printer we've reviewed over the past six months. By comparison, the Epson Aculaser M2300DN gets 3.3 pence per page and the Dell B1160w gets 3.4 pence per page. Then again, on colour laser printers the cost per page for black toner goes lower than that: 1.9 p for black toner on the HP LaserJet Pro 400 Color M451nw and 1.8 p on the OKI C331dn.

The LaserJet Pro 400 M401d is fast and easy to use. It can't print from mobile devices, doesn't feature any business apps and consumes more power on standby than average, but it prints quickly and has a reasonable cost per page.
