It connects to my WiFi which made siting it more flexible and freed up a USB socket on the computer. It's fast and efficient at printing; good copy quality for a laser printer. It's also fairly compact (though not as small as my old HP Laser Jet).

Some devices can't seem to get the printer out of power save . This forces me to manually go poke the printer. This is very annoying when not in the same room.

Quality printer

Power save should be optional

While the setup for the printer wasn't quite as easy as plug-in and go, it was a relatively quick and painless procedure. The prints process quickly and come out nice and clear in their details. The input tray holds a surprising amount of paper so you won't have to fill it up very often.

I've been buying the 400 series laserjets for several years. I think we have 400n, 401n, 402n, and now 404n printers in our office. We mostly use them for offices that require more than normal printing output. We also have one that is used for a small workgroup of 4 cubicles. I can't complain.

We have used this printer for a few weeks now, all good and no complains so far.

Spec sheet says that it will print envelopes but it will not.

HP LaserJet printers are generally solid printers and this unit is as well, with a couple caveats: Make sure you use HP toner if you want good quality prints; Make sure you get the thing configured properly if you have an enterprise environment and need it to be user-autonomous.

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

I like it. Simple to set up. The queue is saved even if I shut down the computer. The sharp images and text are rapidly created. Best of all, it does not have any dangerous radio frequency emitting WiFi; thus I did not have to spend time searching and disabling the WiFi circuit board.
