Very fast, and good quality printed documents. I used an Ethernet cable to connect my computer to the printer; works excellent. I am NOT on a network, just 1 computer. I am not very computer literate, but managed this connection and printing quite easily.

The printer is a great machine in terms of time efficiency and time saving. How I got it is a little bit of headaches. Received the first one but it failed to install the software on my PC. Contacted HP Canada and was told the printer's warranty had expired 2 months earlier.

If you are keen on purchasing a high performance printer, then HP LaserJet Pro 400 Printer M401dn is an ideal option for you. It is capable of meeting all your office purposes. This printer develops extremely nice output, including high quality and clear pictures.

I have had an HP B/W printer for a decade and I finally decided to upgrade. It took over an hour on the phone with Tech Support to get this thing to finally install correctly. It randomly prints triangles over my reports. And it still won't print from tray 3.

Excellent laser printer for the money. Simple set up.

Nice little printer, but users were complaining it would go to sleep and they would manually have to turn the printer on to print. Turns out when the printer is connected via USB (which it was) it will go to sleep and power down the USB port, making the printer unreachable.

Small footprint; fast time-to-first-page; duplexes; excellent print quality

Cannot disable sleep when using USB interface; Fussy driver install

replaced a 20 year old HP laser that has given sterling service over the years - turned the M402 on and 'wow' - why did i wait so long to replace the old one - print quality is excellent but the speed the print arrives on the tray is just amazing compared to the old one - if i get 20 years out of...

Very nice monochrome printer. Text resolution is really good, and print speed is very fast. Double sided printing does not seem to slow the print speed down to any degree. The M402dw requires no cable connections when used with Wi-Fi.

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.
