It was a workhorse for our laboratory and we got this one to replace the same one which worked until an internal part gave out. It lasted and lasted which is why we got another one

bottom line is this...this printer is $289.00. a 4 pack of toner to refill it is $352.00. WHY would i not just buy a brand new printer instead of refilling it with toner for more money if i recall, its been this price for a long time...this is not a sale...

crisp; clear print jobs; duplex printing is a big plus for our assembly department (printing instructions to go in product packages)

none so far; but only been using it a month

I have spent hours on the phone with HP support trying to get the printer to work wirelessly. They were supposed to call me again last night to continue, but I got an email saying they were busy. I was going to buy 2, glad I didn't. It may have a great quality print, but I have no way of knowing.

The $450 HP LaserJet Pro 400 Color M451nw color laser printer has nice output and is relatively speedy considering the price.

We were replacing an HP M3035 that was 4 years old and not worth repairing. The M475 is much sleaker in design, but seems to give up some speed to our old machine, which was surprising and disappointing.

HP's LaserJet Pro 400 Color M451nw is a workgroup printer that produces strong and fast output.
