The print speed on this printer rated at 21ppm is exactly the same as my previous printer. Wouldn't one think that 3-1/2 years later this speed could have been improved? The M451dw is certainly not "slow," it's just that I would have hoped for a minor improvement in print speed.

This is not a cheaply made machine. It's around 60 pounds out of the box and even though the photos make it look dinky, it's the size of standard black and white printer you probably have seen in an office environment. In comparison, I have an older Samsung black and white ML1740 laser printer. The Samsung fits neatly on a two drawer filing cabinet. The HP LaserJet 400 Pro is easily 1-1/2 to 2 times the size. So, be prepared to have a bit more space if you are used to the size of the sub $100 b&w laser printers out there.

Other quality features:

the paper drawer is sturdy, has adjustable bars within it to hold many different sizes of paper and fits completely within the machine. The front of the printer has a manual feed access that is smartly angled when fully opened so a) it doesn't take up a ton of space when fully open and, b) the manual feed uses gravity to its advantage so your paper goes through the printer without you having to babysit it. The manual feed has an extender you can pull out to hold legal sized stock in place. There is a handy RAM memory panel on the side which allows you to easily switch out the memory. By the way, so buy it at the same time you buy the printer so you aren't waiting forever for large layouts to print. The back has a door that gives you access to the printer rollers in case you have a jam. The toner is placed in the front of the machine. All four toner cartridges snap into position on the toner tray that easily pulls out. Everything has obvious handles and clicks into place when you close it, although you may notice a few 'fit' issues especially on the manual feed tray. So far, no big issues.


As with most printers, this one has a display that is menu based. It uses the forward/backward/OK strategy you may be familiar with if you've had to fix an issue with a laser printer at work. Fortunately, you can pretty much completely ignore this once you are networked to the printer as it comes with a web-enabled menu. Also, the HP print utility will allow the printer to tell you what problems its having and how to fix them. It's well thought out, very helpful and handy.

Wireless printing:

It's not completely obvious unless you've done this before. My recommendation: connect the printer by USB or ethernet to your computer and set it up that way, following all the instructions on the CD. If you are on Windows, use the smart installer. If you are on a Mac, I recommend using the add a printer under System Preferences. If you are tech savvy, the easiest way to get to the printer is to access its web-enabled printer menu by typing in its IP address in a browser window. That will give you full access to all the printers features in one easy and well-designed menu. Once everything is set up, all your iDevices will automatically print wirelessly as will your desktop or laptop no need to keep it plugged in to your computer by ethernet or USB. I haven't tried my Android device yet to see if those are just as easy, but I will follow up on that later.


This is the area that made me give the printer 4 stars. Out of the box, the color is decent, but not great. It's darker and more flat than an actual printed piece. If you aren't a designer who works with clients, I'm sure you will be very pleased with the color results, so keep in mind I'm being very picky because of what I do. The nice thing is that HP gives you complete control over contrasts, mid-tones, highlights and shadows so you can find the settings that work best for you. I'm assuming they found a happy medium between color quality and toner usage for their factory settings. I plan to update this review with settings I've found that get me as close to color accurate as possible. If anyone has played around with these, I'd love to hear about your results.


Once the printer is warmed up which is pretty fast, it prints at a decent rate. The speed isn't going to blow you away and if you use the double-sided print feature, expect that to add more time to your print run. All-in-all no big complaints visit here.

Double-sided printing:

Speaking of double-sided print outs, this is another great feature that works flawlessly, As the first side prints and comes out the top, the printer pulls it back in to print the second side. When you pull the document off the output tray, it reads exactly like a book and no need to manually turn pages around to read them properly.
