I'm really pleased - and pleasantly surprised
The setup on this printer for WiFi printing was easy and straightforward. Not a single problem, yay. I was mega-concerned about the setup process based on reviews I've read about all of the other printers. Print quality is great, and the Windows 10 driver works perfect - unlike my older HP's driver. So far I'm very pleased. Now I see that my doctor's office has a handful of this same printer scattered around too. The biggest selling point for me was that I have *not* yet seen comments saying that 3rd part toner cartridges will not work. Compare this to my personal experience with HP and Canon - older printers that I have.

Fast Small Lexmark Printer Get the Job Done!
Easy to set up and use! I appreciate the smaller size than my old Dell laser printer. The Lexmark will get a workout when tax season arrives, and it’s ppm output is one reason I purchased the printer !

So far, not good.
Very disappointed with this printer. Constant jams, and now the digital read-out tells me my printer cartridge is the wrong brand? (It’s the original that came with the printer.) Hoping I can return.

First impressions - so far so good
This was a replacement for an 8 year old color laser that failed. It is smaller, lighter and faster. I found thai I rarely needed color so toner should be cheaper. The printer was effectively packaged so arrived in perfect condition. The included documenttion is basialy non existent. A pictorial set up page with zero captions is much less clear than the writers think it is. Fortunately there is a full manual online as well as a set up video. Setup and software confuguration was straight forward and worked without error. One nit although not shown in the instructions, the printer needed some basic info (date, time, language) entered via the control panel before it worked. Once done the printer worked as advertisedd producing clear, sharp printing with double sided printing. One final note. The Lexmark online registration page inissts on the user giving permission to recieve their spam. This is unacceptable.

Razor sharp!
Very impressive output can’t be beaten. Type it, scan it, print it; you’ll be satisfied that this printer is a top performer.

Works great tight out of the box
I have tried several other brands, they have had a bad habit of losing connectivity and updates that only screw up all the settings and make connectivity less reliable. They never failed to deliver new ways to charge for things though. If you want a printer that will simply print when you tell it to, this one is highly recommended.

Lexmark MS431dw B&W Printer Does It All
This printer replaced a barely used Xerox B&W laser printer because I could never get the Xerox to do what I needed which was to work on both WiFi and Ethernet at the same time. It also does USB although I did not need it. I finally gave up and bought this Lexmark. It does exactly what I needed right from the start. The only "negative" might be the small LCD screen but honestly, once you set up the printer either via the iPhone or Android app or a desktop computer, you won't need the screen. The small size keeps the printer costs down and much more important is to buy a brand with good reviews which Lexmark does have. ---------------------------------------------------------------------------------------------------------------------------------------- This is a small profile unit and since it is a laser printer, the per page cost is VERY, VERY small. Ink Jet printers are cheaper to buy but the media cost is very high compared to a laser printer and I don't need color. I had installed other Lexmark printers first which is why I bougth this for myself. I will rarely do any printing but I wanted it to work without problem when needed and this seems to fit the bill. It fully supports current Mac & Win OS versions and make sure whatever you buy has a good record of doing this. Not all brands do so don't assume this can not be an issue.
