Brother makes great printers
I absolutely LOVE this brother printer. My son, who is a computer geek, encouraged me to get a Brother L2350 which uses a cartridge for ink. I got so fed up with the expensive ink for other manufacturers printers. We print about 10 to 15 pages per day and the cartridge in the 2350 lasted over one year. That prompted me to look at a color printer for personal/business use and the 3720 is spot on. Don't expect to get great color piectures fromt this printer, it was not designed for this; graphics for documents and great. There are four cartridges which should last a year or so and the printer is much more reliable and funtional. Money well spent.

Quality Hardware, Forgo the App
I bought this for home use. Love this printer. It does everything you would expect and more. The print and color quality are exceptional. One observation: don't bother downloading the Brother Mobile App. I find that it rarely works and often enters into the spinning "loading" icon of death, requiring a termination of the process. But the printer is great without the app.

Love it.
Easy install, silent when printing, nice functionality, scanning and copying documents.

It stops working after a few months and customer service is awful.
***Update after several months with a new reason this printer is the worst thing ever.... it counts pages, not toner. When the printer "thinks" the toner is empty, it just stops printing. There is no way to reset the page counts (unlike in previous Brother printers). There is no way to bypass this. You can't just print in black and white when a color cartidge is out. It just stops. There is no printing until you install a new cartridge. So, make sure you have plenty on hand because this sucker will stop and there's nothing you can do about it. If you are mid-big presentation or report? Too bad. Stop and go to the store because this printer won't budge. These toner cartridges have "chips" on them now in order to prevent you from reseting the page count. And get this: it counts pages if you aren't printing in black and white! You can lift it out and feel how heavy it is and know there is plenty of toner in there but - nope! You printed too many pages so now your printer won't let you do anything. All to make you have to spend a gazillion dollars on new toner cartridges even though you probably have months left of toner. Ridiculous. This is the worst product I have ever purchased. Avoid, avoid, avoid. I should have listened to the reviews. This printer stopped working after 7 months. Never was able to get the bluetooth stuff to work. Two days ago I got an error message saying I had installed a "non-genuine toner cartridge" when I had not changed anything or touched any toner since receiving it. It was still the original toner it came with. It wouldn't let me move past the error message to continue printing (unless I wanted to "void my warranty," which I was not going to do since it was already having issues). Off to customer service I go! The first attempt with customer service resulted in a disconnection (the agent just stopped responding... good times). He said I could just click "no" and keep right on printing, but the video shows that was not the case. After that he just disappeared and didn't respond anymore so I had to start a new chat with another agent. The next agent at least tried, but took an hour, had me disassembling the dang thing, and didn't solve any problems. They are sending me a new cyan cartridge, but I'm not feeling confident. I still can't print and am still seeing an error message. Just really, really bad. Don't buy it.

Dependable
Excellent printer. We had a smaller cheaper printer and it would lose WiFi connectivity all of the time. We got tired of it and invested some extra money into the Brother . It is dependable and it’s more professional than my old Epson. Excellent so far.

Loving this printer for my Linux system
Bought in March 2024. Writing review in December 2024. I regularly need color copy for my job that won't run if it gets wet out at a job site. After reading a lot about printers on Linux forums, I decided to go with the Brother brand. This thing is a workhorse. I've only had 1 jam since I bought it and it was in the summer months when the paper may have been a bit humid. Other than that, no issues. It prints way faster than deskjet type printers and like I said doesn't run if the page gets wet like deskjet printouts do. I use it with my self-built Linux system. Primary use is color printing. Also do color copying. Haven't used the other features yet. Wifi works fine. Prints from phone or tablet (apple and android) as easily as from desktop PC. Pretty easy to set up on Linux for my needs. We are work-from-home here and my boss likes it so much that he also bought one for his house after being a deskjet user for years. Added bonus, we enjoy doing puzzles. Some puzzles do not come with the poster, so I take a photo and print it on the color printer. Comes out nice and crisp. Not as bright or well defined as the glossy artwork on the puzzle boxes since I'm using plain copier paper. I haven't tried getting any kind of glossy paper to see if that makes a difference. I may have to source some glossy paper and try that out next. Works well with generic cartridges which is a plus. Read reviews on those before buying though, just in case any particular brand has issues. Get the XL version, more pages per cartridge.

Very nice so far
Only had it a week but so far, so good. This is my first home laser printer. This the weighs a ton. I almost needed a fork lift to get it from my front porch into the house 😂. Fortunately, the printer is in a big bag with handles that allows you to easily lift it out of the box. Set up was fairly easy. Although I could not get the printer to connect to my home Wi-Fi network through the Epson app that I downloaded for the sprinter so I ended up just going through the printers Wi-Fi set up and connecting it to my route, which went very smoothly other than that, the printer set up was pretty straightforward. The iPhone app that I am using and downloaded works really well through the printer. I’m glad I don’t have to do all that my former old Epson inkjet and do it all through my computer ,so that was nice. It’s no speed demon, but it certainly has a very good quality. Print I’ve done a little black-and-white a little color only a weekend so time will tell but so far I’m very happy with this printer.

incredibly easy to set up. No issues connecting to wifi also prints from the phone with no issues worked right out of the box.

Great printer. Tired of getting scammed with inkjet printers. Works well. Enjoy printer when not at home. Upfront costly but in the long run will be cheaper than buying inkjet ink

It worked for only 2 days and then stopped working. We requested a replacement, and Amazon replied that we should return the item instead. Amazon mentioned they would provide a pickup time, but we never received any pickup schedule, and the item was not picked up. Now, after waiting several days for their response, we are no longer able to submit a return request again through the system.

I purchased this printer to replace two old tired monochrome laser printers built by "another company". I have sporadic printing needs, including colour, and have found that ink jets tend to have problems when they aren't used regularly. My work computers run Ubuntu Linux and getting the printer up and running with them was simple, including both printing and scanning. The Brother drivers that are automatically loaded in Ubuntu 24.04 (latest version) work without a hitch. No problems with the wifi connection either. I really appreciate the printer managing its firmware updates on its own, so that I don't have to hunt them down - the control panel just indicates when an update is ready to install. The print quality seems great. I haven't tried printing on glossy paper, but certainly the plain paper quality is more than fine. The sheet feeder on the document scanner works without a hitch. In sum, I'm super happy to have made the decision to acquire this printer. Highly recommended, and I would buy another.

Great unit and I'm definitely a convert from HP to Brother now. Difference between next model up and thus one is this unit does not support duplex scanning (2 sided scanning) and does 19 pages per min compared to the 31 pages the next model up does for $299 more. Good buy for $499.
