Works Great In My Home Office
Love it. Works great wirelessly for my home office. I’ve been extremely impressed with the Brother MFC-L3720CDW. Setup was quick and straightforward, and the wireless connection has been reliable from day one. Print quality is sharp, colors come out vibrant, and documents print fast without constant delays or paper jams. The scanner works great, especially for multi-page documents, and the touchscreen interface is simple to navigate. I also appreciate how quiet the printer is compared to others I’ve owned. It handles everyday printing for both home and business use very efficiently. Another big plus is the toner efficiency. The cartridges seem to last much longer than inkjet printers, which saves money over time. Overall, this printer feels well-built, dependable, and professional. Highly recommend for anyone looking for a solid all-in-one color laser printer.

Great Printer for Home and Office Use
I really like this Brother printer. It prints fast, the colors look great, and the print quality is excellent. It was also easy to connect to WiFi and use from my phone. Perfect for school work, office tasks, and everyday use. Great purchase.

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.

Works great
I have been using the monochrome Brother laser printer and love it. The cost for the color printer is good, so I purchased this color machine. It was easy to set up. It came with all the toner and cartridge installed easily. It's quieter than my monochrome machine. It printed everything quickly and the quality is really good. I bought laser photo paper and printed some photos. The inkjet printers I feel make a better quality photo, but the prints on this machine are still good and people were happy with them. The only issue is the paper feed when printing 30 bulletins for our church. The paper feed is different than the monochrome and sometimes two pages go through at the same time with half the bulletin on the bottom of one page and half on the top page. Also, because there are 4 hot rollers the paper tends to curl up so I have to keep an eye on the output or the copies fall on the floor. The machine is well worth the cost and I am glad to have purchased it.

Fantastic Printer
This is a great printer, I have had it for 2.5 years now and have not ran into any issues. Toner also lasts a long time as I have just ran out of the toner originally provided with the printer.

Easy setup
UPDATE: 02/06/26 Had to remove 1 star for that constant incorrect password whenever I try to update using the application on my desktop. It also errors out (Unable to reach server) when I try to log into my account from the same application. However, it does update when I do it from the printer itself, without having to enter my password. The printer does not seem to talk to my PC because even when the update is comleted on the printer itself, the PC application is still notifying me about a pending update. I have always used Epson and that old printer that used ink jet cartridges is the worst. I waste ink cleaning the printer head every single time before I print the actual documents I need, otherwise it would print with gaps or misaligned texts. This is my first Brother device. PROs: Setup was easy. Works on both proprietary and open source OS. My PC uses Linux Mint and I added it from network, and Linux has a native scanner application that picked it up without a problem. I also added it to my Windows-based laptop from network as well. Just like Linux, Windows 11, in this case, has a native fax and scanner application and it also detected the device right away. I did a quick test print after and it spit out super fast. The size is just right for what I was looking for. It fit the table where my old printer was. CONs: Nothing for now. Here's hoping this one will not give me the same issues that my old printer did. Also hoping the toner cartridge will last longer than the ink jets.
