The Brother MFC-L3720CDW is a practical color all-in-one for small offices that need more than a basic printer. It combines print, copy, scan, and fax functions, and its automatic duplex printing makes it better suited to office documents than a simple entry-level color printer.

For everyday use, the strongest features are the 250-sheet paper tray, 50-page automatic document feeder, and 3.5-inch color touchscreen. These make it easier to handle forms, invoices, letters, reports, and multi-page documents without constantly refilling paper or navigating a small text-only display.

Connectivity is convenient for wireless offices. The printer supports dual-band Wi-Fi, Wi-Fi Direct, mobile printing options, and USB. However, it does not include Ethernet, so buyers who require a wired network connection should look at a different model.

Performance is well matched to light and moderate office use. Brother lists print speeds up to 19 pages per minute for both black and color, which is enough for many home offices but not especially fast for larger teams. The scanner supports flatbed and ADF scanning, but automatic duplex scanning is not included.

• Choose it for: small-office color documents, wireless setup, fax needs, and multi-page ADF scanning.
• Think twice if: you need duplex scanning, Ethernet, or faster color output for a larger workgroup.
• Toner note: it uses Brother TN229-series toner options, so ongoing supply cost should be part of the buying decision.

Overall, the MFC-L3720CDW is a balanced choice for buyers who want a dependable Brother color all-in-one with business features, as long as they understand its limits around duplex scanning, wired networking, and high-volume speed.
