The Brother MFC-L3770CDW is an excellent color laser printer for home or small offices, but can be a good fit for other uses as well. It has an outstanding build quality that should last for years, and its input tray can hold a large amount of paper, making it a great choice for big print jobs. It prints fast and won't take up too much of your time; however, it may not be the best choice for photo printing, as color accuracy is quite poor and its cost-per-print can rise significantly if you print in large numbers. Nonetheless, it should still satisfy those who mostly print in black.
The Brother MFC-L3770CDW is a mediocre family printer. While it can print in color and its cost-per-print is good, the quality of printed photos is rather poor. Photos tend to look muted and the colors are inaccurate. On the bright side, its scanning resolution and color depth are exceptional, so you can use it to enlarge photos or do some light editing.
The Brother MFC-L3770CDW is an excellent printer for home or small offices. It can print a large number of copies at a low cost when printing in black only, but the cost for color printing can rise significantly. Its build quality is outstanding, and it's equipped with an automatic document feeder that can save you a lot of time. Its printing speed is superb, but its wireless connectivity options are somewhat limited, as it doesn't support Bluetooth or external SD cards.
The Brother MFC-L3770CDW is an okay printer for students. Printing black-only documents in large numbers won't cost significantly more, and it can print very fast, though the first page tends to be on the slow side. You can connect to the printer via Wi-Fi, and its mobile app supports most common file types, but you won't be able to print from an external drive like an SD card.
The Brother MFC-L3770CDW is a great printer for printing black and white documents. Although this printer can print in color, it's much more suited for black only documents, as the cost-per-print remains low even if you print a lot. Printing speed is excellent and it accepts high-yield cartridges, so you won't have to replace the toners as often.
The MFC-L3770CDW is a bad printer for printing photos. Pictures lack detail, the colors are muted, and there's a lot of banding as well. Additionally, its color accuracy is mediocre and it can't print on photo paper.
The Brother MFC-L3770CDW has an outstanding design. It's mainly built with hard plastic that feels solid and sturdy. The input and output trays are well-designed, with sliders that adjust to the paper's format, and the toners are easy to access. The scanner's lid has hinges that can extend vertically to accommodate thicker documents or books; however, the display console is horizontal and can't be adjusted, which can be difficult to see if you're seated or if the printer is placed too high.
The printer is fairly large, tall, and very heavy. Since the display console is horizontal, the printer needs to be on a lower table for better visibility.
The Brother MFC-L3770CDW has an excellent display. It's easy to read and it's touch-sensitive. However, because the display faces upward and isn't adjustable, it can be hard to see if you're seated.
The Brother MFC-L3770CDW has an excellent cartridge system. The toner is separate from the drum unit, so you won't have to replace the drum when you replace the toner. The printer accepts third-party toner, but using them may void the warranty.
The Brother MFC-L3770CDW has outstanding scanning features. The scanning resolution and color depth are good enough for photo scanning, and it has an Automatic Document Feeder, making it easy to scan multiple pages and two-sided documents as well. Additionally, the scanner's lid has hinges that can extend to accommodate thicker documents or books. If you don't need a scanner option, check out the Brother HL-L3270CDW Laser.
Update 06/16/2020: We had previously listed an incorrect price for the black toner cartridge. It has been corrected and the score has been adjusted accordingly.
The Brother MFC-L3770CDW's cost-per-print is excellent. If you print mainly in black, the cost rises slightly as you print over a certain number of pages, but the cost of printing in color rises significantly the more you print. Do note that the cost of the color cartridge includes all three colors, though they can be purchased separately.
Printing speed is great. It takes longer to print the first page, but subsequent pages are much faster.
Printing color accuracy is mediocre. Most colors aren't printed correctly; as such, it's not recommended for photo printing or graphic design.
The Brother MFC-L3770CDW has bad photo printing quality, though still decent for a laser printer. While it can bring out small details, the overall image isn't as sharp and colors look muted and inaccurate. Additionally, there's quite a bit of banding when printing with green and blue. Note that the printer can't print on 4" x 6" paper, so glossy 8.5" x 11" paper was used instead. If you need to print off glossy images with a good amount of detail and vibrancy, the HP OfficeJet Pro 7740 has significantly better photo printing quality.
These results are based on the actual physical photo, not the scanned image provided for reference above, which may not be representative of the printer's photo print quality.
The Brother MFC-L3770CDW's input tray has sliders that adjust to the paper's size up to the legal format. However, it can't print large documents such as tabloid size or small photos.
Update 05/26/2020: This printer does support Wi-Fi Direct. We've updated the review.
The Brother MFC-L3770CDW has decent connectivity. It supports wireless printing from mobile devices such as AirPrint for Apple devices and Mopria for Android devices.
The Brother iPrint&Scan app is outstanding. It supports nearly every file type and you can also scan directly to your mobile device. You can access the printer's settings as well and to check on the printer's ink levels. It also supports NFC, so you can quickly connect your mobile phone to the printer.
The Brother HL-L3270CDW Laser and the Brother MFC-L3770CDW Laser are two very similar printers. They both have outstanding build quality, print fast with a low cost-per-print, but neither is the best choice for photo printing. The main difference is that the HL-L3270CDW doesn't come with a scanner, while the MFC-L3770CDW does.
The Brother MFC-L3770CDW is a much better printer than the Brother HL-L2390DW. The MFC-L3770CDW has the ability to print in both black and white and color, has an outstanding build quality, and can hold a large amount of paper. Neither are good for photo printing, but the MFC-L3770CDW is still decent for a laser printer.
The Brother MFC-L3770CDW Laser is a better printer for office use than the HP OfficeJet 7740 Pro. The Brother is a laser printer, so it can yield even more pages before its toner cartridges need to be replaced, and its print speed is much faster too, although its first black-only page takes a bit longer to get started. However, the HP is more versatile. It has a significantly better photo printing quality, it has a USB port so that you can print directly from your thumb drive, and its overall cost-per-print is slightly lower too. That being said, you'll need to change its inkjet cartridges a bit more frequently though.
