Rating and Reviews

MFC-L8340CDW is rated 4.8 out of 5 by 6.
Rated 5 out of 5 by from Perfect printer I was so excited to receive my new printer Brother MFC L8340 CDW. I was looking to change my old printer for a while, just couldn't decide which printer to choose. I was very well impressed with everything about this printer. From delivery, it came super fast and it was all packed to how easy it was to install it. I remember with my previous printer, I need it to call the company to get help, with Brother it was all ready in 10 minutes. It even has a QR code that you can scan if you are stuck during the installation. It is a quiet printer, perfect fir the office or for home. I work 3 days from home and I am using it everyday. Quick, easy and efficient, very easy to use. It comes with toners.It can print 30 pages per minute, you can print directly from the desktop wireless also from USB. It has a great design, the screen is 8cm wide, easy to read and use.I couldn't be any happier with my choice of printer and I highly reccomend it.

Rated 5 out of 5 by from Brother MFC-L8340CDW Professional A4 Compact, Colo Luckily I was at home when the printer was delivered because it comes in a large and heavy box to the extent I had to get it myself from the delivery companies van. The printer was well packaged. After opening the box and getting the printer out and placed in it's new home, I sat down and had a look through the manual. After a quick read I plugged it in and followed the instructions to set it up and start using it. Running my own business from home a quality printer is an essential tool for me. I started with the basic just printing out a few letters and invoices. Quick easy and efficient. Next I printed out some double sided fliers once again no problems. Touch screen is big enough to easily read and use. The scanner was great and helped me with the design for my fliers. The quality of the print is excellent and more than meets my needs. All in all I'm extremely happy with my new Brother all in one printer.

Rated 5 out of 5 by from Very Impressed I was very excited to receive delivery of my new printer. My current printer is getting old and very sluggish at printing so I was looking for a new printer that would be quicker and save me time. I unboxed this as soon as it arrived and was pleasantly surprise at how quick and easy it was to set up. I linked it to my phone with the app and printed some documents and photos to test out the quality. It printed in seconds, much quicker than my current printer and the print quality is excellent. If you’re in the market for a new printer then this is one I would highly recommend. A*

Rated 5 out of 5 by from MFC-L8340CDW Colour LED All In One Printer Well packaged from opening the box to starting to print only took me 10 minutes to complete it was easy read user guide with nice clear pictures and a QR code If you get stuck . The 4 toner cartridges are super easy to install, the print quality is fantastic with nice bright clear prints with no colour bleeds also the print time is quick. The LEF screen is over 8cm wide and is easy to read and with back/home/cancel buttons makes it quite simple to select the right program there is also a power button. It’s a well built robust A4 printer that doesn’t take up to much space that prints up to 30ppm on A4 double sided it holds 250 sheets of A4 with a 50 sheet ADF and 512MB memory.Send and receive FAXES with the fax program feature print direct from you phone with the 5G connection I tried the photocopier and as far as I am concerned personally couldn’t tell the difference between the two as they were identical. The scanner works lovely I tried a letter also a picture to compare with and it scanned both of them just like a scanner should nice and clean at a great speed. The printer is not to large it sorts my office well and would not look out of place in a smaller or bigger environment. The quality of the printer in my opinion is fantastic and it meets all my office needs I would highly recommend this printer.
