Rated 5 out of 5 by from Preis und Leistung super! Früher einen Brother besessen, war prima. Danach Canons und Epson, mit beiden nicht wirklich zufrieden da zu teuer und qualitativ nach meinem Empfinden schlechter. Nun wieder Brother-was für ein Unterschied. Ich bin sehr zufrieden, due Nutzung des Gerätes macht förmlich Freude!

Rated 4 out of 5 by from Fantastic All-In-One printer Purchased just over a month ago, for home use, space limited at present, however the unit is small, light and fits where my older refurbished printer (thank you printer) of 20+ years was sited at present. The Brother MFCJ4340DW is efficient has useful software that is easy to utilise for both black&white and colour prints. Set up out of the box is simple. Take clear photos of the serial numbers and ID first before set up and final location of the printer. Cable management (power and USB) is easy and works surprisingly well, I utilised the USB connection (used my existing USB cable) .Print speeds compared to older previous printer are fast acceptable and a delight, both mono and colour print(s) quality and legibility are fine, even at small font size, and very acceptable for our use and meets expectation. Colour prints on normal A4 80gsm really look good (form me!) used one specific colour photo paper and the result was good. Also used thicker photo greeting paper and using publisher the results were fine.I experience one paper jam (A4 caught) possibly how i placed the paper and tweaked print options while running some tests. However the paper jam and was easily cleared removed) Thus far no issues or problems Scanning (TWAIN drivers) worked well , shame no duplex, perhaps i have yet to discover how duplex scanning works. For duplex scans i manually return paper to scan second side at present.Scans acceptable quality and speed and saved to PDF.. However duplex printing is available and works well, with multiple modes , booklet single sided etc. Prints in both mono and colour benefit from range of eco, normal,high or best final quality prints. Still discovering the various parameters and print scan options, fax is available and i have yet to use this option. Printer cartridges that included in the box still going strong, software utilities provide usage stats as a guide. Software, driver updates can be automated and also a lot of useful information on the site for this printer model. This printer model fits a specific budget and usage requirements, the unit build is reasonable and with care should last long time. The extended catch fro prints is wee bit light but again for the price range and with care works. This printer offers a range of print options the normal naturally works well, i have used the eco mode for some PowerPoints and other page configurations and results are more than acceptable. There is a small on screen management (no touch screen at this price point) work for me.
