Combining a truly multifunctional device and a compact but robust shell - the MFC-J4340DW really is the perfect home office business partner.

Work connected, always

You don't just need to be sat at your desk, or even near the printer to use the MFC-J4340DW. With the range of connectivity options available, you can print anywhere in your house or office - and even from your mobile phone. By downloading the Brother Mobile Connect app you can access an array of features - from sending print jobs, to checking your ink levels and ordering replenishments when necessary.

Keep on top of your ink useage, quickly and easily

We've reengineered our ink cartridges to hold more ink and created an internal ink storage tank that delivers more pages of uninterrupted printing without sacrificing the compact, desktop size. Also, thanks to the page gauge feature you can check remaining ink levels on your LCD display to help avoid interrupted printing.

Let the device do the work

If you're working on large documents, these multifunction devices give you the opportunity to print focus on your work while it processes your documents. Whether it's printing double sided automatically, thus saving the environment and paper, or using the automatic document feeder for multipage scanning it's sure to improve your efficiency.

Professional print quality from the comfort of your home

Your workplace may be at home but that should not mean print quality should be compromised. With the MFC-J4340DW you can expect print quality of the highest order, at quick, hassle-free speeds.

Scanning technology to improve work flow, even when working remotely

As a multifunction device this machines does so much more than print. The scanning opportunities available for example can significantly enhance your productivity from home. You can scan in colour or mono at high speeds to several destinations to boost workflow:
