Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer Review: The Home Office Workhorse We’ve Been Waiting For?

There’s a familiar story in many modern homes, one that often ends in frustration. It begins with the need to print a single, urgent document—a shipping label, a child’s homework, a signed contract. You send the job to your old, cheap printer, only to be met with blinking error lights, cryptic “out of ink” messages despite just changing the cartridge, or a paper jam so deep it requires a degree in mechanical engineering to resolve. For years, I navigated this landscape of disappointment, treating my home printer as a necessary evil. With the shift to hybrid and remote work, this occasional annoyance became a daily bottleneck. The demand for a reliable machine that could not only print quickly but also scan multi-page documents and make clean copies became non-negotiable. The search was on for an all-in-one device that wasn’t just a box of compromises, but a genuine productivity tool. This is the very problem the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer aims to solve.

What to Consider Before Buying an All-In-One Printer

An All-In-One Printer is more than just an item; it’s a key solution for consolidating your office needs into a single, efficient footprint. It solves the clutter of having a separate scanner, copier, and printer, saving valuable desk space and streamlining your workflow. The main benefits are convenience and cost-effectiveness. Instead of buying and maintaining three different devices, you have one central hub for all your document management tasks, from printing vibrant colour presentations to digitising a stack of receipts for your expenses. It’s about reclaiming time and reducing complexity in your daily work or home life.

The ideal customer for this type of product is someone running a small business from home, a remote worker with varied document needs, or a family with students who need to print, scan, and copy assignments. They value efficiency, reliability, and sensible long-term running costs. Conversely, this type of printer might not be suitable for those who need professional-grade photographic prints, as dedicated photo printers offer superior colour accuracy and media handling. It’s also not designed for high-volume corporate environments that might print thousands of pages a day; for that, a larger, more robust laser printer would be a better investment.

Before investing, consider these crucial points in detail:

• Dimensions & Space: All-in-one printers can be surprisingly bulky. Before you buy, measure your intended space carefully, accounting not just for the printer’s footprint (34.3 x 43.5 x 18 cm for this model) but also for clearance to open scanner lids, extend paper trays, and access ink cartridges. A compact design is great, but not if it’s a struggle to perform basic maintenance.
• Capacity/Performance: Look beyond the initial price tag to the performance specs. Key metrics include print speed (PPM – pages per minute), the capacity of the paper tray (this Brother holds 150 sheets), and whether it has an Automatic Document Feeder (ADF) for multi-page scanning. Automatic duplex (two-sided) printing is another essential feature that saves paper, time, and money.
• Materials & Durability: The build quality tells you a lot about a printer’s expected lifespan. Look for sturdy plastics that don’t feel flimsy or creak under pressure. A well-constructed paper tray and a solid scanner lid hinge are good indicators of a durable machine designed for regular use rather than occasional printing.
• Ease of Use & Maintenance: A printer should simplify your life, not complicate it. Consider the setup process, the clarity of the control panel, and the quality of the companion mobile app. Most importantly, research the cost and yield of replacement ink cartridges, as this is the biggest long-term expense. A printer with high-yield cartridge options will almost always be more economical over time.

Keeping these factors in mind, the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer stands out in several areas, particularly in performance and long-term value. You can explore its detailed specifications and features here.

While the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Solid, Sensible, and Ready for Business

Unboxing the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer, the first thing we noticed was its reassuring heft and solid construction. Weighing in at 8.8 kg, it feels substantial, not like the flimsy, feather-light printers that dominate the budget end of the market. Several users noted that “nothing rattles or wobbles,” and our experience confirmed this; the build quality inspires confidence from the get-go. The design is clean and professional in a matte white finish that fits neatly into a modern office environment without being obtrusive. While one user wished for a black option, we found the white design to be bright and practical.

The control panel is straightforward, featuring physical buttons alongside a small colour LCD screen. This is a point of contention for some; we, like one reviewer, would have preferred a larger touchscreen for easier navigation, especially when typing in a long Wi-Fi password. However, the physical buttons are responsive and the on-screen menus, guided by the display, are logical and clear. It’s a functional, no-nonsense approach that prioritises reliability over flashiness, a theme that carries through the entire user experience.

Deep Dive: Putting the Brother MFC-J4340DW to the Test

A printer’s true worth is revealed not on the spec sheet, but in the day-to-day grind of a busy home office. We spent weeks using the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer as our primary device, throwing everything at it from multi-page reports and colour brochures to stacks of documents for scanning. It’s here, under pressure, that this machine truly begins to shine, proving itself to be less of a simple peripheral and more of a reliable office partner.

Setup and Connectivity: From Box to First Print in Minutes

Brother has absolutely nailed the setup experience. Many users, including those who confess to being “often desperate” with printer setups in the past, called the process a “child’s play,” and we wholeheartedly agree. From the moment you power it on, the 4.5cm colour LCD screen comes to life and walks you through every single step. There’s no ambiguity. It instructs you on how to unbox and gently shake the ink cartridges before inserting them into their clearly marked, front-facing slots. The cartridges click into place with a satisfying certainty.

The next step, connecting to our Wi-Fi network, was the only minor hurdle. As one user noted, typing a complex password using the directional arrow buttons and an on-screen keyboard is clumsy compared to a touchscreen. It’s a one-time inconvenience, but it’s noticeable. Once connected, however, the connection proved to be rock-solid. We never experienced a single dropped signal or “printer offline” error during our testing period. The real magic happens when you pair it with the Brother Mobile Connect app. We installed it on both Android and iOS devices, and the app immediately found the printer on the network. Within minutes, we were printing documents directly from our phones, scanning to cloud services, and checking ink levels remotely. This level of seamless mobile integration is what modern users expect, and Brother delivers flawlessly. For anyone tired of wrestling with drivers and network configurations, the remarkably simple setup of this printer is a massive selling point.

Performance and Speed: A True Office Assistant

In a busy work environment, speed matters. The Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer boasts speeds of up to 20 ppm for black and white and 19 ppm for colour, and our real-world tests showed these figures are not just marketing fluff. A 15-page text document was completed in under a minute, with sharp, crisp text that rivaled a laser printer. Colour presentations were also produced swiftly, with vibrant, well-saturated colours. While one user felt the colour quality didn’t quite match their old HP for photos, we found it more than adequate for business graphics, charts, and school projects. For professional photo printing, you’d look elsewhere, but for everything else, the quality is excellent.

Where this machine truly transforms from a simple printer into a productivity powerhouse is with its business-centric features. The automatic duplex printing worked perfectly every time, effortlessly printing on both sides of the paper without a single jam in our testing of over 100 duplexed pages. This is a crucial feature for saving paper and creating professional-looking reports. Even more impressive is the 20-sheet Automatic Document Feeder (ADF). We fed it a stack of invoices, and it scanned them into a single PDF with impressive speed and accuracy. The ability to load a stack of papers and walk away is a game-changer compared to lifting a scanner lid for every single page. It’s this combination of speed and automation that makes the MFC-J4340DW a genuine workhorse.

Ink Efficiency and Long-Term Value: The INKvestment Tank Advantage

Perhaps the most compelling reason to choose the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer is its approach to ink. Many of us have been burned by the “razor and blades” model, where a cheap printer leads to exorbitant costs for tiny ink cartridges. Brother’s INKvestment Tank system turns this model on its head. The printer uses high-capacity cartridges (LC426 series) that are rated for up to 3,000 pages for black and 1,500 pages for colour. One user specifically chose this model after researching the cost-per-page ratio and concluded it represented “good value,” a finding we can firmly corroborate.

While the initial starter cartridges included in the box are, as one user pointed out, of a “ridiculous” low capacity, this is standard practice across the industry. Once you invest in the first set of XL cartridges, the long-term savings become immediately apparent. For a home office or small business printing several hundred pages a month, the difference in running costs compared to a standard cartridge-based printer can amount to hundreds of pounds per year. The printer’s LCD also displays a clear page-count estimate for remaining ink, so you’re never caught by surprise. We do heed the advice of one experienced user who noted that inkjet nozzles can clog if left unused, especially black ink. To prevent this, we recommend printing a test page at least once a week to keep the ink flowing smoothly, ensuring the machine is always ready when you need it.

What Other Users Are Saying

Across the board, the feedback for the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer is overwhelmingly positive, confirming our own excellent experience. The most frequently praised feature is the incredibly easy setup process. User after user, some of whom had never set up a printer before, described it as “kinderleicht” (child’s play) and “super easy,” highlighting the clear on-screen instructions that guide you through every step.

Speed and quiet operation are other common points of praise. One reviewer was impressed that “you can barely hear the printer in the same room,” while many others commended its fast output for both black-and-white and colour documents. The long-term value offered by the high-yield ink cartridges is a significant deciding factor for many, with one customer noting they chose this model specifically because the “cost ratio per page vs the cost of replacement print cartridge represented good value.”

However, the feedback isn’t without criticism. The most common complaint is the lack of a touchscreen, with several users finding the button-based navigation “cumbersome” for entering Wi-Fi passwords. Another notable omission, pointed out by a long-time Brother user, is the absence of a USB host port for printing directly from a flash drive. While not a deal-breaker for most in the age of wireless printing, it’s a feature some expect. Finally, one user reported a mechanical failure of the duplex unit after 1.5 years, a reminder that even reliable hardware can have issues, though their device was promptly replaced.

How Does the Brother MFC-J4340DW Compare to the Alternatives?

The Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer excels as a balanced home office workhorse, but the market offers strong competition catering to different needs. Here’s how it stacks up against three popular alternatives.

1. Epson WorkForce WF-7840DTW A3+ 4-in-1 Printer

The Epson WorkForce WF-7840DTW is the choice for users who need to think bigger. Its standout feature is the ability to print, scan, and copy up to A3+ size. This makes it an ideal solution for architects, designers, or small businesses creating their own large-format marketing materials or spreadsheets. It also boasts two 250-sheet paper trays for a massive 500-sheet total capacity and a 50-sheet ADF, out-muscling the Brother in sheer paper handling. The trade-off is a significantly larger footprint and a higher purchase price. If your work is strictly A4, the Epson is overkill, but if you need the flexibility of A3, it’s a powerful and versatile step up.

2. HP Envy 6420e All-in-One Printer

The HP Envy 6420e targets the modern, connected home user with a focus on sleek design and smart features. It’s often bundled with HP+, HP’s smart printing system which includes a subscription ink service (Instant Ink). This can be a cost-effective option for users with predictable printing habits. The Envy has a more minimalist, stylish aesthetic that might blend better into a living space. However, its performance is geared more towards casual use; its print speeds are slower, and its 35-page ADF is smaller than what you’d want for heavy-duty office tasks. If you prioritise aesthetics and the convenience of an ink subscription over raw speed and capacity, the HP Envy 6420e is a compelling choice.

3. Canon PIXMA TS3451 All-in-One Printer

The Canon PIXMA TS3451 represents the budget-friendly end of the spectrum. It’s a simple, no-frills device perfect for students or very light home use where printing is an occasional necessity. It handles basic printing, scanning, and copying well, but it makes significant compromises to achieve its low price point. It lacks an Automatic Document Feeder and automatic duplex printing, meaning scanning multi-page documents or printing two-sided is a manual, page-by-page process. For anyone with even a modest home office workload, these omissions would quickly become frustrating. It’s a solid choice for the occasional user, but those needing the productivity features of the Brother will find the Canon too basic.

Our Final Verdict: Is the Brother MFC-J4340DW Worth It?

After extensive testing, we can confidently say that the Brother MFC-J4340DW A4 Colour Multifunction Inkjet Printer is a superb all-in-one solution for any home office or small business. It masterfully balances essential features, robust performance, and outstanding long-term value. While it may lack the flashy touchscreen of some rivals or the A3 capabilities of pricier models, it absolutely excels at its core mission: to be a reliable, fast, and economical workhorse that gets the job done without fuss.

The combination of brisk print speeds, the indispensable Automatic Document Feeder, flawless automatic duplexing, and the game-changing INKvestment Tank system makes it a standout performer. It tackles the biggest pain points of home printing—speed, convenience, and running costs—with remarkable success. We recommend it without hesitation to anyone who has outgrown their basic consumer-grade printer and needs a serious tool to support their work. It’s an investment in productivity that will pay for itself in saved time, ink, and frustration.
