If you've ever needed to print at 13×19 inches — architectural drawings, real estate marketing sheets, event posters, design mockups — you know the frustration of being limited to standard 8.5×11" on a home printer. The Epson WorkForce WF-7840 solves that problem at a price that actually makes sense for small studios and home offices. There is literally no other consumer all-in-one printer that handles wide-format printing this completely for under $300.
Who Needs the WF-7840?
The WF-7840 has a very specific target user: someone who regularly needs to print at tabloid (11×17") or super-B (13×19") size and doesn't want to pay $800+ for a professional wide-format machine. Architects printing site plans, real estate agents producing property flyers, graphic designers reviewing print mockups, photographers wanting large borderless prints — these are the people for whom this printer was built. For anyone just printing standard letter documents, this is overkill. But for wide-format users, it's a revelation.

Print Quality at Wide Format
Using Epson's PrecisionCore printhead technology, the WF-7840 delivers genuinely impressive output at 13×19". We printed architectural floor plans, color presentation boards, and photo enlargements — all with sharp detail and accurate color. At 4800×2400 dpi, fine lines and gradients reproduce cleanly. Photo output on Epson premium glossy paper is excellent, with smooth tonal transitions and vibrant saturation. For professional-quality proofing, this printer punches well above its price class.
Standard 8.5×11" and 11×17" prints are equally sharp. The PrecisionCore technology uses a fixed printhead (not moving piezo-array) that enables more consistent output across the entire print surface — this matters especially at larger sizes where lesser printers show banding or uneven density.
Speed and Practical Throughput
Wide-format printing is inherently slower than standard-size printing — more area to cover means more passes. A full 13×19" color print takes about 2–3 minutes depending on quality settings. For occasional use, this is perfectly acceptable. For someone producing 50+ wide-format prints a day, this is a bottleneck. At standard 8.5×11" sizes, the WF-7840 runs at 17ppm black and about 9ppm color — respectable for an inkjet AIO. Auto-duplex works reliably at standard sizes.
Ink Costs
This is the WF-7840's one meaningful weakness. It uses Epson T802 ink cartridges (standard and XL available). High-yield XL cartridges are strongly recommended — the standard cartridges are poor value. Even with XLs, ink cost per standard page is around $0.08–$0.12 for color, which is not cheap. Wide-format color prints naturally use more ink, pushing the per-print cost higher. If you print wide-format constantly, the ink budget adds up quickly. Factor this into your total cost of ownership.
Pros
- Only consumer AIO with 13×19" wide-format capability under $300
- Excellent print quality via PrecisionCore technology
- Full AIO with ADF, duplex, fax — nothing cut
- Handles tabloid (11×17") in addition to super-B
- WiFi and Ethernet for shared use
Cons
- Very large footprint — needs significant desk or shelf space
- Slow for wide-format prints (2–3 min each)
- Ink costs are higher than EcoTank alternatives
- Heavy (21 lbs) — not easy to move
Should You Buy the WF-7840?
Buy it if: You need 13×19" or tabloid printing capability and don't want to spend $800+ on a dedicated wide-format machine. For architects, designers, real estate professionals, and photographers who occasionally need large prints, this is an extraordinary value. There is simply no better option at this price point.
Skip it if: You only print standard letter size — there's no point paying for wide-format capability you won't use. Also skip it if you need high-speed output or very low running costs — for those priorities, look at EcoTank or laser options.
Our Verdict: BEST WIDE-FORMAT UNDER $300
The only all-in-one that handles 13×19" prints without a professional-grade price tag. If wide format matters to you, there's no alternative at this price.

What is the maximum print size for the WF-7840?
The WF-7840 prints up to 13×19 inches (Super-B / A3+ format). It also handles tabloid (11×17"), legal, letter, and all standard sizes. Borderless printing is supported up to 13×19".
What ink cartridges does the WF-7840 use?
Epson T802 series cartridges (black, cyan, magenta, yellow). Always buy XL cartridges — they significantly reduce cost per page. The standard cartridges are poor value for this printer's typical use cases.
Can the WF-7840 scan at 13×19"?
No — the flatbed scanner is standard letter/legal size (11×17" max). The ADF handles standard sizes only. For 13×19" scanning you'd need a dedicated wide-format scanner.
Is the WF-7840 good for photo printing?
Yes, for a 4-color inkjet at this price. At 4800×2400 dpi on Epson premium media, photo output is vibrant and sharp. It's not a dedicated 6-color photo printer, but for proofing and general photo printing up to 13×19", results are excellent.
