Epson EcoTank Photo ET-8550

The ET-8550’s headline number is what it costs to print a photo. Epson puts it at roughly 4 cents for a borderless 4×6, against about 40 cents on a cartridge photo printer — that one is Epson’s own published figure rather than ours, because a six-ink photo print isn’t something the ISO page-yield maths behind our other numbers can model. Because it’s a refillable supertank fed from Epson 552 bottles, that low cost holds across its six inks, and plain-paper documents stay tank-cheap too — about 0.36 cents for a black page and roughly 1.42 cents for a color graphics page. As with all supply costs, these move over time, so verify before you buy.

It scores a notch below the pure office tanks on this measure, not above them, for a simple reason: a six-color photo system uses more, and more specialized, ink than a four-color document printer, so its cost-per-page — while excellent by any normal standard — isn’t quite the rock-bottom of an ET-4950. Judged as a photo printer, though, its running cost is in a different universe from cartridge rivals, which is exactly the point of buying it.

Bottom line on running cost: Photo prints for a few cents instead of dozens, and documents still tank-cheap. A hair behind the four-color office tanks on plain paper, but transformative next to any cartridge photo printer.

This is the best-scoring category on the best-scoring printer for image work in our guide. The ET-8550 uses a six-color ink set — cyan, magenta, yellow, a standard black, plus a dedicated photo black and a gray — and that extra pair is what separates it from an ordinary office printer. The gray in particular produces smooth, neutral black-and-white photos and clean gradients without the color-tinting that plagues printers relying on mixed CMY for gray tones. Output goes up to 5760 × 1440 dpi across media as wide as 13 inches.

The result is genuinely gallery-capable color and mono photography, plus crisp, professional documents when you’re not printing images. For a home office that produces client-facing prints, artwork, or family photos alongside its paperwork, this is the highest print quality available anywhere in our rankings — and it earns our top quality score.

Bottom line on print quality: The highest in the guide. A six-color system with dedicated gray and photo black delivers gallery-grade photos and wide-format output, while still printing sharp everyday documents.

For a photo-oriented machine the ET-8550 keeps up well on documents, rated at about 16 pages per minute in black and 12 in color, with automatic two-sided printing. Photo output is necessarily slower — high-quality borderless prints take their time, as they do on any photo printer — but that’s expected and not what you buy this printer to rush.

Paper handling is built around versatility rather than volume: it accepts wide-format media up to 13 inches, has front and rear feed paths for different stocks, and even prints directly onto discs. What it lacks is a document feeder — every copy or scan is placed on the flatbed one sheet at a time — which is a real limitation for anyone doing multi-page paperwork, and part of why this is a photo specialist rather than an office workhorse.

Bottom line on speed & paper handling: Solid document speed and auto-duplex, with standout wide-format and specialty-media support. No ADF, so multi-page copying and scanning is one sheet at a time.

This is the ET-8550’s weakest category, and the reason is straightforward: it’s designed as a photo printer, so it omits the automatic document feeder and fax that a full office all-in-one includes. It prints, scans, and copies, but the missing ADF means it can’t batch-scan or batch-copy a stack, which a paperwork-heavy office will feel.

What it does have is genuinely good. A large 4.3-inch color touchscreen makes photo selection and editing easy, there’s an SD card slot for printing straight from a camera card, disc printing for labeling CDs and DVDs, and the full connectivity suite — Wi-Fi, Wi-Fi Direct, Ethernet, and USB — plus mobile printing. If your priority is images rather than office automation, the feature set is well-judged; measured against a fax-and-ADF office machine, it scores lower here by design.

Bottom line on features & connectivity: Great photo-focused extras — big touchscreen, SD slot, disc printing, full wired and wireless connectivity — but no ADF or fax, which caps its score against full office all-in-ones.

Like every EcoTank, the ET-8550 is refilled from standard Epson 552 bottles rather than cartridges, so there’s no chip to authenticate and no firmware behavior that restricts your supplies — the low per-print cost is straightforward and durable. This is the supply-flexibility dimension our framework scores on its own, and a bottle-fed tank sits at the top of it.

On reliability, Epson’s EcoTank line has an established track record, and the six-color system is well proven in this and the related ET-8500. As with any photo inkjet, running an occasional print keeps the six channels flowing and the head healthy — a non-issue if you print regularly. It carries a one-year limited warranty, standard for the category.

Bottom line on consumable freedom & reliability: Refillable six-color tanks mean no cartridge lock-in and a durable cost advantage, backed by Epson’s proven EcoTank reliability.

The ET-8550 is one of the more expensive printers in our guide to buy, and that premium up-front price is why it scores in the middle here rather than at the top. It’s also the only way to get its combination of six-color photo quality, wide-format printing, and supertank running costs in one machine — so the question is whether you’ll use those strengths.

If you print photos or wide-format work with any regularity, the math favors it quickly: the per-print savings over a cartridge photo printer are large, and they compound. If you only ever print documents, you’re paying for photo capability you won’t use, and a cheaper office tank like the ET-4950 is the smarter value. It carries a one-year limited warranty, standard for the class.

Bottom line on value & warranty: A premium purchase price that pays back fast for photo and wide-format users, but overkill if you only print documents. Standard one-year warranty.
