This is a step up the model number earns. The Epson EcoTank ET-2803 and the ET-2850 are both 28-series supertanks — same cartridge-free engine, same refill-from-bottles tanks, same rough two-years-of-ink pitch — but the 2850 is not a relabel of the cheaper one. It adds automatic two-sided printing the ET-2803 makes you do by hand, a higher print resolution, and a faster rated black speed. So the literal pick has a clean answer: print double-sided or want crisper output, and the ET-2850 is worth the jump; print one-sided pages and the ET-2803 saves you money for an everyday-identical result.

That settles the feature question. The cost question sits underneath it, and it cuts the other way. Both printers refill from the same bottle ink, so the running-cost savings that justify an EcoTank are already baked into the cheaper ET-2803 — stepping up to the 2850 buys workflow, not a lower cost-per-page. And both carry the same quiet catch every inkjet tank does: leave it idle and the printhead clogs. Spend a minute on which features you'll use; spend the rest on whether a tank suits how often you actually print.

At a Glance

What the 2850 adds, line by line

On the "At a Glance" table these two read as one EcoTank column with three rows that move. Start there, because those three rows are the whole reason to pay more.

The headline addition is duplex. Epson lists the ET-2850 as having Auto 2-sided printing helps save paper without hand-flipping — the ET-2803 has no auto-duplex, so every two-sided job means feeding each sheet back yourself. The second upgrade is resolution: the 2850 Prints at a 4800 x 1200 resolution, where the ET-2803's print engine is tuned to push pages out faster than to chase fine detail. The third is rated speed — the 2850 Prints up to 10.5 pages per minute in black. Those three lines are the case for the higher number.

Connectivity tilts the same way. Both print over Wi-Fi, but the 2850 casts a wider net — its listing Offers mobile printing options, including the Epson Smart Panel app, AirPrint, Android Printing, and Mopria. The ET-2803 covers the basics — it Features wireless, plus hands-free voice-activated printing through AirPrint and the Smart Panel app — and adds a small color display for on-device navigation, since it's a true all-in-one with a High-resolution flatbed scanner and a color display for easy document copying. Both scan and copy; the 2850 simply reaches more device types out of the box.

So the feature math lands in one line: pay up for the ET-2850 only if you print double-sided or want the sharper output. If you don't, the ET-2803 gives you the same scanning, copying, and bottle-ink economics for less.

The running cost is a wash — and that's the point

Here's the catch the spec gap hides: stepping up to the 2850 does not lower what you spend on ink. Both are cartridge-free EcoTanks, and the cheaper ET-2803 already delivers the savings that justify a tank at all.

The ink case is the same on both machines.

Look at what the ET-2803 already promises. Epson rates its in-box ink so that’s enough to print up to 4,500 pages black/7,500 color, and frames the savings against cartridges directly: No more tiny, expensive ink cartridges; each ink bottle set is equivalent to about 80 individual cartridges. The ET-2850 pours from the same bottle-ink family — so its cost-per-page lands in the same place. Independent testing is what puts that number in context: RTINGS' cost-per-print and page-yield testing measures EcoTank bottle ink many times cheaper per page than cartridge printers, and Consumer Reports' inkjet running-cost testing reaches the same verdict across the supertank class. We lay out exactly how that cost axis gets weighed against the feature axis in our inkjet comparison criteria.

The other half of the value is shared too: freedom from a subscription. Neither EcoTank gates you behind a monthly ink charge — as one ET-2850 owner puts it, No subscription is required, you can just use the ink bottles. The same is true of the ET-2803. After HP's Instant Ink lock-in, that freedom is half the reason owners switch to a tank — and it costs the same nothing on either model. The refillable inkjet printer guide walks through that bottle-ink economics in full.

Then there's the speed both pay for in color. The 2850's rated 10.5 ppm is a black-text number; color and duplex drag. One owner timed double-sided printing if you want a 6 page job to complete within 20 minutes — and twenty minutes is the floor, not the ceiling. The ET-2803 is no faster in color. Neither tank is the machine for someone who needs stacks out fast; both reward patience.

Step-up tank, entry tank, or a laser instead?

Because these two share an ink system and split only on workflow, "who buys which" comes down to one habit — do you print double-sided and care about sharpness — wrapped around a bigger question about whether a tank suits how often you print at all. If you are considering the ET-2803 to save money, be honest about how often you'll flip pages by hand; if you are looking at the ET-2850 for its duplex, know you're paying for the feature, not a lower ink bill. For buyers coming from a cartridge printer, either one ends the cartridge bills and the choice between them is purely workflow. And for anyone switching from an older EcoTank, the 2850 is the closer match to a modern two-sided workflow. For weekly home printing either works; for the lightest users, neither does.

Buy the ET-2850 if…

…you print double-sided, or you want the crisper output. Automatic two-sided printing and the higher 4800 x 1200 resolution are the 2850's whole reason to cost more, and for a home that prints reports, school packets, or anything two-sided they save real time and effort every week. You also get the faster rated black speed. Going in, accept that the ink bill is the same as the cheaper model — you're paying for the workflow, not a cost cut. Our full ET-2850 review covers its real-world setup and the color-speed gripe in detail.

Buy the ET-2803 if…

…you mostly print one-sided pages and want to spend less. With manual duplex and a speed-tuned engine, the ET-2803 is the lighter-duty sibling, and for printing homework, recipes, and the odd color page it delivers the identical bottle-ink savings for less money. Owners who print regularly rate it highly — one calls it the Best mid range tank print for home use. It best suits the household that prints weekly but rarely needs two sides. Read the ownership detail in our full ET-2803 review.

Skip both if…

…you print only a few times a year. The community is blunt on this — If you don't print frequently, inktank printers will get their print heads clogged. Both EcoTanks need regular use to stay healthy, and seasoned owners keep a weekly reminder to run a page and exercise the nozzles. For genuinely occasional printing, a color laser that doesn't dry out is the safer pick.
