Everything below is drawn from two places: Epson’s own product and ink pages, read on 27 September 2026, and arithmetic on those published figures. We have no unit in hand, no lab and no measured print samples, and nothing on this page should be read as though we did.
What it costs to run
The ET-2850 is filled from Epson 502 ink. A epson 502 black ink bottle was listed at $24.99 and is rated at 7,500 ISO pages; each color bottle was $16.99 and rated at 6,000. That works out at roughly 0.3¢ for a black page and 1.2¢ for a four-color one.
That black figure is the lowest of any Epson tank printer on this site. The ET-2800 and ET-2400 take 522 ink, whose black bottle is rated at 4,500 pages against the 502’s 7,500, so their black page lands nearer 0.4 cents instead. The order reverses on color: 502 color bottles are rated lower than 522 color ones, so a heavy color habit narrows and eventually closes the gap.
| If you print | Ink over 3 years | Total with the printer |
|---|---|---|
| 25 pages a month | $3 | $353 |
| 75 pages a month | $9 | $359 |
| 200 pages a month | $24 | $374 |
Supplies only in the middle column; sticker price plus supplies in the right one. Mono pages at the manufacturer’s rated yield and the supply price we read on 27 September 2026. Real cost runs higher because rated yields assume 5% page coverage. The full method.
Read the right-hand column before the middle one. At 25 pages a month the printer is the overwhelming majority of what you spend over three years and the ink is a rounding error — which means the saving over any other machine is also a rounding error. The purchase only starts defending itself somewhere above about 75 pages a month, and it is comfortable at 200.
The duplexer is the reason to pay the difference
Epson lists automatic two-sided printing on this model and does not list it on the ET-2800 or the ET-2400. On a cartridge printer that would be a convenience feature. On a tank printer it is the biggest running cost on the machine, because the ink has become so cheap that paper overtakes it.
A sheet of plain letter paper costs somewhere around a cent. A black page of ink on this printer costs about 0.3 of a cent. Paper is therefore roughly three times the cost of the ink you put on it, and the mechanism that halves your paper use saves about three times what a cheaper bottle would. That is the whole case for the ET-2850 over the ET-2800, and it is a stronger case than the specification sheet makes it look.
| If you print | Sheets saved a year | Paper saved over 3 years |
|---|---|---|
| 25 pages a month | 150 | about $5 |
| 75 pages a month | 450 | about $14 |
| 200 pages a month | 1,200 | about $36 |
Our arithmetic, assuming half your pages belong to multi-page documents that can be duplexed, and a cent a sheet for plain letter paper. Paper prices vary by brand and quantity, so treat this as an order of magnitude rather than a quotation.
Over three years at a moderate volume that is a useful share of the list-price gap between the two models back in your pocket, and you also carry half as much paper home. If every page you print is a single page — a shipping label, a boarding pass, a recipe — none of this applies and you should buy the cheaper printer.
What you give up
No document feeder
Flatbed scanner only. Fine for a page at a time, tedious for a stack. If scanning paperwork in batches is part of why you are buying a printer, the ET-4800 adds a feeder on 522 ink, and the ET-3850 adds one on the same 502 ink as this machine, so its cost per page is identical to the ET-2850’s and you are paying purely for hardware. Our picks with a document feeder cover both.
A list price that flatters the cheaper models
Epson listed this printer at $349.99 and the ET-2800 at $239.99 when we read their pages. That is a real gap, and at low volumes it is a gap the ink will never close. Street prices on EcoTanks move around a great deal, so the honest advice is to check both prices on the day and let the difference decide: inside about fifty dollars, take the duplexer.
One connectivity detail we could not settle
Epson’s product title for this model mentions Ethernet, while the connectivity line we recorded from the same page lists wireless. We have not been able to resolve that contradiction from published material, so we are not going to assert either answer. If a wired connection is the deciding factor for you, confirm it on the current listing before you buy — and note that the lasers with Ethernet are unambiguous about it.
Does it need a subscription?
No. EcoTank models are filled from bottles you buy outright, and nothing about owning one involves a plan, an account requirement or a monthly page allowance. Epson does sell a supply subscription, but it belongs to its cartridge printers, which are a different product line.
Because there is no cartridge, there is no chip for a firmware update to reject. That is the practical reason bottle-fed printers keep coming out on top of the printer DRM question, rather than any particular virtue on Epson’s part — Epson has its own firmware history, which we cover on the Epson third-party ink page.
ET-2800 or ET-2850: the actual decision
These two printers are close enough that the choice comes down to one question: do you print documents, or do you print pages?
- Documents — reports, chapters, contracts, homework packets. Buy the ET-2850. The duplexer pays for itself in paper, the 502 black bottle is cheaper per page, and this is the machine you will stop thinking about.
- Pages — one form, one label, one recipe. Buy the ET-2800 and keep the difference. Nothing about the ET-2850 will ever earn it back.
- Mostly color photographs. Neither. Both are four-color document printers; a six-color photo tank is a different tool, and our photo printer picks say so plainly.
Who should buy something else
- You print fewer than about twenty pages a month, in black. Buy a mono laser. Toner cannot dry out, the printer costs less up front, and an inkjet left idle for months is the likeliest thing on this page to let you down.
- You scan stacks. You want a document feeder, which means the ET-3850 on the same ink, or a laser all-in-one if your scanning is mono paperwork.
- You want the lowest cost per page we have calculated. The Canon MegaTank G3270 came out lower on both mono and color in our figures, and its pigment black smudges less on cheap paper. It does not duplex.
- Several people will share it over a wire. See the connectivity note above, and consider a networked laser instead.
Where it lands
The ET-2850 is the EcoTank we would buy for a household that prints real documents. It has the cheapest black page in Epson’s tank range, the duplexer saves more than the ink does, and the things it lacks — a feeder, a settled answer on Ethernet — are things most homes do not need. If your printing is sporadic and black only, we would still rather point you at a laser, and we would rather say so than sell you the more interesting machine.
