Our Verdict
The Epson EcoTank Pro ET-5850 is a good printer for home use, but it's not its intended purpose. It's very big, which makes storing it a hassle. That said, it prints sharp-looking documents and good-looking photos. Its photos aren't particularly color-accurate, but they're fine for casual photo printing. Its feature-rich scanner offers great versatility, from scanning long documents with its ADF to digitizing material from textbooks thanks to adjustable flatbed hinges; however, scan quality is only okay. Scans tend to look oversaturated and lack some fine details. However, on the bright side, this printer supports a wide range of connectivity options, making it convenient and easy for the whole family to use.

The Epson EcoTank ET-5850 is a decent option if you want a printer that requires minimal maintenance and is always ready to print when needed. Like other inkjet models, it can clog if left unused, so regular printing is recommended to keep the printheads clear. Although the printheads are not replaceable, the high flushing volume helps resolve most clogs without requiring an ink refill. Its large ink tanks provide outstanding page yields, making it a very cost-effective choice. It's also quick, especially compared to most other EcoTanks, which tend to be slower performers.

The Epson EcoTank Pro ET-5850 is good for casual photo printing. While this printer has a fairly wide color gamut, capable of reproducing saturated tones and hues, its color accuracy is only okay and not suitable for use in a professional environment. Despite some graininess, photos look great for at-home use. The cost-per-print is superb thanks to this printer's refillable ink tank system, which yields thousands of prints. Finally, there's wide support for photo paper sizes.

The Epson EcoTank ET-5850 boasts an exceptional page yield, similar to other supertank printers in this line. It's an ideal choice for those with high printing needs.
- Superb page yields and cost-per-print.
The Epson EcoTank Pro ET-5850 offers a feature-rich scanner. Its ADF is capable of double-pass duplex scanning for processing long, double-sided documents, and the flatbed scanner's hinges are slightly adjustable to accommodate larger items, such as textbooks or magazines. As for the scan quality, it's just okay. Text is clear, and colors are vibrant, but the image processing is too aggressive in trying to remove artifacts; it also removes background and fine elements like lines on a graph or watermarks.

Popular Printer Comparisons
The Epson EcoTank Pro ET-5850 is an outstanding all-in-one supertank printer for small or home offices. Its supertank ink system has incredible page yields and a very low cost-per-print. Compared to most other supertank printers we've tested, it prints very quickly, and its photo printing speed is especially impressive. That said, this isn't the best choice for photo printing; while the photos look detailed, they're not color-accurate enough for professional photo printing.

The Epson EcoTank ET-4950 and Epson EcoTank ET-5850 have similar capabilities, but the ET-5850 is better suited for larger workloads. While their print capabilities and page yields are similar, the ET-5850 is much quicker, and its input drawers have much larger capacities.
The Epson EcoTank Pro ET-5850 and the Epson EcoTank ET-15000 are all-in-one color inkjet printers with supertanks, but the ET-5850 is better for small or home offices. The ET-5850's ADF supports duplex scanning, it has a much larger input tray capacity, and it prints significantly faster. On the other hand, the ET-15000 can print on wide tabloid-format paper for specialty prints, and it has much better page yields and cost-per-print.
The Brother MFC-L8930CDW and the Epson EcoTank Pro ET-5850 are both high-end printers designed for small offices. The former is a laser printer while the latter is an inkjet supertank. The Brother is better for offices that only print documents. It's much quicker at both scanning and printing, and you won't have to deal with clogging even if you leave the printer unused for a long time. Its documents are also sharper overall. That said, if your office does need to print photos, the Epson is a better choice, as inkjets are much better suited for this type of workload.
The Epson EcoTank Pro ET-5850 is a much better printer overall than the Lexmark MC3426i. While both are designed primarily for office use, the Epson is an inkjet with a supertank reservoir, and the Lexmark is a color laser printer. Owing to its reservoir, the Epson yields significantly more pages than the Lexmark and has a lower cost per print. The Epson is also more versatile, as it's well suited to printing photos, which all laser printers struggle with due to poor color accuracy. Print speed is almost identical with these printers; however, the Lexmark is slightly better built overall.
