Our Verdict

Epson EcoTank ET-2850

HP OfficeJet Pro 9135e

Although both are all-in-one inkjet models, the HP OfficeJet Pro 9135e and the Epson EcoTank ET-2850 are very different. The HP is a more office-oriented printer with features like an automatic feeder, duplex scanning, and Ethernet connectivity. It also produces sharper documents and prints faster. On the other hand, the Epson has a wider color range and a higher print resolution, allowing it to produce more detailed and colorful photos. The Epson is also a supertank model that yields significantly more prints, making it cheaper to maintain.
