Best forAnyone tired of cartridge costs — this is the home-office default in 2026.Home office all-in-one — but ONLY worth it with Instant Ink, otherwise cartridge costs hurt.

Which should you buy?

This is the classic "refillable tank vs cartridge" decision. The HP 9120e is the faster, more office-like printer: 22 ppm, a 35-sheet ADF, duplex scanning, Ethernet. The ET-2850 is slower (10.5 ppm), has no ADF, and looks like a home printer. But the HP's 937 cartridges cost around £100 a set for 800–1,250 pages, while the Epson's 104 bottles cost £30 for 4,500–7,500 pages. Over three years of moderate printing the Epson saves several hundred pounds.

HP's answer is Instant Ink, and it does change the maths — on a plan the 9120e is genuinely economical and you never think about cartridges. If you're happy with a subscription tied to the printer, the HP is the nicer machine. If you'd rather own your printing outright, the EcoTank.
