Our Verdict

Epson EcoTank ET-2720

HP Smart Tank Plus 551

Overall, the HP Smart Tank Plus 551 and the Epson EcoTank ET-2720 have very similar performance. The Epson has a better display screen, it prints higher quality photos, and its replacement ink is cheaper. However, the HP yields more black and color pages per cartridge.
