Our Verdict

Epson EcoTank ET-4700

HP Smart Tank Plus 551

The Epson EcoTank ET-4700 is a slightly better printer than the HP Smart Tank Plus 551. They both have excellent cost-per-prints and high yields for black and color documents like most supertanks. The Epson has a better display screen and the scanner has an Automatic Document Feeder.
