Our Verdict
HP OfficeJet Pro 6978
Epson WorkForce Pro WF-3820
The HP OfficeJet Pro 6978 and the Epson WorkForce Pro WF-3820 are inkjet printers designed for home offices, but the Epson performs better overall. The Epson can print more pages before its cartridges run out, saving you more money in the long term. Also, it prints much faster, even if you're just printing out one page. On the other hand, the HP's ADF can automatically scan double-sided sheets, and it also produces slightly higher-quality documents and scans.
