The EcoTank ET-16600 has the full connectivity suite — USB, Wi-Fi, Ethernet, and Wi-Fi Direct

Unlike the lower-end EcoTank models, the ET-16600 includes an Ethernet port alongside USB 2.0 and Wi-Fi. Wi-Fi Direct rounds out the package for peer-to-peer printing. If you need both wired and wireless options without compromise, this is the EcoTank to pick.
