The key feature of the $1699 EcoTank Pro ET-16600 is implied by its name. Printers in the EcoTank range all feature built-in ink tanks that can be cheaply refilled from bottles, lowering the cost per page and reducing plastic waste.
The ET-16600 is supplied with enough ink to print up to 4500 pages in black and 2800 pages in colour, though that depends on the content of the pages and how frequently the printer is used.
Replacement ink bottles are priced from $24.99 and contain enough ink for up to 7500 mono pages or up to 6000 colour pages.
Specifications include 4800dpi printing and maximum print speeds of 25ppm for mono and 12ppm in colour. Automatic double-sided printing and copying is supported, a feature that can further reduce both running costs and the amount of paper that ends up in waste or recycling bins.
Epson has not skimped on paper capacity, with dual 250-sheet trays and a rear feed tray for specialty media.
The maximum paper size accommodated is 13x19in (330x482mm), which is slightly larger than A3 (297x420mm), hence the A3+ designation.
The A3 scanner works at up to 2400dpi and has a 50-sheet duplex automatic document feeder, which is another convenience feature.
Like most printers today, the ET-16600 includes Ethernet and Wi-Fi (802.11n) interfaces, with support for printing from computers and mobile devices (including via AirPrint and Google Cloud Print).
Fax capability is included, and features the ability to store up to 180 pages in memory and to send colour faxes from computers without first making a paper copy.
