Epson EcoTank Pro ET-5850 vs Epson WorkForce Pro WF-7840

The Epson EcoTank Pro ET-5850 is a much better printer for almost every use case than the Epson WorkForce Pro WF-7840. While these are all-in-one color inkjet printers, the ET-5850 uses a supertank reservoir, yielding far greater pages. It prints faster and is more color-accurate, and its ADF-equipped scanning processes documents much quicker. However, the WF-7840 is a wide-format printer with an ADF-equipped scanner capable of duplex scanning Tabloid size sheets. Thus, if your workflow requires printing and scanning Tabloid-size documents or photos, then the WF-7840 is the obvious choice.
