Our Verdict
Brother MFC-J6945DW
Epson WorkForce Pro WF-7840
The Brother MFC-J6945DW offers better performance than the Epson WorkForce Pro WF-7840. Both can scan and print 11" x 17" tabloid-format sheets. However, the Brother is better for small or home offices as it offers significantly higher page yields at a much cheaper cost-per-print and a faster color document printing speed. On the other hand, if you primarily print black documents, then the Epson is a better choice as it prints black text documents much faster.
