Our Verdict

Brother MFC-L3770CDW Laser

Brother MFC-J6945DW

The Brother MFC-J6945DW and Brother MFC-L3770CDW Laser are both amazing printers for small or home offices, but the J6945DW is an inkjet that can scan and print 11" x 17" tabloid-format sheets, while the L3770CDW uses laser technology to print. The J6945DW has higher page yields, lower cost-per-print, and it prints far better-looking photos. Also, its flatbed scanner is larger. On the other hand, the L3770CDW prints much faster.
