Epson WorkForce WF-3640 Printer Driver Windows, Mac

Description : Epson WorkForce WF-3640

Paper handling is one of the WF-3640's strongest points. The ample 500-sheet paper capacity is divided into two 250-sheet drawers, making it easy to keep two kinds of paper loaded and switch between them. Beyond that there's a single-sheet manual feed, so you can use a third type of paper without having to swap out paper in either tray, and a built-in duplexer for two-sided printing.
