Along with fast speed, the X551dw offers an appropriate level of paper handling, with a 500-sheet drawer, a 50-sheet multipurpose tray, and a duplexer (for two-sided printing) standard, plus an optional 500-sheet drawer ($199 direct) if you need more capacity. As with a laser, the paper comes out face down in the output tray, so documents don't have to print in reverse order for page one to be at the front of the stack.
