The Lexmark MS431dw, at up to 42 ppm versus 29 ppm for the HP. Its first page comes out in as fast as 5.9 seconds against 7 seconds for the HP.

Is the Lexmark worth the extra $130?

Only for heavy printing. The Lexmark adds speed, a 550-sheet tray and 20,000-page toner options. If you print a few hundred pages a month and need to scan, the HP covers more for less.

Which holds more paper?

The Lexmark, with a 550-sheet main tray and an optional second 550-sheet tray. The HP holds 150 sheets.

Do both print double-sided?

Yes. Both have automatic duplex printing, so two-sided documents come out without flipping pages by hand.

Which is cheaper to run?

The Lexmark's Extra High Yield Unison toner is rated up to 20,000 pages, which usually lowers cost per page on high volume. The HP suits lighter volumes; check current toner prices on both before deciding.
