It is rightly pointed out that a stripped-down version of the HP Laser Jet Pro 400 M401dn Printer, the HP Laser Jet Pro 400 Printer M401n leaves out the dn model`s duplexer (for two sided printing) as well as its touch screen controls, support for Web apps and ability to print files from a USB
On its positive end; you will appreciate the high quality text; total 300-sheet capacity standard with 50-sheet multipurpose tray
You won`t find duplexer; even as an option
