Network monochrome laser printer

The HP LaserJet Pro 400 M401DN is a monochrome laser printer built for small workgroups that need automatic duplex output and wired network sharing. It prints black pages at up to 33 ppm with a 1200 x 1200 dpi resolution and holds 300 sheets in its input tray.

Ethernet-only connectivity limits

The sole network interface is a single RJ-45 Ethernet port, so the printer must sit on a wired LAN segment and cannot join Wi-Fi networks or accept direct USB or mobile print jobs without an intermediary print server.

300-sheet paper capacity decides fit

The maximum paper input of 300 sheets determines whether the device can handle your daily print volume without frequent refilling; buyers who need larger uninterrupted runs will need a model with higher capacity trays.

Questions about this item

Is the CF278A model the only version of the HP LaserJet Pro 400 M401DN available?

The part number CF278A identifies this specific HP LaserJet Pro 400 M401DN duplex-network monochrome laser printer.

What does the 33 ppm black print speed mean for daily office use?

The engine prints up to 33 black-and-white pages per minute at 1200 x 1200 dpi, so a 300-page job finishes in roughly nine minutes once the first page exits.

How does the Ethernet connection affect network printing performance?

The RJ-45 Ethernet port provides wired network integration; actual throughput depends on your switch and cabling, not on the printer alone.
