Overview
Not an all-in-one, this HP LaserJet Enterprise M406dn is a print-only mono laser that watches memory activity to stop attacks and checks firmware at startup. It handles automatic two-sided printing and connects by Ethernet or USB.
Security checks and quick first pages suit a team that shares one printer, with HP Roam for Business reducing wasted supplies. The limit is function, since the listing shows print only and a modest tray stack.
Who it's for
Offices that print contracts and reports over a network and care about security are the target. Home users and buyers who need a multifunction unit should choose a smaller or all-in-one model.
Pros and cons
- Memory monitoring detects attacks
- Firmware checked at startup
- Automatic two-sided printing
- Three paper trays
- Print only, no scan or copy
- Starter cartridge is small
- Modest paper capacity
Performance notes
The laser engine sets the page rate, and the short first page time helps one-page jobs. Duplex printing runs inside the machine. Original HP cartridges with JetIntelligence are named for sharp text and bold blacks.
