Conclusion: The HP LaserJet 2420dn's scores for performance and quality are among the best for any monochrome laser we've tested. But although it includes a duplexer, it comes up short on paper-handling.
Pros: Fast performance. Duplexer and Ethernet card included. Excellent text quality. Better quality graphics than most monochrome lasers.
Cons: Relatively modest paper handling, with a default 350-sheet input capacity, a maximum 850 sheets, and no additional paper-handling options.
