Conclusion: The HP 4650n is a strong contender, with fast performance for both color and monochrome output, good to excellent output quality, and reasonably heavy-duty paper-handling options. The 1.6-cent cost per monochrome page means you'll probably want it to supplement, rather than replace, a monochrome laser.
Pros: Fast performance. Excellent text quality, near-excellent graphics, and good to very good photos. Options include duplexer and a maximum 1,600-sheet paper capacity.
Cons: Claimed 1.6-cents per monochrome page is higher cost than for an equivalent monochrome printer.
