Conclusion: The HP Color LaserJet 3550n is a reasonably capable color laser for those who value output quality more than speed. Both the 16-page-per-minute engine rating and the actual performance are slow for the price. But quality across the board is better than for most color lasers.
Pros: Output quality ranges from the high end of good to excellent. Standard 350-page capacity with 850-page maximum. Easy network installation.
Cons: The 16-page-per-minute engine rating is slow for the price, and so is the measured performance. Network connection uses an external print server.
