Summary: An excellent printer as we print nearly 1M pages per year. Currently upgrading from a room full of HP 4350N's to these 4515n's and the first thing you notice is the output tray holds nearly twice as much. Also the speed and paper movement is much faster. I would rate excellent but as what seems to be a trend, the exterior plastic pieces seem flimsy and just does not seem as solid as the 4350's. So far so good on printing, and speed.
