Summary: I have had a 2550L for several years and it has been fabulous, the best printer I ever purchased. However, HP in their latest printer updates, made it so this product will NOT work. As of 11/1/2012 HP has stated..
Summary: This machine is so loud you could hear it from space. And it's slow. Can't say anything good about it. Please don't waste your money. I won't buy a HP printer again. Everyone I've had has been completely useless.
Summary: What a piece of you-know-what. I really wish I would have done my research before buying this printer. The consumables are VERY expensive, and like the others have said - it's clunky and noisy. Anyone giving this printer more than two stars has to be out of their mind. What a waste of money!
Summary: Has great output, but after 14 months (just out of warranty) and only 5500 color pages printed (and over $350 in consummables), this thing suddenly has broken -- the carousel is apparently a weak point, a common breakage, and it costs as much to fix as to buy a new one. Appalling.
Summary: I'm wishing I had read a few of these reviews in advance of our purchase of the HP 2550 nine months ago. I'll simply reiterate what several reviews have already mentioned - reasonably priced machine ($499), BUT, my small organization doesn't do a huge amount of printing, and we now have to replace...
Summary: I live close to h/p in silicone valley. I would really get a kick out of driving down and walking into the main office and smashing this pos on their floor. Eats toner/ loud as hell/james all the time, try to print on legal size paper.... forget it.I guess people live and learn.
Summary: Wish I could give this printer zero stars. I have had the HP2550L for 15 months. It is not working at the moment because it needs a third imaging drum - at a cost of approximately $180.00 and two toner cartridges.
Summary: If you use a Mac, I advise you not to purchase this printer. In spite of the supposed support for OS X, most of the features of this printer are not available, as HP has not bothered to make the toolbox available for the Mac.
Summary: this printer is horrible. while the color on the pictures come out alright (though not nearly as perfect as i would want it to be), it can't even feed cardstock or envelopes. it gets stuck each time!!!
Summary: As other reveiwers have noted, the smart chips inside the toner cartridges are anything but. They generally force you to toss perfectly good toner catridges and imaging drums away before they're even near empty.
