Summary: Was sold as brand new unused...had over 5000 prints on it with the print heads and ink expired in 2008 and empty on 2 colors of ink the printer would not print or function because everything was expired!!!!
Summary: I feel compelled to write a review on this printer even though I have had it for over 6 years! I've never had a single problem with this printer. In fact, when it was brand new, I ran into the cord and it pulled the printer off my counter and it fell 3 feet onto a cement floor.
WHY didn't I read the HP K550 reviews before I bought?!

Summary: Unlike many of the other customers my Yellow/Black printhead worked fine when I got it. My faults with this printer is how fast it goes through the overpriced ink and printheads. The heads require frequent cleaning, which goes quickly through the ink.
Summary: If the overall issues with this printer were not enough (and I was one of the lucky ones who has had very few technical problems with my K550)... the latest drivers are aggressively expiring HP ink cartridges that are perfectly good, relatively new and still plenty full of ink.
Summary: From day one of owning this printer I knew I had made a big mistake. A) It is very loud. B) It consumes a lot of time making noise calibrating something, testing something, spitting out pages that aren't printed. C) When you run any of the self diagnostics, it consumes a lot of paper, ink, and time.
Summary: I found this printer lounging around a Salvation army thrift store for $15. When I brought it home I noticed it was printing poorly. The driver diagnosed a bad black/yellow printhead. I orderd a new one and this thing has been printing fantastically ever since.
Summary: I purchased this printer new a couple of years ago, and was generally very satisfied with it. UNTIL, it started developing printhead problems. Despite all the troubleshooting information that HP provides with its Toolbox, and after many hours of work, I was unable to restore the printer to normal...

Summary: I am sitting here spending more time on this printer because it is more important for me to take away money from HP than do something else in my life. This printer, when I first received it, was giving me print head errors when I first got it.
