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. It got a little banged up and I thought that would be the end of it. Not true, it just keeps on putting out great prints. It is my favorite printer of all time!!
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. Also it reports "out of ink" on cartridges that clearly have a lot of ink in them. I have wasted too much time and nearly missed too many deadlines dealing with this printer's issues before I could get my pages.
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. HP Greed has taken over. I cannot afford to replace that double-sized black ink cartridge every 6 months, and I should not have to. There is absolutely nothing wrong with it.
Summary: These printers are used at work. I bought this third one mainly to keep from having huge inventories of different print cartridges. So I paid too much for this guy but it is worth it to keep inventories of inks down. The K550 has been a good reliable model for us. Just beware when purchasing; I didn't fully understand that I was buying this without the print heads (my fault?), and they are expensive. The ink is not cheap either. But I do like the printer!!!
Summary: Seller knows that they are selling an item which does not work. I asked in advance if it had good print heads. I was assured it did. Then told I would have needed to pay big dollars to get a working model. It says "mint" in box. That usually means it actually works and has working heads. The seller knew what he was selling and still claimed it was "mint". I would never do business with this seller again. He is a knowledgeable vendor, not a home user.
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. D) The inks are expensive. E) The printheads are expensive (and why do you need to replace them? - the printheads of all my Epson printers never need any replacement).
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. The best $50 (uncluding printhead and black ink) I've ever spent. The only issue I have is that the paper is a little clunky to load as it is covered by the output tray.
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 operating function unless I purchased a very expensive printhead. So I did it, ONCE. And it worked fine for a few weeks but then failed again.

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. I called HP and they immediately sent me a replacement unit.
