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: 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: This printer has provided solid service for a home based business. It is fast with excellent output free of banding in graphs. This is the third of this model printer, all of which are serving me well, and are without the problems stated in other reviews. The first K550 printer I purchased probably has printed over 100,000 pages and the output is excellent, no need to replace printheads yet.
Summary: I shopped around and found most places were selling this same printer for $200+, so buying it from amazon for $139 with free shipping was a good deal. It's heavy and a little bulky, so be sure you have room to store it. This printer is super fast with color and black text (with great ink life thus far), I have not printed any photos from it as it was purchased to make invitations at work.
Summary: I have always been a big advocate of HP printers, as having worked in the printer division, I saw the quality produced (5 years ago perspective). I was very excited in getting the new K550, as I have business needs that this printer should fulfill. Plus, a collegue at HP gave it big reviews. However, there are 2 things I'm finding frustrating. 1) The printer driver on the CD-ROM and HP website (FULL VERSION- 150 MB size) was acting like a VIRUS on my PC!
Summary: En general es un excelente producto.Muy rendidor y con buena realcion costo beneficio
Pros: - La velocidad es bastante aceptable y la calidad de impresion es realmente excelentes. La distribucion de los colores de la tinta es muy util y practico
Cons: - Se dificulta un poco conseguir los cartuchos y aunque hasta ahora no los he necesitado pareceria ser que se dificulta mucho conseguir los cabezales de impresion. No he podido conseguir informacion en este entido.
