Summary: My only complaint would be that the replacement toner is so expensive. I use the B/W option to save on toner when I don't need color prints. The cartridges do last a long time, however. I bought this machine in Jan of 2009, and have had zero problems. I don't think it is very loud.
Summary: Bought this out of my school classrooom budget. Began throwing all kinds of error messages right out of the box. HP dragged their feet long enough that it went out of warranty...Now I turn it on just for the sole purpose of watching all the front panel lights flash! That's about all its good for.
Summary: I have been a big fan of HP printers from the get go. They have a reputation of building high quality, easily maintainable, and low total cost of ownership laser printers. I have serviced HP, Lexmark printers for over 15 years as well as a few Xerox, Brother and Canon printers as well.
Summary: I bought this printer one year ago for roughly 700 Euro. Within two months the paper started to come out crumpled. I phoned the company where I bought it. Unable to fix it. Gave the case over to HP.
