very easy installation, and excellent print quality. rather slower than I expected for first print out. print was offset by 3mm from page centre - doesn't sound much, but when you have a border round the edge, it's very noticeable. Am awaiting a response from Samsung. I'm also getting an error message telling me that the paper in the tray is 'mismatched', and I have to pull out the tray and re-insert it - annoying.
