Summary: The scanner might be fine for Windows users, but there is no driver for Apple OS X. This includes Snow Leopard, Lion and Mountain Lion. The HP drivers only worked with the old Power PC operating system, and since the scanner was discontinued in 2005, HP has no plans to release an updated driver. Even third-party drives depend on the HP kernel, so there aren't any.
Summary: Just a warning to those with Macintosh systems. HP refuses to update their driver for this scanner to work under MacOS Lion, so this hardware becomes trash if you upgrade to the latest MacOS, or even buy a new Mac computer. HP seems to be dropping the ball on a lot things like this these days, which is too bad because they used to make some good stuff. I really like my 4670 scanner but it's now a doorstop!
Summary: I thought the scanner looked great, but I never got it. Must have been lost in the mail somewhere. The seller was not very helpful and slow to answer, and then would not answer when asked for a refund over a month after the purchase and I had still not received it. was to be shipped priority mail, was shipped parcel post with no insurance or any way of tracking to see where it went.
Summary: I'm now on my third scanner of this type. The first worked for ca. 1 week until it went dead in the middle of a scan. I returned it to the shop and soon recieved a new one. This lasted for a month - and the same thing happened again. Well, today I recieved my third scanner, which worked fine - for 15 minutes!! Three different scanners, same problem. The design and consept is great - but that does not help at all. If i could rate this with 0 stars I would.
