Looks nice, but took me 2 hours with HP tech service to find out that it didn't like my USB 2.0 connector on the motherboard. Apparently this is a common problem and they sent me a usb 2.0 hub to use.Now that it's "working". It's unpredictable. Sometimes I'll scan multiple images without a hitch. Other days, I'm happy if I can scan 1-2 pages before crashing and having to reboot to continue scanning.I expected better from HP. When are software and hardware manufacturers going to learn that end users want to use their products and not spend hours to set them up.
