I know I installed it correctly from the CD. I don't know if I should install updates bec my Macbook OS is 10.6.4.
It's getting frustrating because there are documents/photos that I need to scan. When I run the HP Scan software, turn the scanner on and put a picture and press SCAN on the dialogue box, it just says PREPARING TO SCAN and it goes on and on and on and never shows my image/document.
I already tried uninstalling and re-installing the software but still get the same result. Why is it always saying PREPARING TO SCAN and does not communicate with my device? Please help me
Thank you!
