I have a scanner (HP Scanjet 4400c), which is plugged in and everything, but that does not appear in the control panel, scanners and cameras and then later, when I run the program "HPprecisionscan" that I downloaded from hp, AC told me that the scanner is not found.What should I do? I am using windows 7 and HP Scanjet 4400c drivers is still missing from my system, i can not find them. Please help.
