I was crazy searching for the driver and original software (HP Precision Scan LT)utility for my ScanJet 4100C (with USB). Now I have this original CD and will be pleased if it is useful for you. Actually I was ready to upload driver folder together with software, but total file size would exceed 21mb and this site admin allows only up to 10mb uploads. So, only driver folder is posted. It works without bugs.
