The HP Scanjet 8300 series is a line of flatbed scanners manufactured by Hewlett-Packard (HP). These scanners are typically used for scanning documents and images, and they can be connected to a computer via USB or network. The HP Scanjet 8300 series Windows driver is the software that enables your computer to communicate with the scanner, allowing you to scan documents and images directly to your PC using compatible scanning software (like HP's Scan software or third-party programs like Adobe Acrobat or Microsoft Office).
