The Hewlett-Packard ScanJet 4200C is a flatbed scanner produced by HP. It connects to your computer via USB (or sometimes parallel port, depending on the model) and is used to scan documents and images. To use the scanner on a Windows system, you need the appropriate Windows driver to ensure the computer and the scanner communicate properly.

The HP ScanJet 4200C Windows driver is software that allows your Windows computer to recognize and use the scanner. Without the correct driver, your system may not detect the scanner, or it may not function properly when trying to scan documents.
