The EPSON Mass Storage Device driver is typically used for Epson printers or scanners that include storage capabilities (such as USB flash drives, memory cards, or similar features), or for Epson multifunction devices that allow the connection of external storage devices to the printer or scanner for direct printing or scanning. This driver allows your Windows computer to interact with the Epson device and its storage functions correctly, enabling you to transfer files between the device and your computer.
