The Impresoras EPSON USB Windows driver is essentially the same as the EPSON USB-printer driver I explained earlier. "Impresoras" is the Spanish word for "printers," so the term you're using refers to the same type of software (driver) needed for EPSON printers to work with a Windows computer via a USB connection.
If your computer is set to Spanish or you're working with a Spanish-language version of Windows, the driver will be referred to as the "Impresoras EPSON USB Windows driver." The installation process is identical, regardless of language.
