To find your EPSON printer driver, visit the official EPSON website (www.epson.com or your regional EPSON site). Navigate to the "Support" or "Downloads" section, then enter your printer model number. Select your operating system (Windows, macOS, etc.), and download the latest driver version available. Follow the on-screen instructions to install it. Alternatively, you can use the included installation CD if available, though downloading the latest version is recommended.
