No, you generally do not need to print a physical paper ticket for Deutsche Bahn (DB) trains in 2026. DB has moved aggressively toward a "Green Transformation," promoting digital tickets as the environmentally friendly standard. When you book via the DB Navigator app or the official website, you receive a digital ticket with a QR code that can be scanned directly from your smartphone or tablet by the conductor. Even if you receive your ticket as a PDF via email, showing the PDF on your device is sufficient for inspection. Paper tickets are now largely reserved for those who purchase them directly from a station vending machine or travel center. For long-distance journeys (ICE/IC), you can even book a digital ticket up to 10 minutes after the train has departed, provided there is at least 10 minutes of travel time to the next stop. Having a backup screenshot of your QR code is recommended in case of poor internet connectivity.
