The XTL 300 prints through DYMO’s free DYMO ID app on a Windows computer, connected by USB.

1. Tap CSV for DYMO ID and get the file onto your PC (email, OneDrive, or open TKQrGen on the PC and make it there).
2. In DYMO ID, pick the XTL 300, the same tape width, and the General label type.
3. Add a Text box and a Barcode. Set the barcode type to QR Code (or Code 128 if you chose a barcode here).
4. Use Import data and choose the CSV file.
5. Drag the Label Text column onto the text box, and Code Value onto the barcode.
6. Print, or save it and send it to the XTL 300 to print later.

DYMO ID draws the code at the printer’s full sharpness. For a single label you can also tap Save label as an image and insert it in DYMO ID with Insert, Image.
