Help with Thermal Label Fixer

Install and use

1. Install Thermal Label Fixer from the Chrome Web Store.
2. Open the Vinted shipping-label PDF.
3. Click the Thermal Label Fixer extension button.
4. Open the converted 4x6 PDF and print it.

Supported workflow

Vinted is currently the only supported marketplace. The extension works with supported Vinted shipping-label PDFs from the expected signed shipping-label host.

Printing tips

• Use 4x6 label paper.
• Choose Actual Size or 100% in the browser print dialog.
• Do not use Fit to page if it changes the label size.
• Confirm the print preview shows the label filling the 4x6 page.

Troubleshooting

• If the extension says the page is unsupported, open the Vinted label PDF directly and try again.
• If the signed label link has expired, request or open a fresh label from Vinted.
• If the PDF opens but prints too small, check that the print scale is Actual Size or 100%.
• If the label does not fit, confirm the selected paper size is 4x6.
