Worth reading this Brother study on thermal paper degradation: https://www.anixter.com/content/dam/Suppliers/Brother/White%20Papers/ThermalPaperWhitePaper%20(WP1).pdf https://www.anixter.com/content/dam/Suppliers/Brother/White%... Worth looking at Figure 3 showing how different samples of thermal paper have vastly difference reactions to high temperatures. Once had a set of Aliexpress plastic water carriers take 6 months to arrive to me during COVID and it when it arrived, it seemed like the plasticizers from the carriers (or the factory?) severely degraded the thermal shipping label.
