Please use the recommended thermal paper or same quality paper, otherwise it will influence
the printing quality and decrease the thermal printer head life;
Don’t stick the paper on the roll paper mandril;
If the thermal paper is polluted by chemical or oil, the thermal paper heat sensibility decreases,
which will influence the printing quality;
Don’t use finger nail or hard articles to touch the surface of thermal paper, otherwise it will
cause color fading;
When the environment temperature is higher than 70°C, the thermal paper color will fade, so
pay attention to the influence of temperature, humidity and sunlight.
