2.2.2 Notices
Notes：
Please use the recommended thermal paper or same quality paper,
otherwise it will influence the printing quality and decrease the thermal
print head life
Don’t stick the paper on the paper roll 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
