remarkably reduce the life of the thermal head.
Store the paper in a dry, cool and dark place.
When pasting printed pages, use water-based glue. (starch glue, synthetic glue, etc.)
The surface of thermal paper has been specially treated with a chemical agent to
produce coloring by thermal chemical reaction.
