As we can see,Thermal paper is essentially cylinder.And we usually describe it by “Width x Diameter x Core”.Take an example:
- 80mm x 80mm x 12mm means : The paper width is 80mm,paper diameter is 80mm,while the core is 12mm.
- 57mm x 50mm x 12mm means : The paper width is 57mm,the diameter is 50mm,the core is 12mm.
The normal paper roll sizes are: 80x80x12mm,57x50x12mm,80x70x12mm,whatever. Any sizes are available for us to make.
