The common ones are mostly 80mm x Φ60mm and 57mm x Φ50mm two common specifications.
Thermal paper is generally sold in rolls, generally 80mm x Φ60mm, 57mm x Φ50mm and other specifications are the most common, the number in front of the width of the paper roll, followed by the diameter. The width of the general error of 1, 2mm, if the use of no impact, because the printer generally can not print the edge, but the diameter of the paper roll on the buyer's influence is relatively large.
Because the total length of the roll of paper rolled directly related to the cost-effectiveness of this roll of paper, if the diameter is 60mm, but the actual only 58mm, then the length of a roll of paper will be reduced by about 1 meter (depending on how much to reduce the thickness of the paper), but the thermal paper rolls sold on the market are generally labeled X0, the actual diameter of the actual diameter of the rolls is often less than the X0.
There is also need to pay attention to The diameter of a roll of paper in the middle of a core, some merchants will also be on the core to do tricks, choose a larger core, the length of the paper to shorten a lot. Simple way to buyers can take a small ruler to measure the diameter and the diameter of the box labeled whether the same, the diameter of the core also need to pay attention to, so as to avoid unscrupulous business shortages lead to buyers to suffer losses and be fooled.

Thermal paper use:
Thermal Paper: In fax machines As the text and graphics of the communication carrier, that is, as a fax paper; in the medical, measurement system as a recording material, such as electrocardiogram paper, thermal instrument recording paper, etc.; applied to the Internet terminal printing paper; in commercial activities, used to produce trademarks, sign code (POS), etc., which the fax paper dosage occupies the largest proportion.
Thermal paper production principle is in the ordinary paper base coated with particles of powder, the composition of colorless dyes or other acidic substances, phenol or film separation, in the heat conditions, the film melts, powder mixing color reaction. The color on the thermal paper is not stable, easy to fade, resulting in the content of the document is difficult to identify.
Commonly used lottery tickets are thermal paper.
Ordinary thermal paper is not suitable for long-term preservation, but good thermal paper has been able to save 30 years or even longer.
