热变色层被加热擦除。 使用适当的时间和温度设定值，使层无色。 局部进一步加热，使用不同的设定间隔和温度，会导致颜色变化，随后是擦除温度以下的快速冷却，使印刷点完好无损。 重复该过程，直到所有行的点都已被打印。 相应的热敏打印设备包括独立声明。

Method and apparatus for deleting and printing of a carrier (K) a Thermochromic layer (TS), which is moved by heating to a quenching temperature during an erase time in a colorless ground state and by local movement via a color change temperature for a color change time and subsequent rapid cooling is provided under the erasing temperature with a corresponding pressure pattern by an electrically heatable thermal point line (TZ) is the intended pressure pattern selectively heated in accordance with accordingly and cooled and each subsequently moved to a next line of dots until all spent to write pixel rows under the thermal point line (TZ) have been. A simple device for carrying out the method is disclosed.
