PURPOSE:To make it possible to know simply the concn. of a recording pattern at a high or low temp. environment by means of a thermal printer by simulating the concn. of the recording pattern at the high or low temp. environment while the environment at ordinary temp. is kept as it is. CONSTITUTION:The concn. of a pattern of a word or an image which is recorded on a paper by means of a thermal head at an environment of a temp. THL which is higher or lower than an ordinary temp. TM is estimated. When the temp. of the thermal head recording at an ordinary temp. environment is TK and an electric voltage applied for recording at the environment is V, an electric voltage obtd. by calculation based on an equation of V'={(THL+TK-2 TM)/(TK-TM)}1/2.V is applied to the thermal head at an ordinary temp. environment to record a pattern on a paper and the concn. of the pattern which the thermal printer may records on paper at the temp. THL is estimated. |
