if the printing program is still running, high heat preservation is executed, and if the printing program is not running, low heat preservation is executed.
6. The method of claim 5, wherein the second temperature is lower than the first temperature, and wherein the performing high thermal insulation on the printhead from the first temperature comprises:
calculating a first temperature difference between the second temperature and the first temperature, and taking a temperature interval between the first temperature and the second temperature as a first temperature interval;
dividing the first temperature interval into a plurality of first sub-temperature intervals according to the first temperature difference and a preset first temperature interval;
dividing the total electric energy for high heat preservation into a plurality of parts of first sub-electric energy according to the number of the first sub-temperature intervals, wherein the fraction of the first sub-electric energy is consistent with the number of the first sub-temperature intervals;
every time the temperature slides to a first subinterval, a first piece of sub-electric energy is called for heat preservation.
7. The method of claim 6, wherein performing low thermal insulation on the printhead comprises:
calculating a second temperature difference between the second temperature and the room temperature, and taking a temperature interval between the second temperature and the room temperature as a second temperature interval;
dividing the second temperature interval into a plurality of second sub-temperature intervals according to the second temperature difference and a preset second temperature interval;
dividing the total electric energy for low heat preservation into a plurality of second sub-electric energy according to the number of the second sub-temperature intervals, wherein the fraction of the second sub-electric energy is consistent with the number of the second sub-temperature intervals;
every time the temperature slides to a second subinterval, a second piece of sub-electric energy is called for heat preservation.
8. A heating control device of a thermal printer, the device comprising:
the acquisition module is used for acquiring the print task and determining the data volume of the print task;
the heating module is used for heating the printing head and selecting an initial printing temperature from a first working temperature and a second working temperature according to the data volume of the printing task, wherein the first working temperature is smaller than the second working temperature;
the printing module is used for completing printing and naturally cooling the printing head;
the first judging module is used for judging whether to execute heat preservation according to the connection condition when the temperature of the printing head is reduced to the set first temperature;
the cooling module is used for enabling the printing head to continue to naturally cool if the heat preservation is not executed;
the second judging module is used for judging whether to execute high heat preservation or low heat preservation according to the program state if the heat preservation is executed;
the high heat preservation module is used for carrying out high heat preservation on the printing head from the first temperature if the high heat preservation is carried out;
and the low heat preservation module is used for carrying out low heat preservation on the printing head when the printing head is naturally cooled to the second temperature if the low heat preservation is carried out.
9. A heating control system for a thermal printer, the system comprising:
a thermal printer for thermal printing;
computer device in communication with a thermal printer for performing the method of controlling heating of a thermal printer according to any one of claims 1 to 7.
