Control method of miniature thermal printer

The invention discloses a control method of a miniature thermal printer, and belongs to the technical field of thermal printing. The control method comprises the following steps of S1, calculating therotating speed of a motor according to requirements for parameters of a motor, parameters of a thermal head, mechanical design of the printer and printing speed: controlling a micro-step drive of 2-2phases of the thermal printer motor, determining a reasonable number of segments through calculation according to specifications of the thermal printing head, determining the angle of a micro-step ofthe motor, and calculating the rotating speed of the motor at idle time; and S2, calculating a count value and a comparison value of a timer according to the requirement for the motor rotating speedcalculated in the step S1: determining the count value of the timer according to the motor rotating speed, and determining the comparison value according to the position of the motor.
