Method and apparatus for implementing thermal printing

A method for implementing thermal printing, comprising:

• step S1:
• obtaining power information of an electronic device upon receiving a printing instruction, obtaining a maximum available power based on the power information of the electronic device, and calculating a number of printable dots based on the maximum available power and power consumption of single-dot printing;
• step S2:
• parsing the printing instruction to obtain data to be printed, converting the data to be printed into a two-dimensional dot-matrix pattern, and taking information of a first row in the two-dimensional dot-matrix pattern as current information to be printed;
• step S3:
• obtaining a number of ink dots from the current information to be printed, and determining whether the number of ink dots is greater than the number of printable dots;
• if so, executing step S5;
• otherwise, executing step S4;
• step S4:
• energizing a heating element at a corresponding position on a print head for a preset duration based on an ink-dot position in the current information to be printed, and controlling a motor to feed paper, and executing step S6;
• step S5:
• segmenting the current information to be printed based on the number of printable dots, keeping ink-dot positions in information of each segment unchanged, and filling other positions with zeroes to obtain virtual row information with a same length as the current information to be printed;
• energizing heating elements at corresponding positions on the print head for the preset duration based on the ink-dot positions in each piece of virtual row information sequentially, controlling the motor to feed paper, and executing step S6;
• and
• step S6:
• determining whether the two-dimensional dot-matrix pattern has been printed completely;
• if so, ending;
• otherwise, taking information of a next row in the two-dimensional dot-matrix pattern as the current information to be printed and returning to the step S3.
