Problems solved by technology

[0002] When a thermal printer prints files, sometimes the printer restarts due to abnormal reasons, causing the printer to stop running. In this case, the data to be printed will be lost, or half of the printed files will be invalidated, wasting resources.
The traditional technology is to solve the above problems by installing a backup power supply, but the backup power supply is expensive and not suitable for widespread use

Abstract

The invention relates to a printing method and apparatus of a thermal printer. The method comprises steps of acquiring to-be-printed data, backing-up the to-be-printed data to a memory, starting to print and acquiring line numbers corresponding to a current printing position during the printing, backing-up the line number to the memory, acquiring the line number corresponding to the current printing position and the to-be-printed data both backed-up in the memory when the printer gets abnormal and is restarted, and continuing to print the to-be-printed data from the line number corresponding to the current printing position. A problem of loss of the to-be-printed data can be solved; cancellation of files printed a half can be prevented; the use of backup power supply can be unnecessary; cost and resource use can be saved; and the printing method and apparatus of the thermal printer can be widely applied.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a printing method and device of a thermal printer. Background technique [0002] When a thermal printer prints a file, sometimes the printer restarts due to abnormal reasons, causing the printer to stop running. In this case, the data to be printed will be lost, or half of the printed file will be invalidated, wasting resources. The traditional technology solves the above problems by installing a backup power supply. However, the backup power supply is expensive and not suitable for widespread use. Contents of the invention [0003] Based on this, it is necessary to provide a printing method and device for a thermal printer that can save costs in order to address the above problems. [0004] A printing method of a thermal printer, the method comprising: [0005] Acquiring the data to be printed, and backing up the data to be printed into the memory; [0006] Start printing ...
