Problems solved by technology

When the photoelectric sensor is far away from the thermal head, the detected edge of the label will deviate from the position of the print head
However, there is a carbon ribbon sandwiched between the thermal head and the label, and the carbon ribbon has a strong light-absorbing ability, resulting in a very weak signal change. Therefore, the photoelectric sensor cannot be placed close to the thermal head.

Description

[0001] (This application is a divisional case for 201910431138.X, a method for determining the edge of printing equipment, devices and printing media) technical field [0002] The invention relates to the technical field of printing, in particular to a printing device and a method for determining the edge of a printing medium. Background technique [0003] At present, the label printing equipment in the market uses the method of photoelectric sensor detection to locate the edge of the label. Specifically, there is a preset fixed distance between the detection point of the photoelectric sensor and the printing point of the thermal head. During the moving process, after the photoelectric sensor first detects the edge of the label, the motor rotates a fixed number of steps to drive the label belt forward for a fixed distance. At this time, it is determined that the label to be printed is located at the preset position, and then The thermal head executes the printing action on t...
