Description

Label editing and printing method and system based on physical resolution of printer Technical Field The invention relates to a label editing and printing system based on printer physical resolution. Background The label is used as an important carrier for industrial production, logistics management and product tracing, is widely applied to the fields of manufacturing, storage, medical treatment, retail and the like, and the existing label editing and printing software generally constructs a label template in a screen pixel or assembly mode and performs adaptive output through driving or instructions in a printing stage. However, the printer has a fixed physical resolution in the actual working process, and the printing instructions thereof all show discretization characteristics in terms of position, size, bar code magnification and the like. Because the existing software does not introduce the physical resolution constraint of the printer in the editing stage, the problems of size deviation, position drift and accuracy degradation after multiple exports and imports exist between the display effect of the editing interface and the actual printing result. In addition, along with the improvement of the industrial automation level, the labels are not only used for printing output, but also gradually participate in links such as printing quality detection, visual comparison and production takt control, and the like, the conventional scheme generally lacks systematic support for printing task scheduling, printing image output and collaborative work with a visual detection system, and is difficult to meet the industrial application requirements of high consistency and high reliability.
