Printing principle of label printer

The basic printing principle of the label printer can be divided into two printing methods, thermal printing and thermal transfer printing. Thermal printing and thermal transfer printing are good label printing methods. At this time, because these two printing methods can be easily applied to various adhesive label materials, and can print high and high-quality patterns, they also have very good edge definition. Each technology can generate one-dimensional and two-dimensional bar code symbols, with the same printing clarity and speed as the text font.

In the two printing methods of reheat transfer and thermal printing, the barcode print head is used for heating. Thermal transfer barcode printing is a durable pattern printed on the material by heating the carbon belt. Thermal printing does not need to use carbon tape, but directly prints characters and graphics on label paper. In thermal transfer printing, the bar code print head heats the ribbon, and then the ink will melt on the label paper and then form a pattern. The ribbon material will be absorbed by the medium, and the pattern will become a part of the label. This technology provides better durability and pattern quality. Thermal printing uses a chemically treated thermal medium. When the medium passes through the thermal head, the medium will turn black. Thermal printers do not require ink, toner, or ribbon. The simple design makes the thermal printer easy to use and durable. Because no ribbon is required, the pattern on the heat medium will fade over time. If the label is exposed to heat, light or other catalysts, the material will darken and the barcode will not be read.
