Why does the red light always jumps when the barcode printer prints?


In this case, there are several reasons for this:

First, the label size in the barcode software does not match the actual label size.

Second, the printing method inside the bar code machine is set incorrectly. The use of the ribbon is required to be set to the thermal transfer mode. When the ribbon is not used, it needs to be set to the thermal mode.

Third, the positioning method of the label media inside the barcode driver needs to be set correctly. For example, the print interval label needs to use a transmissive sensor, such as a label with a black label, and needs to be set as a reflective sensor.

Fourth, check that the label ribbon is installed correctly.

Fifth, you can recalibrate the sensor.
