It may be that the operator did not set the electronic scale itself to print, resulting in no label paper when pressing the print button when weighing the goods. This reason only needs to be set by someone familiar with the bar code scale.

It is also possible that the electronic scale was not placed correctly when the label paper was loaded. For example, the label paper is tilted and the label paper is placed incorrectly, which will cause the paper to be unable to print. Therefore, in the case of not printing paper, it is necessary to check whether the label paper in the electronic scale printer is placed correctly.
