There is a part missing in the middle of this jewelry label. If the whole label is like this, it won't print. Operation 1: Turn off the power, hold down the pause button, and turn on the power immediately, and release the pause button after three seconds. 2. Re-measure the width and height of the label (mainly), and then compare whether the width and height of the typesetting software and the driver are consistent. 3. Change the longitudinal spacing to 3 mm (secondary). Remarks: Focus on the second point.
