The gp3150 tag machine prints an empty one
This is the problem of setting the label or printing the sensor without alignment.Generally the label size settings.
If this doesn't work out, the printer sensor doesn't work properly and doesn't properly check the label paper size. You can adjust the location of the sensor automatically or manually through the button on the printer, or restart the printer after the factory settings have been restored
Set size in label printing software, open the printer first, find the volume name in the "page", is used to adjust the size of the label paper, find the dimensions with their actual printing labels, if not, a new.
