GC420t not printing Continuously


I've GC420t label printer, installed and configured on windows 10, printing with perfect alignment single print, but not printing Continuously in case of multiple copies print order...

its stopping after each print, and green button start blinking red color.. I've to open the printer cover and close it again then it'll become green again. then i press the button to print anther one, and then the same for each copy under the same order..
