If your Zebra Label Printer keeps reprinting the last label from a previous print job, there is an easy way to take care of that. Navigate to Control Panel – View Devices and Printers (under Hardware and Sound) – right-click on the printer and select Printer Properties, then click on Printer Commands and insert a code: <0D> as shown on screenshot below.
Hit Apply and then hit OK. You are done! On the next reprint, it will still have leftover label from the previous queue, however, the next print job after that will be correct without any extra labels.
