NOTE: The following code was printer settings to an USB Zebra ZPL printer called "Zebra TLP2844-Z". You must change it to match your target printer i.e. a Zebra ZPL or EPL printer including the name. In addition, in the code the label size is set to 3in x 2in so please change it based on your needs.
