await Printing.listPrinters().then((value) async {
  print("**** Printing Printers");
  value.forEach((element) {
    print('Printer: ${element.name}');
    print('Model: ${element.model}');
    printers.add(element.name);
    printers.add(element.model!);
    description.text = '${element.name} : ${element.model} \n';
  });
  if(value.isNotEmpty){
    var result = await Printing.directPrintPdf(
        printer: value[0],
        onLayout: (PdfPageFormat format) async => doc.save()
    );
    print("result : $result");
