}

PosPrintResult res =
await printerManager.printTicket(await test(paper));
}

Future<List> test(PaperSize paper) async {
var profile = await CapabilityProfile.load();
final Generator ticket = Generator(paper, profile);
List bytes = [];
// printerSize = '3';

try {
  bytes += ticket.text(
    'COMAPMY NAME',
    styles: const PosStyles(
        align: PosAlign.center,
        bold: true),
  );
  bytes += ticket.text('');

  bytes += ticket.text('ADDRESS 1 XXXXX',
