flutter_xprinter_tspl_sdk

Windows Flutter plugin for XPrinter TSPL / TSPL2 label printers.

This package keeps label printing separate from flutter_xprinter_sdk, which continues to focus on ESC/POS receipt printers.

Platform support

Transports

await TsplConnection.connect(
  type: XprinterTsplConnectionType.usb,
  address: '', // first USB printer, maps to "USB,"
);

await TsplConnection.connect(
  type: XprinterTsplConnectionType.tcp,
  address: '192.168.1.20', // maps to "NET,192.168.1.20"
);

await TsplConnection.connect(
  type: XprinterTsplConnectionType.serial,
  address: 'COM1,9600',
);

Print a label

await TsplConnection.connect(
  type: XprinterTsplConnectionType.tcp,
  address: '192.168.1.20',
);

await TsplPrinter.setup(
  labelWidthMm: 58,
  labelHeightMm: 40,
  gapHeightMm: 2,
);
await TsplPrinter.clearBuffer();
await TsplPrinter.text(x: 30, y: 30, text: 'BILLZ TSPL');
await TsplPrinter.barcode(x: 30, y: 80, content: '1234567890');
await TsplPrinter.qrCode(x: 330, y: 40, content: 'https://billz.ai');
await TsplPrinter.print();

await TsplConnection.disconnect();

Raw commands

The Dart layer builds standard TSPL command bytes and the Windows native layer only opens the vendor SDK port and writes bytes. For commands not wrapped yet:

await TsplPrinter.sendCommands([
  'SIZE 58 mm,40 mm',
  'GAP 2 mm,0 mm',
  'CLS',
  'TEXT 30,30,"3",0,1,1,"Raw TSPL"',
  'PRINT 1,1',
]);
