Package Flutter Bluetooth to Zebra

问题

I need to add printing functionality on a zebra ZQ520 bluetooth thermal printer in an application developed in flutter (Android), does anyone have any suggestions or packages to perform this task? I tried with the packages: esc_pos_printer, esc_pos_bluetooth, flutter-zsdk, zsdk , but I was not successful.

Thank you!

You can have mine plugin from https://github.com/gmeles/flutter_cblue

You place it in the project root folder and add your dependency on pub spec.yaml like

dependencies:

  flutter:
    sdk: flutter
................
  flutter_cblue:
    path: ../flutter_cblue

The printer must be already paired and it's name must starts with 'zebra'

After that you only send strings

import 'package:flutter_cblue/flutter_cblue.dart';

FlutterCblue.printToBT(printStr: '^XA^CFA,30 ^FO50,300^FDHello World^FS ^XZ')
                                  .then((result) {


.............

1. It works only on android, have no need for iOS for this project

2. Check the code ......

3. Check that your ZPL commands are correct using http://labelary.com/viewer.html
