Flutter票据打印插件sunmi_print_ticket的使用

重要事项

此插件仅支持Android平台！

✅ 跳行（n）行
✅ 开启/关闭加粗模式
✅ 调整字体大小
✅ 可以打印二维码
✅ 可以打印表格
✅ 使用SignikaNegative-Bold字体作为大字体
✅ 使用OpenSans-Bold字体作为大字体
✅ 将字体大小设置为20作为中心字体大小，以区分两种字体
✅ 切纸 - 专用方法用于切割行

测试设备

Sunmi V2 Pro

导入包

import 'package:easy_ticket_b08/features/printer_pos/service_printer_pos/sunmi_printer.dart';
// 所有sunmi打印机的方法都需要异步等待

await SunmiPrinter.bindPrinterService(); // 初始化打印机
await SunmiPrinter.startPrinter(); // 启动打印机
await SunmiPrinter.printLine(3); // 跳过（3）行
await SunmiPrinter.cutPaper(); // 切纸
await SunmiPrinter.unbindPrinterService(); // 解绑打印机

示例：打印停车票

await SunmiPrinter.startPrinter();
await SunmiPrinter.printText(text: AppConst.nameCompany, bold: true, size: 20);
await SunmiPrinter.printText(text: "${AppConst.taxCodeName} ${AppConst.taxCodeCustomer}", bold: false, size: 20); // size =20 : 打印机字体大小
await SunmiPrinter.setAlignment(1); // 0 : 左对齐, 1 : 居中对齐, 2 : 右对齐
await SunmiPrinter.printLine(3); // 跳过（3）行
await SunmiPrinter.cutPaper(); // 专用方法用于切割行

示例：打印发票表格

await SunmiPrinter.printTable(size: 21, cols: [
    ColumnMaker(text: '名称', width: 10, align: 0), // width: 10 : 列宽, 0 - 左对齐, 1 - 居中对齐, 2 - 右对齐
    ColumnMaker(text: '数量', width: 6, align: 1),
    ColumnMaker(text: '单位', width: 10, align: 2),
    ColumnMaker(text: '总价', width: 10, align: 2),
]);
await SunmiPrinter.printTable(cols: [
    ColumnMaker(text: '产品A', width: 10, align: 0),
    ColumnMaker(text: '4x', width: 6, align: 1),
    ColumnMaker(text: '30.00000', width: 10, align: 2),
    ColumnMaker(text: '120.00000', width: 10, align: 2),
]);

class ColumnMaker {
    String text;
    int width;
    int align;
    ColumnMaker({
        this.text = '',
        this.width = 2,
        this.align = 0,
    });
}

示例：打印二维码

await SunmiPrinter.setAlignment(1); // 将二维码调整到居中位置
await SunmiPrinter.printQr(
    dataQRCode:"https://github.com/hueht21",
    modulesize: 5,
    errorlevel: 2);

更多关于Flutter票据打印插件sunmi_print_ticket的使用的实战系列教程也可以访问 https://www.itying.com/category-92-b0.html

当然，以下是如何在Flutter项目中使用sunmi_print_ticket插件进行票据打印的示例代码。这个插件通常用于Sunmi设备（如Sunmi V1、V2等）的票据打印功能。请确保你已经在pubspec.yaml文件中添加了该插件的依赖，并且已经正确配置了你的开发环境。

首先，确保你的pubspec.yaml中包含以下依赖：

dependencies:
  flutter:
    sdk: flutter
  sunmi_print_ticket: ^最新版本号  # 请替换为实际的最新版本号

然后运行flutter pub get来安装依赖。

接下来，你可以在你的Flutter项目中按照以下步骤使用sunmi_print_ticket插件进行票据打印。

1. 导入插件

在你的Dart文件中导入插件：

import 'package:sunmi_print_ticket/sunmi_print_ticket.dart';

2. 初始化插件并打印票据

以下是一个简单的示例，展示如何初始化插件并打印一张票据：

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Sunmi Print Ticket Example'),
        ),
        body: Center(
          child: ElevatedButton(
            onPressed: _printTicket,
            child: Text('Print Ticket'),
          ),
        ),
      ),
    );
  }

  Future<void> _printTicket() async {
    // 初始化插件
    final SunmiPrintTicket printTicket = SunmiPrintTicket();

    // 配置票据内容
    final List<Map<String, dynamic>> ticketData = [
      {
        'type': 'text',
        'data': {
          'text': '店铺名称',
          'fontSize': 24,
          'align': 'center',
          'margin': {'top': 10, 'bottom': 10},

          'margin': {'bottom': 5},
        },
      },
      {
        'type': 'text',
        'data': {
          'text': '香蕉\t\t\t￥3.00\t\t3\t\t￥9.00',
          'fontSize': 18,
          'align': 'left',
          'margin': {'bottom': 10},

注意事项

设备兼容性：确保你的设备是Sunmi支持的设备，并且已经正确连接。
权限配置：确保你的应用已经配置了必要的权限，如蓝牙权限（如果使用的是蓝牙打印）。
数据格式：根据实际需求调整票据数据的内容和格式。

这个示例展示了如何使用sunmi_print_ticket插件进行基本的票据打印。根据你的实际需求，你可能需要调整票据的内容和格式。希望这能帮助你在Flutter项目中实现票据打印功能。
