Tested Devices

import packages

import 'package:easy_ticket_b08/features/printer_pos/service_printer_pos/sunmi_printer.dart'; // all method from sunmi printer need to async await

await SunmiPrinter.bindPrinterService(); // Initialize the printer await SunmiPrinter.startPrinter(); // start printer await SunmiPrinter.printLine(3); // Jump (3) lines await SunmiPrinter.cutPaper(); // await SunmiPrinter.unbindPrinterService(); // unbind printer

## Example of printing a parking ticket
   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 : font size printer
   await SunmiPrinter.setAlignment(1); // 0 : Left align , 1 : Center align, 2 : Right align
   await SunmiPrinter.printLine(3); // Jump (3) lines
   await SunmiPrinter.cutPaper(); // Dedicated method just to cut the line

## Example of printing invoice table
   await SunmiPrinter.printTable(size: 21, cols: [
       ColumnMaker(text: 'Name', width: 10, align: 0), // width: 10 Width of column , 0 - LEFT, 1 - CENTER, 2 - RIGHT  
       ColumnMaker(text: 'Qty', width: 6, align: 1),
       ColumnMaker(text: 'UN', width: 10, align: 2),
       ColumnMaker(text: 'TOT', width: 10, align: 2),
   ]);
   await SunmiPrinter.printTable(cols: [
       ColumnMaker(text: 'Sản phẩm 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,
       });
       }
   }
## Example of printing qrcode
   await SunmiPrinter.setAlignment(1); // Adjust the qrcode in the center position
   await SunmiPrinter.printQr(
       dataQRCode:"https://github.com/hueht21",
       modulesize: 5,
       errorlevel: 2);
