Deprecated Methods (@Deprecated)

The following methods have been kept for compatibility reasons but will be removed in future releases. Avoid using them in new implementations:

  • SunmiPrinter.initPrinter()
  • SunmiPrinter.bold()
  • SunmiPrinter.resetBold()
  • SunmiPrinter.printRawData(Uint8List data) → Use printEscPos() instead
  • SunmiPrinter.setCustomFontSize(int size)
  • SunmiPrinter.setAlignment(dynamic align)
  • SunmiPrinter.resetFontSize()
  • SunmiPrinter.setFontSize(dynamic size)
  • SunmiPrinter.startTransactionPrint(bool trans)
  • SunmiPrinter.exitTransactionPrint(bool trans)
  • SunmiPrinter.bindingPrinter()
  • SunmiPrinter.cut() → Use cutPaper() instead

You can also combine this package with the package esc_pos_utils

With this package you can create a custom escpos and than you don't need to use any other command. This is good if you already have a code that another printers use, and u can reuse this code as well

// import packages
import 'package:sunmi_printer_plus/sunmi_printer_plus.dart';

Example code when use SunmiPrinter

        await SunmiPrinter.printText('Simple raw text');
        await SunmiPrinter.printText('Bold text centered',
            style: SunmiTextStyle(
            bold: true,
            align: SunmiPrintAlign.CENTER,
            ));

        await SunmiPrinter.lineWrap(2); // Jump 2 lines
        await SunmiPrinter.printText('Very Large font!',
            style: SunmiTextStyle(
            fontSize: 80,
            ));
                          
        await SunmiPrinter.printText('Custom font size!!!',
            style: SunmiTextStyle(
            fontSize: 32,
            ));
                          
        await SunmiPrinter.printQRCode(
            'https://github.com/brasizza/sunmi_printer',
            style: SunmiQrcodeStyle(
            qrcodeSize: 3,
            errorLevel: SunmiQrcodeLevel.LEVEL_H,
            )); // PRINT A QRCODE

Example code for LCD functions

await SunmiLcd.configLCD(SunmiLCDStatus)
 await SunmiLcd.lcdString('Hello'); //Write a simple line 
 await SunmiLcd.lcdString('Hello' , 12 , true); //Write a simple line with 12 in size and fill screen

 Uint8List byte = await readFileBytes('assets/images/128x40.png');
 await SunmiLcd.lcdImage(byte); // Put an image in LCD

Example to open the cashier

  bool await SunmiDrawer.i.isDrawerOpen(); //check if the cash drawer is connect or disconnect

  await SunmiDrawer.i.openDrawer(); //open de cash drawer
