Issue : ERROR_PRINTER_SETTING_NOT_SUPPORTED

[anchals333]

Hi, I'm using another_brother: ^0.0.34. My printer is QL-820NWB. I'm getting an error that printer settings not supported. Can you let me know what I'm doing wrong. Here is my code :

void printVisitor() async {
    try {
      var printer = Printer();
      var printInfo = PrinterInfo();
      printInfo.printerModel = Model.QL_820NWB;
      printInfo.printMode = PrintMode.ORIGINAL;
      printInfo.isAutoCut = true;
      printInfo.port = Port.NET;
      printInfo.paperSize = PaperSize.CUSTOM;
      printInfo.customPaperWidth = 60;
       printInfo.customPaperLength = 100;
      // printInfo.binCustomPaper = BinPaper_RJ2050.RD_W58mm;
      printInfo.customPaperInfo = CustomPaperInfo.newCustomDiaCutPaper(Model.QL_820NWB, Unit.Mm,
          60, 90, 0, 0, 0, 0, 0);
      // printInfo.pap
      // Set the label type.
      printInfo.labelNameIndex = 15;
      // Set the printer info so we can use the SDK to get the printers.
      await printer.setPrinterInfo(printInfo);
      // Get a list of printers with my model available in the network.
      List<NetPrinter> printers = await printer.getNetPrinters([Model.QL_820NWB.getName()]);
      if (printers.isEmpty) {
        // Show a message if no printers are found.
        ScaffoldMessenger.of(context).showSnackBar(const SnackBar(
          content: Padding(
            padding: EdgeInsets.all(8.0),
            child: Text("No printers found on your network."),
          ),
        ));
       return;
      }
      // Get the IP Address from the first printer found.
      printInfo.ipAddress = printers.first.ipAddress;
      Utils.printLog(message: "Printer found : ${printers.first.ipAddress}");
      printer.setPrinterInfo(printInfo);
      PrinterStatus status = await printer.printImage(await loadImage());
      Utils.printLog(message: "Printer status : ${status.toMap()}");
      Utils.printLog(message: "Printer info : ${printInfo.toMap()}");
    } catch (e) {
      Utils.printLog(message: "Printer Error : ${e.toString()}");
    }
  }

My printer result :

This has been resolved, it was the issue of size of image.
