sendBinaryFile method
Send the binary file containing the command. Since the status check is not performed, it is sent even if the printer specified by printerModel is different from the actually connected printer.
Implementation
Future<PrinterStatus> sendBinaryFile(String filepath) async {
var params = {
"printerId": mPrinterId,
"printInfo": mPrinterInfo.toMap(),
"filePath" : filepath,
};
final Map resultMap = await _channel.invokeMethod("sendBinaryFile", params);
PrinterStatus status = PrinterStatus.fromMap(resultMap);
return status;
}
