how print euro symbol with flutter and zebra printer?-CodePudding

i have my flutter app that use cpcl commands to communicate with zebra zq220 printer. it works fine but doesn't print € euro symbol

here my function to create cpcl commands



List<String>lst=[];
lst.add("TEXT 4 2 0 80 € 12.9");
//HERE WITH OTHER COMMANDS AND FINALLY
String ss="";
for(int i=0;i<lst.length;  i)
{
ss ="${lst[i]}\r\n"
}
await sendByte(ss);

and here my function to send to my zebra printer

Future<void> sendByte(String scmd) async {
  
    List<BluetoothService> services = await connectDevice!.discoverServices();
    for (BluetoothService service in services) {
     
      var characteristics = service.characteristics;
     
      for (BluetoothCharacteristic c in characteristics) {
        
//here are three encode type that work fine all with zebra printer, but they don't print euro symbol
           c.write(gbk.encode(scmd));
           //c.write(utf8.encode(scmd));
          //c.write(gbk_bytes.encode(scmd));
       
      }
    }
  }

So could someone help me to find the solution, how to print euro symbol with this?? Thanks in advance Best Regards

Try getting the euro symbol by entering the escape character sequence into the string instead of the euro symbol.

The euro escape characters are highlighted in red below:

If i remember well, and if you use ZPL for communication with printer, you can send the $ char to printer. Printer will print the good char if correctly parametered.

In my case it was a zebra label printer.
