Connecting Fiscal printer with flutter app

I’m working on a kitchen app in flutter. So I need to connect different types of printers to get the KOT and customer prints.
I’ve already connected

  1. EPSON thermal printers
  2. Starmonics TSP100III
  3. Bluetooth printers
  4. SUNMI printers

But not able to connect FISCAL printers. It gets connected with the flutter app via Bluetooth but doesn’t take a printout
gives the exception: Unimplemented/Unsupported command

Is there any way to connect fiscal printers with flutter app?

    I think the solution is to implement http Request, this is an Example that I finded this for Printer Epson:

    A SOAP message is returned as the response to the HTTP POST method. The SOAP body contains the response document. To permit cross-domain communication, the response contains the HTTP "Access-Control-Allow-Origin: *" header. See Fiscal Printer Intelligent Features Guide for browser cross-domain information.


[Example]
HTTP/1.1 200 OK Access-Control-Allow-Origin: * Content-Type: text/xml; charset=utf-8 Content-Length: xxxx
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<response success="true" code="" status="xxxxx" />
</s:Body> </s:Envelope>
