Answer 1

Any device connected to a network will communicate via their IP and Ports / sockets. The simplest way to connect via telnet or socket and write the data to their socket buffers.

try 
    {
    Socket sock = new Socket("192.168.1.222", 9100);
    PrintWriter oStream = new PrintWriter(sock.getOutputStream());
        oStream.println("HI,test from Android Device");
        oStream.println("\n\n\n");
        oStream.close();
        sock.close(); 
    }
    catch (UnknownHostException e) 
    {
        e.printStackTrace();
    } 
    catch (IOException e) 
    { 
        e.printStackTrace();
    }
