    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes
    #FullScreen: False

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

    Dim Socket1 As Socket
    Dim Printer1 As TextWriter
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

    Private Button1 As Button
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    
    Activity.LoadLayout("1")
    
    Socket1.Initialize("Socket1")
    Socket1.Connect("192.168.100.202", 9100, 20000)
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub Socket1_Connected (Successful As Boolean)
    If Successful = False Then
        Msgbox("Error", "")
        Return
    End If
    
    Printer1.Initialize(Socket1.OutputStream)

    Msgbox("Connected", "")

It is so easy with Java! Is Java the better Way?

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();
    }

BTW, the Java code you posted is not really valid. You cannot work with network streams on the main thread.
