How to access Default printer or client PC from web application

1. include this javascript in header section of aspx page
 <script language="vbscript" src="Defaultprinter.vbs"  type="text/vbscript"></script>
 <script language="javascript" type="text/javascript">
function printercall()
{
    document.getElementById("<%=Put some ID here%>").value=Printertest();
}
</script>

2.We need to create a vbscript(Defaultprinter.vbs) that will access client pc default printer and call its method from javascript as mention above.In the same way you can access client PC drive as well.

Function Printertest()
Dim strKey, wshShell,printerreturn
' Create WScript Shell object to read the registry
Set wshShell = CreateObject( "WScript.Shell" )
' Read the current default printer from registry
strKey = "HKEY_CURRENT_USER\Software\Microsoft" _
       & "\Windows NT\CurrentVersion\Windows\Device"
   
    'msgbox(strKey)
printerreturn=Trim( Split( wshShell.RegRead( strKey ), "," )(0) )
msgbox (printerreturn)
' Release the Shell object
Set wshShell = Nothing
Printertest=printerreturn
End Function

3. call javascript usually as we call on button click or page load or as per ur wish.

btnPrint.Attributes.Add("OnClick", "printercall()");

Hope this help you.
