Print footer

I am novice Java Programmer. We wrote following code and put it under
C:\Program Files\Adobe\Acrobat 7.0\Acrobat\Javascripts.
I can open pdf and from menu click on “Print with Footer” and it print documents with footer.
But if I do not open and select the pdf file from window explorer and do the right click then it prints without footer. How can I print document with footer without opening and using following code

app.addMenuItem({cName:"Print with Footer", cParent:"File", nPos:20, cExec:"PrtFooter();"});

//Print bookmarked Pages
function PrtFooter()
{
for (var p = 0; p < this.numPages; p++)
{
var fd = this.addField("Date", "text", p, [10,10, 400,28]);
fd.textSize=8; fd.value = "Dt: " + util.printd("yyyy/mm/dd", new Date()) + " (" + this.path +")"

}
app.execMenuItem("Print");
{

for (var p = 0; p < this.numPages; p++)
{

} }
}
