Print complete document from stagewebview

Question

I have a air application that shows in a stagewebview a facebook app.
In that facebook app you have to fill in a form.
Under the form there is a print button (that won't work)
So I wrote my own print button.
But the problem is that I have to convert the viewport of the stagewebview to a bitmap
and then print the bitmap to pdf or my printer.
But he always just take the part that is shown on my stage.
But I have to print the whole document that is in the stagewebview...
Can anybody help me?
Here is my code to convert to bitmap and the print...
var bitmapData:BitmapData = new BitmapData(iBreedte,iHoogte);
  webView.location;
  webView.drawViewPortToBitmapData(bitmapData);
  var webViewBitmap:Bitmap = new Bitmap(bitmapData);
  var myPrintJob:PrintJob = new PrintJob();
  var options:PrintJobOptions = new PrintJobOptions();
  options.printAsBitmap = true;
  myPrintJob.start();
  var s:Sprite = new Sprite();
  s.height = iHoogte;
  s.width = iBreedte;
  s.addChild(webViewBitmap);
  s.scaleX = .40;
  s.scaleY = .40;
  myPrintJob.addPage(s, null, options);
myPrintJob.send();

PDL -- thank you for your reply.
What you gave me did spawn the print dialog allowing me to select a printer. However, when the document printed, the number of pages in the document was correct but the pages were empty except for the page x of y along the top and the name of the document along the bottom. Have you seen this before and do you know how to correct? Also, how do you suppress the info across the top and bottom of the report from printing?
Thanks
