I'm a little confused about what you're asking about, but if your problem is how to call a javascript function located in the IFRAME-file, you could do it like this:


1) Try to name your IFRAME

<iframe id=iframeHAWB_LABELS name=iframeHAWB_LABELS  style='width:0;height:0;'></iframe>

and then 2) call then function like this:

self.frames['iframeHAWB_LABELS'].sendPageToPrinter();

The important information is in upper comment, but a bit confusing.
Therefore I do repeat it:
1.) Add the name attribute in your iframe tag.
2.) Access the iframe in your  printPages() function like this:

function printPages()
    {
         obj = self.frames.iframeHAWB_LABELS;
         obj.src = "etrans/air/ETAHouseDocLabelPrint.jsp?houseDocId="+document.house.houseDocId.value;
         obj.focus();
...and so on.

Sorry, I just noticed that your function contains also typos.
Here the revised function:

function printPages()
    {
         obj = self.frames.iframeHAWB_LABELS;
         obj.src = "etrans/air/ETAHouseDocLabelPrint.jsp?houseDocId="+document.house.houseDocId.value;
         obj.focus();
         msg = "Do you want to Print Lables using default printer ";
         if(confirm(msg))
         {
                   obj.sendPageToPrinter();
         }
         else
         {
                      obj.print();
         }
         return false;
    }

Sorry again.
The focus() has to be near the print() call:

       else
        {
                     obj.focus();
                     obj.print();
        }


Also you could experiance timing problems if the page loading with new src into iframe takes longer then the confirm() request.
