The following is a page definition in a print template:

<IE:DEVICERECT ID="page2" CLASS="masterstyle" MEDIA="print">
  <IE:LAYOUTRECT ID="layoutrect2" CLASS="contentstyle"
  ONLAYOUTCOMPLETE="setTimeout('CheckIfPrintRequested()', 100)"/>
</IE:DEVICERECT>
The page's LAYOUTRECT element has an event handler attached to it:

ONLAYOUTCOMPLETE="setTimeout('CheckIfPrintRequested()', 100)"
We want to call the function CheckIfPrintRequested() 100 milliseconds after the page is laid out. This is to ensure that the page won't be sent to the printer before the page's layout is complete and the event is consumed. A one millisecond interval would have been sufficient, but we want to play it safe.
