The print template loader from Microsoft sometimes calls the print template more than once. Since you don't need duplicates of your printout, you need to use an action. For example, the variable invocations is initialized to zero in the beginning, and then is returned immediately upon entry when invocations are greater than one: 
invocations = 0;
function CheckIfPrintRequested() {
  invocations++;
  if (invocations > 1) return;
  switch (dialogArguments.__IE_PrintType) {
    case "Prompt":
      if (printer.showPrintDialog()) PrintPrep();
      break;
    case "NoPrompt":
      PrintPrep();
      break;
    case "Preview":
    default:
      break;
  }
}
