Printing with referenced images

Question

I have a print component in my Flex application which works fine if I embed the header image to be printed.  But if I merely link it as an external file, it appears to load, but somehow the print code creates the page too rapidly and the header does not get included in the print output (though it appears in the component micorseconds after the print dialog closes). 
I tried a workaround to give the image a chance to upload into the print component completely (see below), but it is inconsistent and only works for faster connections.
callPrint is only called when creationComplete of the component, but it does not appear to be the case--the image is not completely created when the print function is called by  creationComplete="callPrint()"
Has anyone else experienced a problem with this, and is there a workaround?
thanks
WORKAROUND ATTEMPT CODE BELOW:
public var printTimer:Timer=new Timer(500); //might have to tweak this value for slower connections?
public function callPrint():void{
       printTimer.addEventListener(TimerEvent.TIMER,okayNowPrint);
    printTimer.start();
public function okayNowPrint(evt:TimerEvent):void{
var printJob:FlexPrintJob = new FlexPrintJob();
if (printJob.start()){
printJob.addObject(this,FlexPrintJobScaleType.SHOW_ALL);
printJob.send();
parentApplication.removeChild(this);
evt.currentTarget.stop();
printTimer.reset();

STILL doesn't work--this is baffling me.  Is it possibly because my print component is a VBox???
Here is my code:
private var ldr:Loader = new Loader();
private var urlReq:URLRequest = new URLRequest('logos/printHeader.jpg');
public function init():void{  //called by creationComplete
ldr.load(urlReq);
ldr.contentLoaderInfo.addEventListener( Event.COMPLETE, loaded);
private function loaded(event:Event):void{
trace("printHeader loaded");
printHeader.source=ldr;
callPrint();
public function callPrint():void{
var printJob:FlexPrintJob = new FlexPrintJob();
if (printJob.start()){
printJob.addObject(this,FlexPrintJobScaleType.SHOW_ALL);
printJob.send();
parentApplication.removeChild(this);
It's something to do with the fact that callPrint gets called early, for some reason.  Only by microseconds, but the image is always blank, even though if I make the component visible it appears almost simultaneously with the print dialog (but NOT immediately).
