This is the code that you need to print something in flex.
<mx:Script>
<![CDATA[
import mx.printing.FlexPrintJob;
private function print():void {
// create print job
var printJob:FlexPrintJob = new FlexPrintJob();
if(printJob.start()){
// add page
printJob.addObject(myLabel,"none");
// send to printer
printJob.send();
}
}
]]>
</mx:Script>
where mylabel is a control you could add any display object that you want.
