Steps to reproduce the problem:
1. The Flash player included with Chrome OS fails to display the system level print dialog when the start function is called on the print job when using either mx.printing.FlexPrintJob or flash.printing.PrintJob

Sample piece of Code from Reflex that should show the print dialog immediately on job.start()

import mx.printing.FlexPrintJob; 
import mx.controls.Alert;
import flash.events.Event;

private printSomething():void
{
var job: FlexPrintJob = null;

try
{
      job = new FlexPrintJob();
}
catch(err:Error)
{     
// shown an mx.Alert and then return.
Alert.show(“Error: “ + err.message, "Print Error",  Alert.OK, this, handleAlertClosed);                          
      return;
}

try
{
      if (job.start())
      {
            // this should have shown the system level print job dialog. That does not occur
            // on Chrome OS.
}
}
catch(err:Error)
{
// shown an mx.Alert and then return.
Alert.show(“Error: “ + err.message, "Print Error",  Alert.OK, this, handleAlertClosed);
                }
}

private function handleAlertClosed(pEvent:Event):void
{
                // do something here
}

What is the expected behavior?
The print dialog should launch, leading to being able to print from our flash application

What went wrong?
The print dialog does not launch.
