How do I print?

Hi,

I would like to print an image that is on my app, how do I get access to the printer with an app made with Air SDK?
Is this code still working?:

var pj:PrintJob = new PrintJob();
var started:Boolean = pj.start2(null, false);
if(started)
{
     pj.addPage(this);
     pj.send();
};
pj = null;

I would like to print on Android and iOS too.
