Printing mc from loaded clip gives empty pages

programming flash
1

Hi all,

So I need to print a mc from a .swf that is loaded into another .swf.

However the print gives empty pages. The printing works fine when the swf is not loaded into another other swf.

So structure is:
main.swf (loades)
print.swf (swf that contains the mc to print)

print.swf works fine when run standalone in a browser.

I am using the printJob class. It does not seem to be a path problem… Any ideas?

mcPrint.onRelease = function() {
    this.gotoAndStop("out");
    var pj:PrintJob = new PrintJob();
    // Letter paper size
    pj.pageHeight = 730;
    pj.pageWidth = 550;
    if (pj.start()){
        tr.text = "WOOO!";
        pj.addPage("mcResultsAllPrint", {xMin:0,xMax:550,yMin:0,yMax:710});
        pj.addPage("mcResultsAllPrint", {xMin:0,xMax:550,yMin:700,yMax:1270});
        pj.addPage("mcResultsAllPrint", {xMin:0,xMax:550,yMin:1270,yMax:2150});
        pj.send();
    } else {
        tr.text = "Problem!";
    }
    delete pj;
};
