Set print Size problem?

1

There is an output that fits in A4 papersize with a resolution of 827x1169px. I trigger a print function via Flash AS3

///Print Functions
var printArea:Rectangle = new Rectangle(0, 0, 827, 1169);
var pjoptions2:PrintJobOptions = new PrintJobOptions ();
pjoptions2.printAsBitmap = true;
var pj2:PrintJob = new PrintJob();
pj2.start();

pj2.addPage( this, printArea, pjoptions2);
pj2.send();

But the printout does not fit on A4 paper size (it tries to print larger and can see only a small portion on the paper). How can I arrange this with AS3?

Thanks in advance.
