I have written a colouring board/whiteboard app and it’s in use.

A small problem is just driving me bananas:

When a user has drawn a picture and printed it (PrintJob function)  
the drawing board is cleared. I don’t know why this is happening.

PrintJob code is: (the drawing is held in **\_root.canvas** )

> // PRINTING  
> this.print\_btn.onPress = function() {

var printit : printJob = **new PrintJob** ();  
if (printit.start()) {

var numPages:Number = 0;

if (printit. **addPage** (\_root.canvas,{xMin:0,xMax:750,yMin:0,yMax:575})) {  
numPages++;  
};

if (numPages \> 0) {  
printit.send(); // print page(s)  
}  
**delete** printit;

\_root.createEmptyMovieClip(“canvas”, 0);

} else {  
trace(“PrintJob.start() failed”);  
}  
}

Any A.S. gurus can help me out here ?:hangover:
