Printing images in Flex

Question

In s Flex 3 app, I have canvas with a PNG image for a background. The image is the same width & height as the canvas. I also have some other controls in the canvas:

<mx:Canvas id="form" backgroundImage="@Embed(source='images/formBkg.png')" width="640" height="480" >
    <mx:label .../>
    <mx:label .../>

I print the canvas using the following code:

var printJob:FlexPrintJob = new FlexPrintJob();

if (printJob.start())
{
    printJob.addObject(form, FlexPrintJobScaleType.SHOW_ALL);
    printJob.send();
}

On screen it looks great, but when I print it the quality of the png degrades. It is not terrible, but not as sharp as what is shown on screen.

Is there anything I can do to improve the quality of the printed png?

Flex doesn't do a great job at printing (caveman approach of creating a big image and shove it in the printer). you should consider external libraries such as AlivePDF
