Printing a canvas as a PDF (or otherwise) from a web page

That's great, Rod!

You can make use of the afterprint event and possibly the beforeprint event as well. Here is a sample:

var root = this;

root.setupPrint = function(e)
{
	root.yourPrintButton.visible = false;
};

root.print = function(e)
{
	window.print();
};

root.afterPrint = function(e)
{
    root.yourPrintButton.visible = true;
};

/* I'm using both mousedown and pressup events because if I use the same event for both, the print method it's called before the stage update */
root.yourPrintButton.on("mousedown", root.setupPrint);
root.yourPrintButton.on("pressup", root.print);
window.addEventListener("afterprint", root.afterPrint);

I hope it helps.
