Need to print a pdf on button click

Question

Hi,
I need to do something similiar to what the code is doing below, except I need to create a button that when clicked will print a pdf. Not sure if it is better(easier) to add the pdf to my library and print that way or just upload the pdf to the server and print that.
anyway here is the code I have sofar. Not sure exavtly what I need to change/modify.
package com.wiley.as3bible.printing {
    import flash.display.Sprite;
    import flash.text.TextField;
    import flash.text.TextFieldAutoSize;
    import flash.net.URLLoader;
    import flash.net.URLRequest;
    import flash.events.Event;
    import flash.printing.PrintJob;
    import flash.display.SimpleButton;
    public class Printing extends Sprite {
        private var _printableContent:Sprite;
        private var _textField:TextField;
        private var _loader:URLLoader;
        public function Printing() {
            //Load the text from a text file
            _loader = new URLLoader();
            _loader.load(new URLRequest("http://www.rightactionscript.com/samplefiles/lorem_ipsum.txt"));
            _loader.addEventListener(Event.COMPLETE, completeHandler);
            //Create a multiline text field that autosizes.
            _textField = new TextField();
            _textField.width = 400;
            _textField.multiline = true;
            _textField.wordWrap = true;
            _textField.autoSize = TextFieldAutoSize.LEFT;
            //Create a sprite container for the text field,
            //and add the text field to it.
            _printableContent = new Sprite();
            addChild(_printableContent);
            _printableContent.addChild(_textField);
        //When the text loads add it to the text field and  then print the text
        private function completeHandler(event:Event):void {
            _textField.text = _loader.data;
            var printJob:PrintJob = new PrintJob();
            if (printJob.start()) {
                printJob.addPage(_printableContent);
                printJob.send();
I know the button code should be something like:
Printbtn.addEventListener(MouseEvent.CLICK,startPrint);
thanks in advance for any help.

I see what you are saying. I think I am going about this the wrong way. Really all I need is to upload the pdf to the server, since it is already created, and then in AS3 create a link that will be clickable and will download the pdf, in which case they can just print the download. I know how to do this in HTML, but not AS. Basically, it needs to be the equivalent of <a href="PathtoPDF_File">Click to download file</a>.
also I have a message window already coded, and within this message window is where I need to add the link:
package exam {
    import flash.display.*;
    import flash.events.*;
    import flash.text.*;
    //this class is used to create a "pop-up" window to ask users to confirm they want to exit (after clicking
    //exit exam button), and then to report back on how the submission went, and offer to resend if necessary
    public class MessageWindow extends Sprite {
        //VARIABLES
        private var feedback:TextField;
        private var confirm:YesBtn;
        private var quit:CancelBtn;
        private var resend:ResendBtn;
        public function MessageWindow (type:String, unanswered:Number=0, score:Number=0) {
            var bg:Shape = new Shape();
            bg.graphics.beginFill(0xffffff,1);
            bg.graphics.lineStyle(3,0x6fc9f4);
            bg.graphics.lineTo(400,0);
            bg.graphics.lineTo(400,250);
            bg.graphics.lineTo(0,250);
            bg.graphics.lineTo(0,0);
            bg.graphics.endFill();
            addChild(bg);
            var format:TextFormat = new TextFormat();
            format.font = "Verdana";
            format.size = "22";
            format.bold = false;
            format.color = 0x464646;
            feedback = new TextField();
            feedback.width = 300;
            feedback.x = 50;
            feedback.y = 15;
            feedback.wordWrap = true;
            feedback.autoSize = TextFieldAutoSize.LEFT;
            feedback.mouseEnabled = false;
            if (type == "confirm") {
                feedback.text = "Are you sure you want to exit the exam?";
                if (unanswered > 0) {
                    feedback.appendText("  You still have "+unanswered+" unanswered questions.");
                feedback.setTextFormat(format);
                addChild(feedback);
                quit = new CancelBtn();
                quit.setType("cancel");
                quit.x = 25;
                quit.y = this.height - (quit.height + 15);
                addChild(quit);
                confirm = new YesBtn();
                confirm.setType("confirm");
                confirm.y = quit.y;
                confirm.x = this.width - (confirm.width + 25);
                addChild(confirm);
            }else if (type == "success") {
                feedback.text = "Congrats on finishing the exam!\r\nYour score is "+Math.round(score*100)+"%\r\nYou may now close the exam window.";
                feedback.setTextFormat(format);
                addChild(feedback);
            }else {
                if (type == "databaseError") {
                    feedback.text = "Errors occured while saving your data.  Please retry.";
                }else if (type == "networkError") {
                    feedback.text = "Could not contact the server.  Please make sure you are connected to the internet and try again.";
                feedback.setTextFormat(format);
                addChild(feedback);
                resend = new ResendBtn();
                resend.setType("resend");
                resend.x = 200-(resend.width/2);
                resend.y = this.height - (resend.height + 15);
                addChild(resend);
in the else if(type =="success") part in the feedback.text ="" is where I need the link to go.
