AS3使用PrintJob实现单页或多页打印

as3实现打印功能：

主要用到PrintJob类中的start()、addPage(mc:sprite,rect,option)、send()三个方法。

单页打印代码

[java] view plaincopy

1. package{  
2.       
3.     import flash.display.Sprite;  
4.     import flash.printing.PrintJob;  
5.     import flash.printing.PrintJobOptions;  
6.     import flash.printing.PrintJobOrientation;  
7.     import flash.geom.Rectangle;  
8.     import flash.events.MouseEvent;  
9.       
10.     public class BasicPrintExample extends Sprite{  
11.           
12.         private var myPrintJob:PrintJob = new PrintJob();  
13.         private var mySprite:Sprite = new Sprite();  
14.         private var options:PrintJobOptions = new PrintJobOptions();  
15.         private var rect1:Rectangle = new Rectangle(0,0,400,200);  
16.           
17.         public function BasicPrintExample(){  
18.               
19.             addChild(mySprite);  
20.             mySprite.addChild(mc);  
21.               
22.             btn.addEventListener(MouseEvent.CLICK, btnClick);  
23.         }  
24.           
25.         private function btnClick(e){  
26.             printJob();  
27.         }  
28.           
29.         private function printJob(){  
30.             options.printAsBitmap = true;  
31.             myPrintJob.start();  
32.             myPrintJob.addPage(mySprite,rect1,options);  
33.             myPrintJob.send();  
34.         }  
35.           
36.     }  
37. }  

多页打印代码

[java] view plaincopy

1. package  {

17.
