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

package{

import flash.display.Sprite;

import flash.printing.PrintJob;

import flash.printing.PrintJobOptions;

import flash.printing.PrintJobOrientation;

import flash.geom.Rectangle;

import flash.events.MouseEvent;

public class BasicPrintExample extends Sprite{

private var myPrintJob:PrintJob = new PrintJob();

private var mySprite:Sprite = new Sprite();

private var options:PrintJobOptions = new PrintJobOptions();

private var rect1:Rectangle = new Rectangle(0,0,400,200);

public function BasicPrintExample(){

addChild(mySprite);

mySprite.addChild(mc);

btn.addEventListener(MouseEvent.CLICK, btnClick);

}

private function btnClick(e){

printJob();

}

private function printJob(){

options.printAsBitmap = true;

myPrintJob.start();

myPrintJob.addPage(mySprite,rect1,options);

myPrintJob.send();

}

}

}

多页打印代码

[java] view
plaincopy

package {

//多页打印类

import flash.display.MovieClip;

import flash.printing.PrintJob;

import flash.printing.PrintJobOrientation;

import flash.display.Stage;

import flash.display.Sprite;

import flash.text.TextField;

import flash.geom.Rectangle;

import flash.events.MouseEvent;

public class PrintMultiplePages extends MovieClip {

private var sheet1:Sprite;

private var sheet2:Sprite;

private var sheet3:Sprite;

public function PrintMultiplePages() {

// constructor code

init();

btn.addEventListener(MouseEvent.CLICK, btnClick);

}

private function btnClick(e):void{

printPages();//打印

}

private function init():void{

sheet1 = new Sprite();

createSheet(sheet1, "Once upon a time...",{x:10, y:50, width:80, height:130});

sheet2 = new Sprite();

createSheet(sheet2, "There was a great story to tell, and it ended quickly.\n\nThe end.", null);

sheet3 = new Sprite();

createSheet(sheet3, "你好，打印第三页！",null);

}

private function createSheet(sheet:Sprite, str:String, imgValue:Object):void{

sheet.graphics.beginFill(0xeeeeee);

sheet.graphics.lineStyle(1,0x000000);

sheet.graphics.drawRect(0,0,100,200);

sheet.graphics.endFill();

var txt:TextField = new TextField();

txt.height = 200;

txt.width = 100;

txt.wordWrap = true;

txt.text = str;

if(imgValue != null){

var img:Sprite = new Sprite();

img.graphics.beginFill(0x0066cc);

img.graphics.drawRect(imgValue.x, imgValue.y, imgValue.width, imgValue.height);

img.graphics.endFill();

sheet.addChild(img);

}

sheet.addChild(txt);

}

private function printPages():void{

var pj:PrintJob = new PrintJob();

var pagesToPrint:uint = 0;

if(pj.start()){

if(pj.orientation == PrintJobOrientation.LANDSCAPE){

throw new Error("Page is not set to an orientation of portrait.");

}

sheet1.height = pj.pageHeight;

sheet1.width = pj.pageWidth;

sheet2.height = pj.pageHeight;

sheet2.width = pj.pageWidth;

sheet3.height = pj.pageHeight;

sheet3.width = pj.pageWidth;

try{

pj.addPage(sheet1);

pagesToPrint++;

}catch(e:Error){

//响应错误

}

try{

pj.addPage(sheet2);

pagesToPrint++;

}catch(e:Error){

//响应错误

}

try{

pj.addPage(sheet3);

pagesToPrint++;

}catch(e:Error){

//响应错误

}

if(pagesToPrint>0){

pj.send();

}

}

}

}

}
