In addition, a page’s margin settings can be determined by comparing the page and paper dimensions, as the

following example illustrates:

margin_height = (myPrintJob.paperHeight - myPrintJob.pageHeight) / 2;

margin_width = (myPrintJob.paperWidth - myPrintJob.pageWidth) / 2;

Example: Multiple-page printing

When printing more than one page of content, you can associate each page of content with a different sprite (in this

case,

sheet1 and sheet2), and then use PrintJob.addPage() for each sprite. The following code illustrates this

technique:

package

{

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;

public class PrintMultiplePages extends MovieClip

{

private var sheet1:Sprite;

private var sheet2:Sprite;

public function PrintMultiplePages():void

{

init();

printPages();

}

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);

}

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(0xFFFFFF);

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;

try

{

pj.addPage(sheet1);

pagesToPrint++;

}

catch (error:Error)

{

// Respond to error.

}

try

{

pj.addPage(sheet2);

pagesToPrint++;

}

catch (error:Error)

{

// Respond to error.

}

if (pagesToPrint > 0)

{

pj.send();

}

}

}

}
