Printing 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();
				}
			}
		}
	}
}
