Ejemplo de impresión: Impresión de varias páginas

Flash Player 9 y posterior, Adobe AIR 1.0 y posterior

Cuando se imprime más de una página de contenido, se puede asociar cada una de las páginas a un objeto Sprite distinto (en este caso, sheet1 y sheet2 ) y luego utilizar PrintJob.addPage() en cada uno de los objetos Sprite. El siguiente código muestra esta técnica:

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(); 
                } 
            } 
        } 
    } 
}
