Question

I want to list down all available printers that are availble. I found this answer:
As3 List down the Printers that available in the system
But this doesn’t work, I’m getting this error:

Error: Access of possibly undefined property printers through a reference with static type Class.

this is my source:

package  
{
import flash.display.Sprite;
import flash.printing.PrintJob;
import flash.external.ExternalInterface;

public class gethwinfo extends Sprite
{

    public function gethwinfo() 
    {
        ExternalInterface.call('getPrinter', getPrinterList());
    }

    public function getPrinterList():Array
    {
        var printerList:Vector.<String> = PrintJob.printers;
        var deviceNames:Array = [];

        if (printerList)
        {
            for (var i:int = 0; i < printerList.length; i++)
            {
                deviceNames.push(printerList[i]);
            }
        } else
        {
            deviceNames.push("No Printers");
        }

        deviceNames.sort();
        return deviceNames;
    }   
}
}

The Error says that the property printers is undefined, although this property is listed in the as-reference: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/printing/PrintJob.html#printers

I get this error with strict mode set to true in the compiler options. When I set it to false the build is sucessfull, but when I call this flash object it goes into the else branch and I get the String “No Printers”, which should not be, because I have 6 printer services available on my machine.

I hope that you can give me a hint.

Answer 1

its only available in AIR. thats why the AIR icon is next to it in the as-reference.
