使用Flex / ActionScript / Air打印和隐藏对话 - 找不到PrintUIOptions

Question

我想用flex / air打印 - 正常的打印对话工作..但是当我开始使用start2时，我得到以下错误：

$ grep '^[^[\s]*#]' infile
abc#] does not start with blank or [ and has #]
abc#]] does not start with blank or [ and has #]]
 abc#]] starts with blank and has #]]

这是我的班级：

/Users/myuser/Test2.as:9
Warning: Definition flash.printing.PrintUIOptions could not be found.
      import flash.printing.PrintUIOptions;
             ^

/Users/myuser/Test2.as:12
Error: Type was not found or was not a compile-time constant: PrintUIOptions.
      var uiOpt:PrintUIOptions = new PrintUIOptions();
                ^

/Users/myuser/Test2.as:12
Error: Call to a possibly undefined method PrintUIOptions.
      var uiOpt:PrintUIOptions = new PrintUIOptions();
                                     ^

/Users/myuser/Test2.as:15
Error: Call to a possibly undefined method start2 through a reference with static type PrintJob.
      var accepted:Boolean = myPrintJob.start2(uiOpt);
                                        ^

当我看到这个答案时，应该很容易：How to hide print dialog box in Flex?

我在网上找不到任何信息，也许某人对我有暗示？

编辑：我正在使用命令行中的命令编译整个事情：

package {

  import flash.display.Sprite;

  public class Test2 extends Sprite {

    public function Test2 () {
      import flash.printing.PrintJob;
      import flash.printing.PrintUIOptions;

      var myPrintJob:PrintJob = new PrintJob();
      var uiOpt:PrintUIOptions = new PrintUIOptions();
      uiOpt.minPage = 1;
      uiOpt.maxPage = 3;
      var accepted:Boolean = myPrintJob.start2(uiOpt);
    }
  }
}

编译与amxmlc一起运行正常，但是当我尝试打印文档时，我会遇到奇怪的异常。
