  /*用java实现打印 ,java.awt中提供了一些打印的API,
  要实现打印 ,首先要获得打印对象 ,然后继承Printable实现接口方法print ,以便打印机进行打印 ,
  最后用用Graphics2D直接输出直接输出 。
  下面代码实现了简单的打印功能:

  /*这个例子实现了打印字符串 ,线 (包括虚线 )和打印图片 。而且通过Paper的setImageableArea可以设置打印的区域和边距 ,
  让开发者随意的设置打印的位置 。
  下面的打印代码没有设置打印区域 ,默认为打印纸张的区域和边距 ,比如我们一般用的A4纸 ,打印的起点X和Y坐标则是72 ,72。
  无区域设置的代码 :
