关于打印美签的那个页面

我现在正在打印美签的那个表格 有一个类似于证件的那个 带有条形码的那个我打印出来了 可是还有一个完整信息的那个 我就打印不出来了 print confirmation 那个我已经打印出来了 请问print application为什么就是打印不了？显示信息 ：Print Application Information
When you come for your interview, we ONLY need your printed Confirmation Page. Please do not bring the entire printed application to the Embassy or Consulate.

If you wish, you may choose to print the entire application for your own records. However, we strongly suggest that you keep your printed copy secure. Do not offer it to any other person, as this may compromise your personal information.
谢谢大家回答
