怎样用程序操作IE中工具栏(不是菜单)里的打印按钮?(active)

哈哈，JavaScript我也略知一二。
如果用Window.print()的话，其功能与菜单中的"打印"功能一样(MSDN语)，
而不是与工具栏上的“打印”按钮功能一样。
他们俩最大的区别就在于菜单里的"打印"要弹出一个选择打印机的对话框。
而工具栏上的“打印”按钮就是直接打印，不需要弹出一个选择打印机的对话框。
我现在需要的就是直接打印！万万不能弹出一个选择打印机的对话框!!!
所以我提了以上的问题!
如果用Java的话，请您说的更详细一些!
这是JDK DOC中的PrinterJob类，以下有许多方法，你可以看看.但如果你打算用这种方式实现就要用JSP了，呵呵Overview  Package   Class  Use  Tree  Deprecated  Index  Help
