打印命令不会出现任何对话框，而是直接进行打印，不论按照之前的设置或者是标准的通常设置。
The print command would not issue any dialog but would just go ahead and print, either using previous settings or standard, vanilla settings.
例如在许多程序中，当用户请求打印时使用打印对话框指定打印多少页、打印多少份、向哪一台打印机输出，以及其他与打印功能相关的设置。
After a user asks to print, we don't have to ask him how many copies he wants or whether the image is landscape or portrait.
将该控件用作选择打印机和打印相关设置的简单解决方案，而不用配置您自己的对话框。
Use it as a simple solution for printer and print-related Settings selection in lieu of configuring your own dialog box.
