javascript .print()-关闭默认打印机 [英] javascript .print() - turn off default printer

问题描述

Out系统使用javascript .print()，它会在选择默认打印机的情况下显示打印"对话框.有没有办法关闭默认打印机，以便在对话框出现时没有选择打印机，因此用户必须选择一个.

Out system uses the javascript .print(), which brings up the print dialog with the default printer selected. Is there a way to turn off the default printer so that when the dialog appears there is no printer selected so that the user has to select one.

我希望使用全局设置(例如web.config)，以便可以打开或关闭默认打印机.

I was hoping to use a global setting (e.g. web.config) so I could switch the default printer on or off.

有什么想法吗?
