推荐答案

它取决于用户打印输出的方式。例如，如果用户在mspaint上获得打印屏幕并从中获取打印输出，则无法从ASP.NET获取此类案例的打印信息。

但是如果你的asp上有打印按钮.net网页，只要用户点击打印，您就可以使用打印详细信息将记录保存到数据库。

如果您需要知道从打印机中取出的所有打印输出的实际数量，那么您最好从打印机制造商处查询打印机可用的API或SDK方法。

另请查看以下代码项目与打印机作业和监视打印机猜测有关的文章

从VB.NET监控打印机队列 [ ^ ]

it depend on how users took printouts. for example if user get print screen and past it on mspaint and took printout from that, you can't get print information of such case from ASP.NET.
But if you have print button on your asp.net web page and you can save record to database with print details whenever user click print.
If you need to know actual count of all the printouts taken from your printer then you better check from printer manufacturer for such API or SDK methods available for your printer or not.
