C#中的Printer Spooler，AddPrinterDriverEx函数答案

【问题标题】：Printer Spooler, AddPrinterDriverEx function in c#C#中的Printer Spooler，AddPrinterDriverEx函数
【发布时间】：2012-09-08 09:44:18
【问题描述】：

谷歌了很多，但空手而归..

我想知道是否有人在 c# 中使用 winspool.drv 使用 AddPrinterDriver 或 AddPrinterDriverEx API。

请提供初始化和使用此 API 调用的代码。

紧急..！！

我已经在同一问题上工作了一段时间，并且有一些东西要开始，尽管我仍然遇到问题。我相信我现在真正的问题是正确创建依赖文件列表。或许你知道如何为我填写这些空白？

谢谢，斯蒂芬
