win7虚拟打印驱动开发注意事项
通过控制面板安装遇到以下问题：
错误1、提示“Printer driver was not installed. Operation could not be completed (error 0x00000002)”
错误2、没有任何提示，就是安装不上
最后还是在stackoverflow找到了解决办法，原话在此：
is your INF file correct?? do verify it using INFGate.exe and there should be no errors reported by the tool.
If the INF file is correct, then it must be a signature issue, please note that signing is required for windows64 bit drivers, but not for 32 bit drivers.
In order to sign your driver, first make a cat file using inf2cat.exe and then use sign tool to sign the catalogue file... all these tools come with winddk...
