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*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...
