在一次系统优化过程中，卸载掉驱动．后来在重新使用自己的佳能IP1200打印机时遇到了这个问题，打印机驱动无法安装 安装设备时,出现了一个错误 RPC 服务器不可用"RPC服务器不可用"，一开始老以为是RPC服务没有启动，在管理工具，服务里查看服务的时候，也确实没有启动，改为自动模式，重启，还是不能够安装．检查后发现是“Print Spooler”服务的问题，因为不管是实际打印机和虚拟打印机都必须有这个服务，也必须启动才能够正常进行打印。
这个服务如果机器上面已经没有了，我们用代码的形势把它添加进注册表，从而增加这个服务．
使用方法，把下面代码复制到记事本文件，然后改名后缀为．REG注册表文件，双击运行即可，下面我也放了一个直接的REG文件，有需要的朋友可以下载使用．
