在管理工具-服务里找不到print spooler这一项怎么办呢?安装打印机时会提示"系统缺少资源,打印子系统不可用",最好的解决方法如下:         1．看你的系统文件C:\WINDOWS\SYSTEM32文件中有没有spoolsv.exe程序．该程序大概是50K左右，如果没有或者被病毒破坏了，请从系统盘或其它电脑系统文件拷贝粘贴到c:\windows\system32目录下面（此处c:/为系统盘符）。    2．打开记事本程序,将下面一段字符粘贴进去,然后另存为*.reg,再双击该文件,将该文件导入注册表,最后重新启动电脑即可.Windows Registry Editor Version 5.00* t!
