http://forums.tweaktown.com/f18/lexbce-printer-spooler-21400/ Good solution, also mentioned by above Source – uses “sc” to modify service dependency of the print spooler.

Below command will reset the spooler service dependency to Remote Procedure Call service only.

sc config spooler depend= RPCSS 

You need the space after equal sign and before RPCSS = RPCSS. Also, you should know that The print spooler service dependencies are stored in the registry at HKEY_LOCAL_MACINE\SYSTEM\CurrentControlSet\Services\Spooler\DependOnService.
