在WindowsNT4 中，视频、服务器和打印机后台处理程序子系统被移动到内核模式。
In Windows NT 4, the video, server, and printer spooler subsystems were moved into kernel mode.
即便可以将多台打印机连接到网络，也通常使用一个服务器作为后台处理程序，该服务器然后通过网络打印到打印机。
Even though printers can be attached to the network, a server is usually used as the spooler, which in turn prints to the printer over the network.
当多个客户端都配置同一台打印机时，它们通常通过一个名为后台处理程序(spooler)的服务来完成配置。
When multiple clients have the same printer configured, they generally do so through a service called a spooler.
