print spooler

基本解释

As multiple people submit print jobs, the spooler stores the job to disk.
当多人提交打印作业时，后台处理程序将作业存储到磁盘。
Once the printer is unused, the spooler can send the job to the printer without fear of contention from other print jobs.
一旦打印机闲置，后台处理程序就可以将作业发送到打印机，而不必担心其他打印作业争用。
Windows can't open Add Printer. The local print spooler service is not running. Please restart the spooler or restart the machine.
好像是先前被偶删掉了，并且在服务中把它关掉。现在打开控制面板中的打印机想添加却显示出。
