reader for the printer的意思|示意

If you need to use a media card reader or a particular printer, for instance, it's probably worth checking ahead of time whether the distros you're considering have worked with it before.

如果你需要使用读卡器或者特定的打印机，你可能需要花点时间查看你考虑的这款发行版本能使它们工作。

Under the covers, the code configures the simulator for the disk (where it loads the LISP interpreter), the card reader (where it reads the job), and the printer (where it emits the output).

在后台，代码为磁盘（在这里加载 LISP 翻译器）、读卡器（在这里读取作业）以及打印机（在这里产生输出）配置仿真器。
