『第 2 楼』:
使用 LLM 解释/回答一下
<转自管理员>其实有很多硬件设备在DOS下不需安装任何的驱动程序，只要硬件或将BIOS设置好就可使用，如键盘，普通的硬盘和支持PCL（打印机控制语言）的打印机等。在DOS下使用支持PCL的打印机非常容易，因为打印机连接在并行端口（LPT）上，所以通常LPT1或PRN就是打印机端口。比如COPY C:\CONFIG.SYS LPT1命令（当然也可直接使用PRINT C:\CONFIG.SYS命令）就可将C:\CONFIG.SYS文件中的内容用打印机打印出来。大家看，是不是很方便呢？当然，要在一些DOS应用程序中打印出更好的效果（如各种字体，图像等），还需要专门的打印机驱动程序，在这些应用程序中的“打印机设置”中选择合适的打印机即可。
<Transferred from the administrator>Actually, many hardware devices do not require installing any driver programs under DOS. As long as the hardware is set up or the BIOS is configured, they can be used, such as the keyboard, ordinary hard drives, and printers that support PCL (Printer Control Language), etc. Using a PCL-supported printer under DOS is very easy. Since the printer is connected to the parallel port (LPT), usually LPT1 or PRN is the printer port. For example, the command COPY C:\CONFIG.SYS LPT1 (of course, you can also directly use the PRINT C:\CONFIG.SYS command) can print the content of the C:\CONFIG.SYS file with the printer. Everyone, isn't it very convenient? Of course, to print better effects (such as various fonts, images, etc.) in some DOS applications, special printer driver programs are still needed. In the "Printer Settings" in these applications, select the appropriate printer.
