If you are using a printer using the PostScript technology, you should install a description file for the printer (PostScript Printer Definition - PPD) so that you can utilise the specific printer features like paper tray selection, duplex print function and all built-in fonts. You can also use the generic printer driver since it contains the most important data and is suitable for most printers. In that case, you will have to do without the paper tray selection and must correctly set the page margins.
如果使用的是应用 PostScript 技术的打印机，则应为打印机安装一个说明文件（PostScript 打印机定义 - PPD），以便能利用特定的打印机功能，如纸盒选择、双面打印功能和所有内置字体等。也可以使用通用打印机驱动程序，因为它包含最重要的数据且适用于大多数打印机。使用这种驱动程序时，无需选择纸盒，但需要正确设置页边距。
