TrueType fonts always appear filled in your drawing; however, when you plot, the TEXTFILL system variable controls whether the fonts are filled. By default TEXTFILL is set to 1 to plot the filled-in fonts. When you export a drawing to PostScript® format and print it on a PostScript device, the font is plotted as designed.
TrueType 字体在图形中始终显示为已填充；而在打印时，TEXTFILL 系统变量控制是否填充字体。默认情况下，TEXTFILL 设置为 1，从而打印以填充方式显示的字体。当用户将图形输出为 PostScript® 格式并在 PostScript 设备上对其进行打印时，将按照设计的样式打印字体。
