我有一个使用 c# 和 itext7 的 windows 形式的应用程序。我以 pdf 格式创建发票，并且 pdf 布局很好，但是当我发送要在点阵打印机 EPSON TM-U220 中打印的文件时，字体模糊，如下图所示：
生成pdf的整个codo是：FontProgram fontProgram = FontProgramFactory.CreateFont(fuente); PdfFont 字体 = PdfFontFactory.CreateFont(fontProgram);
//PdfFont font = PdfFontFactory.CreateFont(StandardFonts.COURIER, PdfEncodings.UTF8);
