我目前正在 Microsoft Windows 主机上测试将 RTF/DOC 文档转换为 PDF。我有一段使用 Microsoft Word API 的工作和平代码，但由于许可证成本，我想摆脱它。
我的想法是，只需将 RTF“发送”到 Microsoft Print To PDF 打印机，就可以将 RTF 转换为 PDF。
我遇到的问题是，我一方面可以访问打印机，也可以得到输出，但文件已损坏。
如果我只是将生成的文件从 .pdf 重命名为 .rtf 并在 Microsoft Word 中打开它，内容将如下所示（它只是整个内容的摘录）：

我假设我没有正确读取该文件。或者可能写得不正确？没有把握。
也许缺少一个属性——我只是认为这是错误的一件小事。
我有以下代码：

有谁知道为什么在使用上面的代码时无法使 Microsoft Print to PDF Printer 生成正确的 PDF？
任何提示将不胜感激。
非常感谢。
