如果有人能解释如何解决这个问题，我将不胜感激！！你好，请原谅我的英语！！

一幅图像进一步解释了这种情况：

这不是您使用iText开具发票的方式。飞碟不支持PDF/A、可访问性，。。。阅读以了解如何使用iText。如果有人已经完成了从A到Z的所有工作，你为什么要重新发明轮子？@BrunoLowagie:为了节省成本？客户希望支付越来越少的费用，并能够提供可行的服务，成本必须低。几年前，我们要求报价（顺便说一句，pdfHTML还没有提供），我们必须支付的每PDF的价格简直太高了。当时没有商业案例。对我来说（实际上没有PDF/A），使用旧iText的XHTMLender在技术上仍然可以正常工作。@Kukeltje如果你想要永久许可证，低容量的成本很高。如果您按次使用付费，则每个文档的成本为美分。
