当使用飞碟打印时,在prolog中不允许来自DOM创建的文档的内容

我想用我的飞碟打印一些文字( https://xhtmlrenderer.dev.java.net

DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder;
documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
Element html = document.createElement("html");
document.appendChild(html);
Element body = document.createElement("body");
html.appendChild(body);
for (String paragraph : paragraphs) {
    Element paragraphTag = document.createElement("p");
    paragraphTag.setTextContent(paragraph);
    body.appendChild(paragraphTag);
}
XHTMLPanel panel = new XHTMLPanel();
panel.setDocument(document);

print(new XHTMLPrintable(panel));

print方法获取一个Printable并将其放入PrintJob。
