[英]Print HTML File in Java
我需要从Java应用程序中打印HTML文件。 我尝试了几种方法。 其中两个正在工作,但未达到预期。
方法1:
问题:四分之三的纸张被裁切。
try {
PrinterJob printJob = PrinterJob.getPrinterJob();
PageFormat pageFormat = new PageFormat();
pageFormat.setOrientation(PageFormat.LANDSCAPE);
Paper paper = new Paper(); // Set to A4 size.
paper.setSize(594.936, 841.536); // Set the margins.
paper.setImageableArea(0, 0, 594.936, 841.536);
pageFormat.setPaper(paper);
XHTMLPanel panel = new XHTMLPanel();
panel.setDocument(new File("./documents/" + "Personalstamm"
+ ".html"));
printJob.setPrintable(new XHTMLPrintable(panel), pageFormat);
if (printJob.printDialog()) {
printJob.print();
}
} catch (Exception x) {
x.printStackTrace();
}
方法2:
问题:打印输出未在HTML文件中设置样式表。
PageFormat pageFormat = new PageFormat();
Paper a4paper = new Paper();
double paperWidth = 8.26;
double paperHeight = 11.69;
a4paper.setSize(paperWidth * 72.0, paperHeight * 72.0);
/*
* set the margins respectively the imageable area
*/
double leftMargin = 0.78; /* should be about 2cm */
double rightMargin = 0.78;
double topMargin = 0.78;
double bottomMargin = 0.78;
a4paper.setImageableArea(leftMargin * 72.0, topMargin * 72.0,
(paperWidth - leftMargin - rightMargin) * 72.0, (paperHeight
- topMargin - bottomMargin) * 72.0);
pageFormat.setPaper(a4paper);
pageFormat.setOrientation(PageFormat.LANDSCAPE);
DocumentRenderer documentRenderer = new DocumentRenderer(pageFormat,
"Report");
try {
FileInputStream stringReader = new FileInputStream(new File(
"./documents/" + "Personalstamm" + ".html"));
HTMLEditorKit htmlKit = new HTMLEditorKit();
HTMLDocument htmlDoc = (HTMLDocument) htmlKit
.createDefaultDocument();
htmlKit.read(stringReader, htmlDoc, 0);
documentRenderer.print(htmlDoc);
} catch (Exception x) {
x.printStackTrace();
}
有谁知道如何用这些方法之一解决问题? 还是有人有更好的方法从Java打印文件?
您不能使用CSS
打印HTML
。 最好的选择就是使用PDFs
,这就是它们的用途。 使用Java从HTML创建PDF并打印
现在我正在使用Apache PDFBox-一个Java PDF库 ,这几乎是我想要的。
我的代码:
public void printFile(String fileName) {
//Convert to PDF
try {
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(new File("./documents/html/"+fileName+".html"));
renderer.layout();
String fileNameWithPath = "./documents/pdf/"+fileName+".pdf";
FileOutputStream fos = new FileOutputStream(fileNameWithPath);
renderer.createPDF(fos);
fos.close();
} catch (Exception x) {
x.printStackTrace();
}
//Print with Dialog
try {
PrinterJob printJob = PrinterJob.getPrinterJob();
PageFormat pageFormat = new PageFormat();
pageFormat.setOrientation(PageFormat.LANDSCAPE);
Paper paper = new Paper();
paper.setSize(595, 842);
paper.setImageableArea(0, 0, 595, 842);
pageFormat.setPaper(paper);
PDDocument doc = PDDocument.load(new File("./documents/pdf/"+fileName+".pdf"));
printJob.setPrintable(new PDPageable(doc), pageFormat);
if (printJob.printDialog()) {
printJob.print();
}
doc.close();
} catch (Exception x) {
x.printStackTrace();
}
}
使用Jasper Reports可以解决问题。
