Java调用PDFBox打印自定义纸张PDF

PageFormat

默认PDFPrintable无法设置页面大小.

         PDFPrintable printable = new PDFPrintable(document);

         PrinterJob job = PrinterJob.getPrinterJob();

         job.setPrintable(printable);

需要把它放到一个Book中, 再设置即可

         Book book = new Book();

         book.append(printable, pageFormat);

         printerJob.setPageable(book);

         printerJob.print();

设置纸张属性

         Paper paper = new Paper();

         paper.setSize(width, height);

         // 设置边距

         paper.setImageableArea(marginLeft, marginRight, width - (marginLeft + marginRight), height - (marginTop + marginBottom));

         // 自定义页面设置

         PageFormat pageFormat = new PageFormat();

         // 设置页面横纵向

         pageFormat.setOrientation(PageFormat.PORTRAIT);

         pageFormat.setPaper(paper);

注意: 这边计量单位都是在dpi 72下的尺寸.

如果拿到是mm, 需要转为px. 例如10mm转换

10 * 72 * 10 / 254 = 28px

如果打印出现了截断, 一般是因为没有添加自定义纸张导致的.

参考 Java读取打印机自定义纸张.

完整代码如下

         InputStream in = new FileInputStream("d:\\a3.pdf");

         PDDocument document = PDDocument.load(in);

         PDFPrintable printable = new PDFPrintable(document, Scaling.ACTUAL_SIZE);

         PrinterJob printerJob = PrinterJob.getPrinterJob();

         PaperSize a3 = PaperSize.PAPERSIZE_A3;

         // A3 纸张在72 dpi下的宽高 841 * 1190

         int width = a3.getWidth().toPixI(72);

         int height = a3.getHeight().toPixI(72);

         // 10mm边距, 对应 28px

         int marginLeft = 28;

         int marginRight = 28;

         int marginTop = 28;

         int marginBottom = 28;

         Paper paper = new Paper();

         paper.setSize(width, height);

         // 设置边距

         paper.setImageableArea(marginLeft, marginRight, width - (marginLeft + marginRight), height - (marginTop + marginBottom));

         // 自定义页面设置

         PageFormat pageFormat = new PageFormat();

         // 设置页面横纵向

         pageFormat.setOrientation(PageFormat.PORTRAIT);

         pageFormat.setPaper(paper);

         Book book = new Book();

         book.append(printable, pageFormat);

         printerJob.setPageable(book);

         printerJob.print();
