Emmeran Seehuber commented on PDFBOX-2682:
------------------------------------------
My workaround for now is to render the pages to an image and then print that
image.
{code}
final PDDocument document = PDDocument.load(new ByteArrayInputStream(pdfData));
final PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setJobName(jobName);
printJob.setPrintService(printer);
final PDFPrinter pdfPrinter = new PDFPrinter(document, printJob);
if (!MacUISetup.isMac()) {
pdfPrinter.silentPrint();
} else {
final Pageable pageable = pdfPrinter.getPageable();
final PDFRenderer pdfRenderer = new PDFRenderer(document);
printJob.setPageable(new Pageable() {
@Override
public int getNumberOfPages() {
return pageable.getNumberOfPages();
}
@Override
public PageFormat getPageFormat(int pageIndex) throws
IndexOutOfBoundsException {
return pageable.getPageFormat(pageIndex);
}
@Override
public Printable getPrintable(int pageIndex) throws
IndexOutOfBoundsException {
return new Printable() {
@Override
public int print(Graphics graphics, PageFormat
pageFormat, int pageIndex)
throws PrinterException {
if (pageIndex < 0 || pageIndex >=
document.getNumberOfPages()) {
return NO_SUCH_PAGE;
}
float dpi = 600;
try {
BufferedImage image =
pdfRenderer.renderImageWithDPI(pageIndex, dpi,
ImageType.RGB);
// Render the image
Graphics2D printerGraphics =
(Graphics2D) graphics;
printerGraphics.setBackground(Color.WHITE);
printerGraphics.translate(pageFormat.getImageableX(),
pageFormat.getImageableY());
printerGraphics.scale(
pageFormat.getImageableWidth() / (double) image.getWidth(),
pageFormat.getImageableHeight() / (double) image.getHeight());
printerGraphics.drawImage(image, 0, 0, null);
} catch (IOException e) {
e.printStackTrace();
}
return PAGE_EXISTS;
}
};
}
});
printJob.print();
}
document.close();
{code}
This works for me, but the printed image does not look as sharp as printed
vector shapes do ... On all other platforms I just use silentPrint() and
everything is fine.
I did not use the PDFPrinter dpi argument, because the image was clipped when
printed out. (Something is wrong with the scaling in this case).
