Stampare immagini: esce il foglio bianco

[fermat]

si in effetti hai ragione.

allora, ho fatto un pò di pulizia, ma adesso escono solo pagine bianche:

public class PrintImage implements Printable {

    private BufferedImage[] images;

    public PrintImage(BufferedImage[] images) {
        this.images = images;
    }

    @Override
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
        if (pageIndex < images.length) {
            graphics.drawImage(images[pageIndex], 0, 0, images[pageIndex].getWidth(), images[pageIndex].getHeight(), null);
            return PAGE_EXISTS;
        } else {
            return NO_SUCH_PAGE;
        }
    }
}

e passo l'array così:

int lvSize = listViewImages.getItems().size();
if (lvSize > 0) {
    ArrayList<String> lp = new ArrayList<>(listViewImages.getItems());
    BufferedImage[] bufferedImages = new BufferedImage[lp.size()];
    for (int i = 0; i < lp.size(); i++) {
        Image image = new Image(new File(lp.get(i)).toURI().toString());
        bufferedImages[i] = SwingFXUtils.fromFXImage(image, null);
    }
    PrinterJob pj = PrinterJob.getPrinterJob();
    pj.setPrintable(new PrintImage(bufferedImages));
    if (pj.printDialog()) {
        try {
            pj.print();
        } catch (PrinterException e) {
            GenericDialog.showDialog(e.getMessage(), Alert.AlertType.ERROR);
        }
    }
}
