How to print a PDF file created using iText?

Question

Hi, I created a PDF file with an image in it, I want to print a PDF after creating it. It is better if I have a PDF in memory instead of a file, and then send it to the printer ... Any idea?

I am using iText. Check out my code:

    import com.lowagie.text.Document;
    import com.lowagie.text.DocumentException;
    import com.lowagie.text.Image;
    import com.lowagie.text.PageSize;
    import com.lowagie.text.Rectangle;
    import com.lowagie.text.pdf.PdfContentByte;
    import com.lowagie.text.pdf.PdfPrinterGraphics2D;
    import com.lowagie.text.pdf.PdfTemplate;
    import com.lowagie.text.pdf.PdfWriter;

    import javax.imageio.ImageIO;

    import java.awt.Color;
    import java.awt.Graphics2D;
    import java.awt.Toolkit;
    import java.awt.image.BufferedImage;
    import java.io.ByteArrayInputStream;
    import java.io.File;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.io.InputStream;


        private boolean exportToPdfThroughPNG(String fileName, float width, float height) throws DocumentException, IOException {
        logger.debug("[boolean exportToPdfQuick() throws IOException, DocumentException]");

        BufferedImage pngFile = createPngFile();

        Document document = new Document();
        document.setPageSize(new Rectangle(width, height));
        PdfWriter.getInstance(document, new FileOutputStream(fileName));
        document.open();
        Image image = Image.getInstance(Toolkit.getDefaultToolkit().createImage(pngFile.getSource()), Color.WHITE);
        document.add(image);
        // If some day anyone wants to put text in the pdf. @Eduardo
        // document.add(new Paragraph("title of the process"));
        document.close();

        return true;
    }

Thanks in advance!

You can always use ByteArrayOutputStream instead of FileOutputStream.

Once you have the PDF bytes, this is the usual question "how do you print in Java." Nowadays, many printers (or at least their drivers) will receive PDF, so at this point you can say that everything is ready.
