Printing Multiple PDFs from Java as a single print job (physical printing)

I would like to print multiple pdfs from java (using the java print service) in a single print job.

I would like to send multiple pdfs as a single job to the printer. This is so that all the documents in my 'batch' print together and are not interleaved with someone else's print jobs when I go pick them up from the printer.

A batch potentially consists of 1000s of print jobs.

I tried jpedal, but it does not support java.awt.print.Book

        Book book = new Book();
        PdfDecoder pdfDecoder = readFileApplyOptions("C:/Temp/singlepagetest.pdf", pageFormat);
        book.append(pdfDecoder, pageFormat);

        PdfDecoder pdfDecoderTwo = readFileApplyOptions("C:/Temp/printfax-test.pdf",pageFormat);
        book.append(pdfDecoderTwo, pageFormat);

        printJob.setPageable(book);
        printJob.print();

only prints out the first pdf. How do I print multiple pdfs in a single job?

readFileAndApplyOptions() basically creates a new PdfDecoder object and returns it.

I also tried Sun's PDFRenderer PDFRenderer in a similar fashion (using the Book object), but my code still only prints out the first page only.

Has anyone encountered a similar issue before? Is there a solution I might be missing?

Not Java specific, but I've experience of this one in C#. I solved it by printing each document to a file (programmatically equivalent to checking the "PrintToFile" checkbox on a print dialog), then concatenated each file into a memory stream, which I passed to the Win32 API printer spool in raw format (since the output to file was already correctly formatted by default).

You might be able to use a similar technique in Java

I met the same difficulties when printing at once several JPanels of a JTabbedPane, each on a separate page. I gather them in a Book but it only prints the first page.

The Book class works well (right number of pages), but I suppose the problem comes from setPageable. Since a Book is not a Printable, I made it, and it works !

Workaround:

  1. Design a PrintableBook class : extends Book, implements Printable

    public class PrintableBook extends Book implements Printable {
    Vector<Printable> pages;// NB: we assume pages are single

    public PrintableBook() {
        super();
        pages = new Vector<Printable>();
    }

    public void add(Printable pp) {
        append(pp, pp.getPageFormat());
        pages.add(pp);
    }

    public int print(Graphics g, PageFormat pf, int pageIndex) {
        if (pageIndex >= pages.size())
            return NO_SUCH_PAGE;
        else {
            Printable pp = pages.elementAt(pageIndex);
            return pp.print(g, pf, 0);
        }
    }
}

  2. Then use printJob.setPrintable( printableBook ) instead of setPageable

You should merge all of your pdf documents in one document using iText library and then print the merged document page by page.

AFAIK, you can't, multiple documents will be printed in multiple jobs.

A workaround could be join all the pdf into a single document and print them.
