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

Question

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 printe

Answer 1

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 pages;// NB: we assume pages are single
   
       public PrintableBook() {
           super();
           pages = new Vector();
       }
   
       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
