I have problem to make a printPreview of a long html table. The problem
appears when the table takes more than one page. No problem when the table
fits in a page. I am using JTaxtPane, a class that extends HTMLDocument, and
Printable interface. I have implemented the following print() method:



        public int print(Graphics pg, PageFormat pageFormat,

           int pageIndex) throws PrinterException {

            pg.translate((int)pageFormat.getImageableX(),

              (int)pageFormat.getImageableY());

            int wPage = (int)pageFormat.getImageableWidth();

            int hPage = (int)pageFormat.getImageableHeight();

            pg.setClip(0, 0, wPage, hPage);



            // Only do this once per print

            if (m_printView == null) {

              BasicTextUI btui = (BasicTextUI)m_editor.getUI();

              View root = btui.getRootView(m_editor);

                m_printView = new PrintView(

                    m_doc.getDefaultRootElement().getElement(0),

                    root, wPage, hPage);

            }



            boolean bContinue = m_printView.paintPage(pg,

              hPage, pageIndex);

            System.gc();



            if (bContinue)

              return PAGE_EXISTS;

            else {

              m_printView = null;

              return NO_SUCH_PAGE;

            }

          }

where m_editor is JTextPane, m_doc is HTMDocument
