jacob Excel转PDF问题,列显示不全

利用jacob将Excel转换为PDF时，Excel中的列在PDF中显示不全.Excel的列有很多。
有什么方法可以改变纸张大小，或者缩小PDF内容？或者还要其他方法解决这个问题？

    public boolean excelTopdf(String inputFile, String pdfFile){

         ComThread.InitSTA();
         ActiveXComponent app = new ActiveXComponent("Excel.Application");
         app.setProperty("Visible", new Variant(false));
         Object excels = app.getProperty("Workbooks").toDispatch();
         Object excel = Dispatch.invoke(
                 (Dispatch) excels,
                 "Open",
                 Dispatch.Method,
                 new Object[] { inputFile, new Variant(false),
                         new Variant(true) }, new int[9]).toDispatch();


         Dispatch currentSheet = Dispatch.get((Dispatch) excel,
                 "ActiveSheet").toDispatch();


         Dispatch pageSetup = Dispatch.get(currentSheet, "PageSetup")
                 .toDispatch();
         Dispatch.put(pageSetup, "Orientation", new Variant(2));
         Dispatch.put(pageSetup, "Zoom", false); // 值为100或false
         Dispatch.put(pageSetup, "FitToPagesWide", 1); // 所有列为一页(1或false)



         Dispatch.call(currentSheet, "SaveAs", pdfFile,
                     new Variant(57));
             if (app != null) {
                 app.invoke("Quit", new Variant[] {});
                 app = null;
             }
             ComThread.Release();

        return true;

    }

你在excel模板中设置一下打印区域！
