try this

OleAutomation automation = new OleAutomation(clientSite);
        
        // looks up the ID for method Select.
        int[] methodIDs = automation.getIDsOfNames(new String[]{"PrintPreview"});
        int methodID = methodIDs[0];
        
        Variant result = automation.invoke(methodID);
        automation.dispose();

        } catch (org.eclipse.swt.SWTException e) {
          String str = "Create OleClientSite Error" + e.toString();
          System.out.println(str);
          return;
        }
        setSize(500, 500);
        validate();
        site.doVerb(org.eclipse.swt.ole.win32.OLE.OLEIVERB_SHOW);

Try this snippet and find out the exact function
http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/OLEandActiveXexamplesnippet.htm
and then use that function...

By the way ,to avoid all this version problems,u should open your PDF,word etc files in a browser..and from there you could print or print preview them easily.(unless u want word specific handling)

offcoarse there are many preconditions for this to work,but this approach avoids all the version specific handling and then again you already have a precondition of word should be installed on the system.. Smile
