itext jsp页面打印 android

最近项目中需要一个打印功能，需求很简单，只要打印出单据就可以了，画出一个表格，一些信息需要从数据库中提取

找到了免费的itext，可以实现我的简单的功能了

代码：（打印方法）

public String createPDF(HttpServletRequest request, HttpServletResponse response, String billCode,String comm) {
 Rectangle  rectangle = new Rectangle((float) 663.14 , (float) 370.7);
    Document document = new Document(rectangle,40,50,22,10);// 建立一个Document对象
    //Document document=new Document(PageSize.A4,36,36,36,36);
    //document.setPageSize(PageSize.A4);// 设置页面大小
    //String billCode = "20121026181";

    try {
     ByteArrayOutputStream ops = new ByteArrayOutputStream();//输出到客户段的流
     //OutputStream ops=new FileOutputStream("e:/taony125-test.pdf");//保存进磁盘的流
     //两个ops输出流用来切换，是保存进磁盘还是输出到客户端
