用java实现打印功能 怎么写 求大神求源码
PrintService[] services = PrinterJob.lookupPrintServices();//查找系统中所有的可用打印服务
PrintService service = ServiceUI.printDialog(null, 500, 500, services, services[0], null, new HashPrintRequestAttributeSet());//创建一个默认的打印机选择对话框
DocPrintJob job = service.createPrintJob();//创建一个打印任务
Doc doc = new SimpleDoc(new FileInputStream(new File("D:\\image\\MM.jpg")), DocFlavor.INPUT_STREAM.JPEG, null);//创建一个打印的文档
job.print(doc, null);//打印
这是jdk提供的打印接口，你也可以找找其它的第三方类库，jdk提供打印接口功能一般般
求java实现票据套打印的源代码？
票据套打，这个大部分商业报表就可以实现。现在主流的商业报表多采用底图描绘，绝对定位的方式完成套打表样的绘制，用户可将要套打的票据扫描进来作为背景图，用报表设计器进行数据的位置摆放，可以精确定位数据的位置。你可以按你的要求试试，一般还是要自己操作一下容易记住，毛泽东说过的，实践出真知嘛！
