java打印功能源代码 用java实现打印功能

IT技术json

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java打印功能源代码的可用打印服务
PrintService service = ServiceUI.printDialog(null, 500, 500, services, services[0], null, new HashPrintRequestAttributeSet());//创建一个默认java打印功能源代码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java打印功能源代码，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
谁有java打印的源代码//参考下吧
