Print打印机例证

Print打印机例子
例子一:

public class Test {/** * @param args */public static void main(String[] args) throws Exception {        File imageFile = new File("f:/1.png");        //打印作业的属性        PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();        //打印作业的格式，来源（PNG就换成.PNG就行了）        DocFlavor flavor = DocFlavor.INPUT_STREAM.JPEG;        //搜索所有可能的打印服务        PrintService[] services = PrintServiceLookup.lookupPrintServices(flavor, attributes);        System.out.println("services:"+services.length);                //搜索默认打印服务        PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();        //显示打印Dialog        PrintService service = ServiceUI.printDialog(null, 0, 0, services, defaultService, flavor, attributes);        //如果用户选择打印        if(service!=null){            //创建打印任务            DocPrintJob job = service.createPrintJob();            FileInputStream fis = new FileInputStream(imageFile);            //任务的属性            DocAttributeSet docAttributes = new HashDocAttributeSet();            Doc doc = new SimpleDoc(fis, flavor, docAttributes);            //打印            job.print(doc, attributes);        }    } }
