本文提供了两个使用Java实现打印功能的例子。第一个例子展示了如何打印图片文件，包括设置打印属性和服务，以及通过对话框选择打印服务。第二个例子则演示了如何打印文本文件，包括异常处理。

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);
        }
    } 

}
