代码如下：

package com.printer;
    
    import java.io.*;
    import java.util.Locale;
    
    import javax.print.*;
    import javax.print.attribute.*;
    import javax.print.attribute.standard.*;
    
    public class PrintTest {
    
    	public static void main(String args[]) {
    
    		FileInputStream psStream = null;
    		try {
    			psStream = new FileInputStream("D:\\work\\发票扫描件\\维修费20121025（发票联）.jpg");
    		} catch (FileNotFoundException ffne) {
    			ffne.printStackTrace();
    		}
    		if (psStream == null) {
    			return;
    		}
    		//设置打印数据的格式，此处为图片gif格式
    		DocFlavor psInFormat = DocFlavor.INPUT_STREAM.GIF;
    		//创建打印数据
    //		DocAttributeSet docAttr = new HashDocAttributeSet();//设置文档属性
    //		Doc myDoc = new SimpleDoc(psStream, psInFormat, docAttr);
    		Doc myDoc = new SimpleDoc(psStream, psInFormat, null);
    		
    		//设置打印属性
    		PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
    		aset.add(new Copies(3));//打印份数，3份
    		
    		//查找所有打印服务
    		PrintService[] services = PrintServiceLookup.lookupPrintServices(psInFormat, aset);
    
    		// this step is necessary because I have several printers configured
    		//将所有查找出来的打印机与自己想要的打印机进行匹配，找出自己想要的打印机
    		PrintService myPrinter = null;
    		for (int i = 0; i < services.length; i++) {
    			System.out.println("service found: " + services[i]);
    			String svcName = services[i].toString();
    			if (svcName.contains("Snagit 11")) {
    				myPrinter = services[i];
    				System.out.println("my printer found: " + svcName);
    				System.out.println("my printer found: " + myPrinter);
    				break;
    			}
    		}
    
    		//可以输出打印机的各项属性
    		AttributeSet att = myPrinter.getAttributes();
    
    		for (Attribute a : att.toArray()) {
    
    			String attributeName;
    			String attributeValue;
    
    			attributeName = a.getName();
    			attributeValue = att.get(a.getClass()).toString();
    
    			System.out.println(attributeName + " : " + attributeValue);
    		}
    
    		if (myPrinter != null) {
    			DocPrintJob job = myPrinter.createPrintJob();//创建文档打印作业
    			try {
    				job.print(myDoc, aset);//打印文档
    
    			} catch (Exception pe) {
    				pe.printStackTrace();
    			}
    		} else {
    			System.out.println("no printer services found");
    		}
    	}
    }
