java 指定打印机 进行打印

代码如下：

[java] view
plaincopy

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");

}

}

}
