JAVA实现连接本地打印机并打印文件的实现代码

实现代码一

import javax.print.*;
import javax.print.attribute.DocAttributeSet;
import javax.print.attribute.HashDocAttributeSet;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import java.io.File;
import java.io.FileInputStream;

public class PrintDemo1 {
  public void printPdf(String fileName) {
    //构造一个文件选择器，默认为当前目录
    File file = new File(fileName);//获取选择的文件
    //构建打印请求属性集
    PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
    //设置打印格式，因为未确定文件类型，这里选择AUTOSENSE
    DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
    //查找所有的可用打印服务
    PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
    //定位默认的打印服务
    //PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
    // 显示打印对话框
    PrintService service = ServiceUI.printDialog(null, 200, 200, printService, defaultService, flavor, pras);
    if (service != null) {

      try {
        DocPrintJob job = service.createPrintJob(); // 创建打印作业
        FileInputStream fis; // 构造待打印的文件流
        fis = new FileInputStream(file);
        DocAttributeSet das = new HashDocAttributeSet();
        Doc doc = new SimpleDoc(fis, flavor, das);
        job.print(doc, pras);
      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  }

  public static void main(String args[]) {
    PrintDemo1 pic = new PrintDemo1();
    pic.printPdf("F:\\java资源2\\Docker视频教程\\赠送3-从Docker到Kubernetes之技术实战\\01.为什么你需要学习Docker\\01.pdf");
  }

}

代码二

package com.iba.cxx.adm.controller;

import javax.print.*;
import javax.print.attribute.DocAttributeSet;
import javax.print.attribute.HashDocAttributeSet;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.swing.*;
import java.io.File;
import java.io.FileInputStream;

public class TestController {

  public static void main(String[] args) {
    JFileChooser fileChooser = new JFileChooser(); //创建打印作业
    int state = fileChooser.showOpenDialog(null);
    if(state == fileChooser.APPROVE_OPTION){
      // File file = new File("D:/haha.txt"); //获取选择的文件
      File file = fileChooser.getSelectedFile();//获取选择的文件
      //构建打印请求属性集
      HashPrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
      //设置打印格式，因为未确定类型，所以选择autosense
      DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
      //查找所有的可用的打印服务
      PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
      //定位默认的打印服务
      PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
      //显示打印对话框
      PrintService service = ServiceUI.printDialog(null, 200, 200, printService,
          defaultService, flavor, pras);
      if(service != null){
        try {
          DocPrintJob job = service.createPrintJob(); //创建打印作业
          FileInputStream fis = new FileInputStream(file); //构造待打印的文件流
          DocAttributeSet das = new HashDocAttributeSet();
          Doc doc = new SimpleDoc(fis, flavor, das);
          job.print(doc, pras);
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    }
  }
}
