JAVA代碼生成二維碼並調用打印機打印

jsp前端代碼：

<a href="javascript:void(0)" class="easyui-linkbutton" iconCls="icon-edit" plain="true" onclick="printTag()">打印條碼</a>

//打印
        function printTag() {
            var row = $('#dg').datagrid('getSelected');
            if (row) {
                $.messager.confirm('Confirm', '您確定要打印這條數據嗎?', function (r) {
                    if (r) {
                        var prodname =encodeURI(encodeURI(row.prodname));
                        $.post('${pageContext.request.contextPath}/service/product/print?prodno=' + row.prodno +"&prodname="+prodname, {}, function (data) {
                            if (data == 1) {
                                $('#dg').datagrid('reload');    // reload the user data
                            } else {
                                $.messager.show({    // show error message
                                    title: 'Error',
                                    msg: result.msg
                                });
                            }
                        }, 'json');
                    }
                });
            }
            else {
                $.messager.alert('提示', '請選擇你要打印的行!', '信息');
            }
        }

 

Controller代碼：

//打印
  @RequestMapping(value = "/print",method=RequestMethod.POST)
  public void print(String prodno,String prodname){
   if (prodno != null && prodname != null) {
    JbarcodeUtil.createBarcode(prodno, new File("F:/標簽.jpeg"),prodname);
    Print.print1();

   }
  }

 

 

 

util代碼：

package com.springmvc.util;

import java.io.File;
import java.io.FileInputStream;
import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;

import javax.print.ServiceUI;
import javax.print.SimpleDoc;
import javax.print.attribute.DocAttributeSet;

import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.swing.JFileChooser;

public class Print {
 public static void print1() {
  
   File file =  new File("F:/標簽.jpeg"); // 獲取選擇的文件
   // 構建打印請求屬性集
   HashPrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
   // 設置打印格式，因為未確定類型，所以選擇autosense
   DocFlavor flavor = DocFlavor.INPUT_STREAM.PNG;
   // 查找所有的可用的打印服務
   PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
   // 定位默認的打印服務
   PrintService defaultService = PrintServiceLookup
     .lookupDefaultPrintService();
   // 顯示打印對話框
   PrintService service = ServiceUI.printDialog(null, 100, 100, printService, defaultService, flavor, pras);
   if (service != null) {
    try {
     DocPrintJob job = service.createPrintJob(); // 創建打印作業
     FileInputStream fis = new FileInputStream(file); // 構造待打印的文件流
     DocAttributeSet das = new HashDocAttributeSet();
     Doc doc = new SimpleDoc(fis, flavor, das);
     job.print(doc, pras);
    } catch (Exception e) {
     e.printStackTrace();
    }
