项目的Debug文件夹下有个template文件夹，里面有用到的js、自己建的要打印的网页和用到的背景图
1、打印方法：
class print
{
public void printzb(string bh){
//要打印的变量
string zwjyzsbh = "123456";
string zsfwdp = "";
string zsfwdc = "";
string zsfwdxian = "";
//获取打印背景图的地址
string pash="";
string pashimg="";
//这里用到了VelocityHelper模板
VelocityHelper vh = new VelocityHelper();
vh.Init(@"template");//初始化,指定模板文件的相对路径，就是工程里Debug文件里的路径
//put后，在网页就可以调用这些变量，就和spring的那一套流程类似,jsp通过jstl调用
vh.Put("title", "员工信息");
vh.Put("zwjyzsbh", zwjyzsbh);
vh.Put("zsfwdp", zsfwdp);
vh.Put("zsfwdc", zsfwdc);
vh.Put("zsfwdxian", zsfwdxian);
pash = Directory.GetCurrentDirectory();//工程的Debug所在目录
pash = pash.Replace("\\", "/");
pashimg = pash + "\\template\\JY_DYJY_SJZWJYZS.jpg";
pashimg=pashimg.Replace("\\", "/");
vh.Put("pash", pash);
vh.Put("pashimg", pashimg);
//新建窗体FrmWebBrowser，拉一个控件webBrowser，在该控件显示所要打印的页面page.htm
String htm = vh.Display("page.htm");
FrmWebBrowser frmView = new FrmWebBrowser();
frmView.webBrowser1.DocumentText = htm;
}
}
2、要显示的页面：page.htm，(自己新建一个)
<!DOCTYPE html>
<HTML>
<HEAD>
<TITLE>$title</TITLE>
<META http-equiv=Content-Type content="text/html; charset=UTF-8">
<META content="$title" name=description>
<META content="$title" name=keywords>
<script type="text/javascript" src="http://127.0.0.1:8000/CLodopfuncs.js"></script>
<script type="text/javascript" src="$pash/template/jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="$pash/template/bootstrap.min.js"></script>
<script type="text/javascript" src="$pash/template/jquery.bootstrap.js"></script>
<script type="text/javascript" src="$pash/template/jquery.form.js"></script>
<script type="text/javascript" src="$pash/template/jquery.validate.min.js"></script>
<script type="text/javascript" src="$pash/template/messages_bs_zh.js"></script>
<script type="text/javascript" src="$pash/template/LodopFuncs.js"></script>
<script>
$(function () {
LODOP = getLodop();
LODOP.NewPage();
LODOP.ADD_PRINT_TEXT(200, 150, 375, 22, "$zwjyzsbh");//（要打印的文本，前四个是坐标，最后是获取前面put的变量）
LODOP.ADD_PRINT_TEXT(170, 270, 75, 22, "$zsfwdp");
LODOP.ADD_PRINT_TEXT(170, 400, 75, 22, "$zsfwdc");
LODOP.ADD_PRINT_TEXT(170, 400, 75, 22, "$zsfwdxian");
LODOP.ADD_PRINT_SETUP_BKIMG("<img width=‘760‘ height=‘1122‘ border=‘0‘ src=‘$pashimg‘>");//增加背景图
LODOP.SET_SHOW_MODE("BKIMG_IN_PREVIEW", 1);//打印预览是否显示背景图，1：显示
LODOP.PREVIEW();//预览
});
</script>
</HEAD>
<body>
</body>
</HTML>

3、FrmWebBrowser窗体，用来显示要打印的页面
3、VelocityHelper模板类，用来生成html，需要引入NVelocity。不用改
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using NVelocity;
using NVelocity.App;
using NVelocity.Exception;
using NVelocity.Runtime;
using System.IO;
using Commons.Collections;
using NVelocity.Context;
namespace gjjy
{
class NVelocityHelper
{ ///
/// NVelocity模板工具类 VelocityHelper
///
public class VelocityHelper
{
private VelocityEngine velocity = null;
private IContext context = null;
///
/// 构造函数
///
///模板文件夹路径
public VelocityHelper(string templatDir)
{
Init(templatDir);
}
///
/// 无参数构造函数
///
public VelocityHelper() { ;}
///
/// 初始话NVelocity模块
///
///模板文件夹路径
public void Init(string templatDir)
{
//创建VelocityEngine实例对象
velocity = new VelocityEngine();
//使用设置初始化VelocityEngine
ExtendedProperties props = new ExtendedProperties();
props.AddProperty(RuntimeConstants.RESOURCE_LOADER, "file");
props.AddProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templatDir);
props.AddProperty(RuntimeConstants.INPUT_ENCODING, "utf-8");
props.AddProperty(RuntimeConstants.OUTPUT_ENCODING, "utf-8");
velocity.Init(props);
//为模板变量赋值
context = new VelocityContext();
}
///
/// 给模板变量赋值
///
///模板变量
///模板变量值
public void Put(string key, object value)
{
if (context == null)
context = new VelocityContext();
context.Put(key, value);
}
///
/// 显示模板
///
///模板文件名
public String Display(string templatFileName)
{
//从文件中读取模板
Template template = velocity.GetTemplate(templatFileName);
//合并模板
StringWriter writer = new StringWriter();
template.Merge(context, writer);
return writer.ToString();
}
}
}
}
4、检查电脑是否已安装Lodop
public bool checkLodop()
{
Microsoft.Win32.RegistryKey uninstallNode = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");
foreach (string subKeyName in uninstallNode.GetSubKeyNames())
{
Microsoft.Win32.RegistryKey subKey = uninstallNode.OpenSubKey(subKeyName);
object displayName = subKey.GetValue("DisplayName");
if (displayName != null)
{
//MessageBox.Show(displayName.ToString());
if (displayName.ToString().Contains("C-Lodop(32-bit)"))
{
return true;
//MessageBox.Show(displayName.ToString());
}
}
}
return false;
}
自动弹出安装界面
System.Diagnostics.Process.Start(Application.StartupPath + "\\" + "CLodopPrint_Setup_for_Win32NT_2.047.exe");
