1、利用IE直接打印，这种方式最方便，但是控制能力较差。
2、利用ACTIVE控件，可以自己做一个IE的控件来控制打印。
3、水晶报表等第三方工具，购买价格昂贵。
根据我的需求情况，用IE直接打印的方式可以满足。我们的目的就是在一张申请表格上对应位置打印上相应的项目，表格也只有一页，不涉及分页的问题。
先来看一下表格，目的就是在一个WEBFORM里面对应的TEXTBOX内容放到对应的位置打印出来。
先来说一下我的思路：程序自动生成一个要打印的网页，将对应的字段值传递给这个网页，每个字段的位置事先量好，利用<div style=" ">来控制对应字段在页面中的位置。具体要到了下面技术：
1、自定义一个打印类，用来自动生成要打印的网页。
using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Text; using System.IO; using System.Collections;
/// /// MyPrint 的摘要说明 /// public class MyPrint : System.Web.UI.Page { public static string pageUrlBase;//Page基本的URL public string name; public string sex; public string brithday; public string country; public string CardName; public string CardNum; public string address; public string touchAddress; public string tel; public string postCode; public string type; public string reg; public string oldReg; /// /// 恢复打印模板 /// /// ///
public void ClearView() { StringBuilder htmltext = new StringBuilder(); try { if (!File.Exists(Server.MapPath(Context.Request.ApplicationPath) + "//printwindow.htm")) { FileStream fs = File.Create(Server.MapPath(Context.Request.ApplicationPath) + "//printwindow.htm"); fs.Close(); } using (StreamWriter sw = new StreamWriter(Server.MapPath(Context.Request.ApplicationPath) + "//printwindow.htm",false,Encoding.Default)) { string sTableTitle = ""; sTableTitle = sTableTitle + "<html>/n"; sTableTitle = sTableTitle + "<head>/n"; sTableTitle = sTableTitle + "<Title></Title>/n"; sTableTitle = sTableTitle + "<meta http-equiv=/"Content-Type/" content=/"text/html; charset=GB2312/">/n"; sTableTitle = sTableTitle + "<script lanage=/"javascript/">"; sTableTitle = sTableTitle + "function preview()"; sTableTitle = sTableTitle + "{"; sTableTitle = sTableTitle + "window.print();window.close()}</script>"; sTableTitle = sTableTitle + "</head>";
sTableTitle = sTableTitle + "<body style=/"background-position: left top; background-image: url(Images/申请表.jpg); left: 0px; width: 735px; position: absolute; top: 0px; height: 1050px;/" ms_positioning=/"GridLayout/" topmargin=/"0/" bottommargin=/"0/" onload=/"preview();/">/n"; //sTableTitle = sTableTitle + "Model/n"; //正式页面内容部分 sTableTitle = sTableTitle + "<font face=/"宋体/">"; sTableTitle = sTableTitle + "<div Style=/"z-index: 100; left: 138px; position: absolute; top: 176px/">" + name + "</div>"; //sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 116; left: 119px; position: absolute; top: 439px/" Width=/"8px/" Height=/"8px/" />"; sTableTitle = sTableTitle + "<div Style=/"z-index: 101; left: 395px; position: absolute; top: 176px/">" + sex + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 102; left: 488px; position: absolute; top: 176px/">" + brithday + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 103; left: 640px; position: absolute; top: 176px/">" + country + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 104; left: 138px; position: absolute; top: 200px/">" + CardName + "</div>"; //sTableTitle = sTableTitle + "<div Style=/"z-index: 105; left: 272px; position: absolute; top: 200px/">" + CardNum + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 106; left: 136px; position: absolute; top: 256px/">" + address + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 107; left: 136px; position: absolute; top: 288px/">" + touchAddress + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 108; left: 136px; position: absolute; top: 320px/">" + tel + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 109; left: 472px; position: absolute; top: 320px/">" + postCode + "</div>"; sTableTitle = sTableTitle + "<div Style=/"z-index: 110; left: 352px; position: absolute; top: 352px/">" + reg + "</div>"; //sTableTitle = sTableTitle + "<div Style=/"z-index: 112; left: 119px; position: absolute; top: 358px/">姓名</div>"; //判断是否是初次申领还是什么地 if(type=="初次申领") sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 112; left: 128px; position: absolute; top: 358px/" Width=/"8px/" Height=/"8px/" />"; else if (type == "增加准驾车型") { sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 115; left: 118px; position: absolute; top: 384px/" Width=/"8px/" Height=/"8px/" />"; sTableTitle = sTableTitle + "<div Style=/"z-index: 111; left: 600px; position: absolute; top: 352px/">" + oldReg + "</div>"; } else if (type == "持军警驾驶证") { sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 114; left: 118px; position: absolute; top: 409px/" Width=/"8px/" Height=/"8px/" />"; sTableTitle = sTableTitle + "<div Style=/"z-index: 111; left: 600px; position: absolute; top: 352px/">" + oldReg + "</div>";
} else { sTableTitle = sTableTitle + "<img src=/"Images/1234.jpg/" Style=/"z-index: 116; left: 119px; position: absolute; top: 439px/" Width=/"8px/" Height=/"8px/" />"; sTableTitle = sTableTitle + "<div Style=/"z-index: 111; left: 600px; position: absolute; top: 352px/">" + oldReg + "</div>";
} //输出身份证 int length = CardNum.Length; int start = 272; for (int i = 0; i < length; i++) { sTableTitle = sTableTitle + "<div Style=/"z-index: 105; left: " + start.ToString() + "px; position: absolute; top: 200px/">" + CardNum.Substring(i,1) + "</div>"; start = start + 18; } sTableTitle = sTableTitle + "</body>/n"; sTableTitle = sTableTitle + "</html>/n"; sw.WriteLine(sTableTitle); sw.Flush(); sw.Close(); } } catch { Response.Write("<script>alert('读取文件出错！')</script>"); } }public MyPrint() { // // TODO: 在此处添加构造函数逻辑 // try { string urlSuffix = Context.Request.Url.Host; urlSuffix = urlSuffix + (Context.Request.Url.Port.ToString() == "" ? "" : ":" + Context.Request.Url.Port); urlSuffix = urlSuffix + (Context.Request.ApplicationPath.ToString() == "/" ? "" : Context.Request.ApplicationPath); pageUrlBase = @"http://" + urlSuffix; } catch {
} } }
ClearView函数是用来自动生成网页。里面输出身份证的时候，为了和表格对应精确采用了按位输出。
2.调用的方法
print.name = this.TextBox2.Text; if (RadioButton1.Checked) print.sex = "男"; else print.sex = "女"; print.brithday = this.TextBox4.Text; print.tel = this.TextBox5.Text; print.country = this.DropDownList2.Text; print.type = this.DropDownList3.Text; print.oldReg = this.DropDownList4.Text; print.reg = this.DropDownList6.Text; print.address = this.TextBox13.Text; print.touchAddress = this.TextBox14.Text; print.CardName = "身份证"; print.CardNum = this.TextBox3.Text;
print.ClearView(); string showOpen = "<script lanage='javascript'>window.open('printwindow.htm','_blank');</script>"; ScriptManager.RegisterClientScriptBlock(this.Button4, this.GetType(), "verygood", showOpen, false); 这是提交页面上的一个“打印”按钮的响应事件。首先把页面上对应的字段传给打印类，然后调用ClearView来生成网页。最后，通过注册脚本的方式在新窗口中打开网页。我这里了AJAX所以用到了
ScriptManager.RegisterClientScriptBlock(this.Button4, this.GetType(), "verygood", showOpen, false);这句，如果没用AJAX用这个就可以了
RegisterClientScriptBlock("clientScript", showOpen);
3、用到的JAVASCRIPT
<script language="Javascript"> function preview() { window.print(); self.close(); } </script>
打印之后能够自动关闭窗口。
