1：套打可能是以后软件开发可能会涉及到的功能，主要麻烦地方就是需要精确定位，光是打印发票还好，要是打印那种协议类型的特别麻烦，不仅长而且需要的数据多 ，定位麻烦。

2：而且大多数情况是需要去除页眉页脚的，一般使用的是activix来控制页眉页脚，以及边距的控制

3：然而activix操作注册列表是被ie浏览器安全控制所禁止的，我们需要将站点添加到信任站点中，并且在自定义级别中将有关activix使用都设为允许，就可以进行打印了

4：下面是网上找到的代码

var HKEY\_Root, HKEY\_Path, HKEY\_Key;  
HKEY\_Root = "HKEY\_CURRENT\_USER";  
HKEY\_Path = "\\\\Software\\\\Microsoft\\\\Internet Explorer\\\\PageSetup\\\\";  
var head, foot, top, bottom, left, right;  
  
  
//取得页面打印设置的原参数数据  
function PageSetup\_temp() \{  
try \{  
var Wsh = new ActiveXObject("WScript.Shell");  
HKEY\_Key = "header";  
//取得页眉默认值  
head = Wsh.RegRead(HKEY\_Root + HKEY\_Path + HKEY\_Key);  
HKEY\_Key = "footer";  
//取得页脚默认值  
foot = Wsh.RegRead(HKEY\_Root + HKEY\_Path + HKEY\_Key);  
HKEY\_Key = "margin\_bottom";  
//取得下页边距  
bottom = Wsh.RegRead(HKEY\_Root + HKEY\_Path + HKEY\_Key);  
HKEY\_Key = "margin\_left";  
//取得左页边距  
left = Wsh.RegRead(HKEY\_Root + HKEY\_Path + HKEY\_Key);  
HKEY\_Key = "margin\_right";  
//取得右页边距  
right = Wsh.RegRead(HKEY\_Root + HKEY\_Path + HKEY\_Key);  
HKEY\_Key = "margin\_top";  
//取得上页边距  
top = Wsh.RegRead(HKEY\_Root + HKEY\_Path + HKEY\_Key);  
\} catch(e) \{  
alert("不允许ActiveX控件"+e);  
\}  
alert(left+":"+bottom+":"+top+":"+right);  
\}  
  
  
//设置网页打印的页眉页脚和页边距  
function PageSetup\_Null() \{  
try \{  
var Wsh = new ActiveXObject("WScript.Shell");  
HKEY\_Key = "header";  
//设置页眉（为空）  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, "");  
HKEY\_Key = "footer";  
//设置页脚（为空）  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, "");  
HKEY\_Key = "margin\_bottom";  
//设置下页边距（0）  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, "0");  
HKEY\_Key = "margin\_left";  
//设置左页边距（0）

HKEY\_Key = "margin\_right";  
//设置右页边距（0）  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, "0");  
HKEY\_Key = "margin\_top";  
//设置上页边距（8）  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, "0.7");  
\} catch(e) \{  
alert("不允许ActiveX控件22"+e.message);  
\}  
\}  
  
  
//设置网页打印的页眉页脚和页边距为默认值  
function PageSetup\_Default() \{  
try \{  
var Wsh = new ActiveXObject("WScript.Shell");  
HKEY\_Key = "header";  
HKEY\_Key = "header";  
//还原页眉  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, head);  
HKEY\_Key = "footer";  
//还原页脚  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, foot);  
HKEY\_Key = "margin\_bottom";

HKEY\_Key = "margin\_left";

Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, left);  
HKEY\_Key = "margin\_right";  
//还原右页边距  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, right);  
HKEY\_Key = "margin\_top";  
//还原上页边距  
Wsh.RegWrite(HKEY\_Root + HKEY\_Path + HKEY\_Key, top);  
\} catch(e) \{  
alert("不允许ActiveX控件11");
