1．首先引入一个WebBrowser在需要打印的页面，可以直接添加：
复制代码 代码如下:
<object id="WebBrowser" classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 height="0" width="0">
</object>
到页面，或者使用JavaScript在需要的时候临时添加也可以：
复制代码 代码如下:
document.body.insertAdjacentHTML("beforeEnd",
"<object id=\"WebBrowser\" width=0 height=0 \
classid=\"clsid:8856F961-340A-11D0-A96B-00C04FD705A2\">");
2 .页面设置和打印预览
如下所示，直接调用即可
复制代码 代码如下:
document.all.WebBrowser.ExecWB(6,6) 直接打印
document.all.WebBrowser.ExecWB(8,1) 页面设置
document.all.WebBrowser.ExecWB(7,1) 打印预览
或者：
复制代码 代码如下:
execScript("document.all.WebBrowser.ExecWB 7, 1","VBScript");
3 隐藏不打印的页面元素和分页
CSS 有个Media 属性，可以分开设置打印和显示的格式。
如 <style media="print" type="text/css"> …</style> 中间的格式将只在打印时起作用，不会影响显示界面。
所以可以设定
<style media="print" type="text/css">
.Noprint{display:none;}
.PageNext{page-break-after: always;}
</style>
然后给不想打印的页面元素添加： class="Noprint" ，那就不会出现在打印和打印预览中了。
想分页的地方添加： <div class="PageNext"></div> 就可以了。
4．打印页面的特定部分
通过将需要打印的特定部分另建一个页面，然后装入主页面的一个IFrame中，再调用IFrame的打印方法，只打印IFrame中的内容实现的。
如：
<iframe style="visibility: visible" name="FrameId" width="100%" height="30%" src="/UploadFiles/2021-04-02/NeedPrintedPage.asp">下面的pringFrame js函数将只打印Iframe中的内容，可以直接引用使用,如printFrame(FrameId);
复制代码 代码如下:
window.print = printFrame;
// main stuff
function printFrame(frame, onfinish) {
if ( !frame ) frame = window;
function execOnFinish() {
switch ( typeof(onfinish) ) {
case "string": execScript(onfinish); break;
case "function": onfinish();
}
if ( focused && !focused.disabled ) focused.focus();
}
if (( frame.document.readyState !== "complete") &&( !frame.document.confirm("The document to print is not downloaded yet! Continue with printing?") ))
{
execOnFinish();
return;
}
var eventScope = printGetEventScope(frame);
var focused = document.activeElement;
window.printHelper = function() {
execScript("on error resume next: printWB.ExecWB 6, 1", "VBScript");
printFireEvent(frame, eventScope, "onafterprint");
printWB.outerHTML = "";
execOnFinish();
window.printHelper = null;
}
document.body.insertAdjacentHTML("beforeEnd",
"<object id=\"printWB\" width=0 height=0 \
classid=\"clsid:8856F961-340A-11D0-A96B-00C04FD705A2\">");
printFireEvent(frame, eventScope, "onbeforeprint");
frame.focus();
window.printHelper = printHelper;
setTimeout("window.printHelper()", 0);
}
// helpers
function printIsNativeSupport() {
var agent = window.navigator.userAgent;
var i = agent.indexOf("MSIE ")+5;
return parseInt(agent.substr(i)) >= 5 && agent.indexOf("5.0b1") < 0;
}
function printFireEvent(frame, obj, name) {
var handler = obj[name];
switch ( typeof(handler) ) {
case "string": frame.execScript(handler); break;
case "function": handler();
}
}
function printGetEventScope(frame) {
var frameset = frame.document.all.tags("FRAMESET");
if ( frameset.length ) return frameset[0];
return frame.document.body;
}
Iframe中所装载页面的打印效果在所装载页面设置就可以了，如分页等。
5．后台打印
通过建一个隐藏Iframe实现的，当然仍然会有页面装载的过程。
下面的函数创建Iframe装载页面并打印。如 printHidden(url) //url为页面地址
function printHidden(url) {
document.body.insertAdjacentHTML("beforeEnd",
"<iframe name=printHiddenFrame width=0 height=0></iframe>");
var doc = printHiddenFrame.document;
doc.open();
doc.write("<body onload=\"parent.onprintHiddenFrame()\">");
doc.write("<iframe name=printMe width=0 height=0 src=\"" +
url + "\"></iframe>");
doc.write("</body>");
doc.close();
}
function onprintHiddenFrame() {
function onfinish() {
printHiddenFrame.outerHTML = "";
if ( window.onprintcomplete ) window.onprintcomplete();
}
printFrame(printHiddenFrame.printMe, onfinish);
}
它用到了printFrame，所以别忘了引用前面的函数。
以下为demo:
<html>
<head>
<title>报表</title>
<object id="WebBrowser"
classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 height="0"

function onfinish() {
printHiddenFrame.outerHTML = "";
if ( window.onprintcomplete ) window.onprintcomplete();
}
printFrame(printHiddenFrame.printMe, onfinish);

</script>
