首先在网页中添加： <OBJECT id="WebBrowser" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" VIEWASTEXT> </OBJECT> 然后就可以依次加入功能按钮了： <input onclick="document.all.WebBrowser.ExecWB(6,1)" type="button" value="打印"> <input onclick="document.all.WebBrowser.ExecWB(6,6)" type="button" value="直接打印"> <input onclick="document.all.WebBrowser.ExecWB(8,1)" type="button" value="页面设置"> <input onclick="document.all.WebBrowser.ExecWB(7,1)" type="button" value="打印预览"> <INPUT type="button" value="关闭窗口" onclick="javascript:window.close()"> 将这两块东西放到<center class=noprint></center>就不会打印这些按钮了。当然要定义noprint了： <style media="print">.Noprint { DISPLAY: none }</style>只要把不想打印的东西的css设置成noprint就可以了。 现在就实现了基本的web打印，需要注意的情况如下： 必须将ie的internet选项的安全设置中对于没有标记为安全的ActiveX控件进行
设置成提示或者启用，否则会报错，导致不可用。 如果在vs.net编辑环境下编辑该页面，它经常自动的给object添加多余的参数，有了这些东西，打印就会出错，所以要记得最后保存的时候删除它们。 为了简便并且达到最好的效果，我们可以在一个页面实现编辑和打印，这时候会需要很多的textbox，我们把它的css设置成.edittext { overflow-y:visible; 100%; border-top: none; border-right: none; border-bottom: none; border-left: none; }就可以实现在打印的时候不显示边框和multiline的textbox不显示滚动条了。 还有一些小经验就是在设置标格宽度的时候，对于A4纸张，横打用920，竖打用640，效果最好。 1、控制"纵打"、 横打”和“页面的边距。 （1）<script defer>
