<script>
newwin=window.open("","","");
newwin.document.write("<style>");
newwin.document.write("@media print {");
newwin.document.write(" .ptn {display:block;} ");
newwin.document.write(" .notptn {display:none;}");
newwin.document.write("}");
newwin.document.write("</style>");
newwin.document.write("<div class='ptn'>要打印的内容</div>");
newwin.document.write("<div class='notptn'><input type=button value=print onclick='window.print()'></div>");
</script>
