LODOP整页缩放，宽度、高度溢出缩放

LODOP中，超文本超过打印项高度会自动分页，可以用语句进行缩放，让打印内容都在一页中。
例如，整页缩放和高度溢出缩放。
如下是三个语句及其效果，注意对内容缩放可能会导致变形哦，毕竟是不等比例缩放：
LODOP.SET_PRINT_MODE("PRINT_PAGE_PERCENT","Full-Page");//整页缩放
效果：宽高都会缩放，缩放到整页里面。
LODOP.SET_PRINT_MODE("FULL_WIDTH_FOR_OVERFLOW",true);//宽度溢出缩放
效果：宽度超过纸张，把宽度缩放到合适到纸张里，高度超过纸张，高度不会缩放。
LODOP.SET_PRINT_MODE("FULL_HEIGHT_FOR_OVERFLOW",true);//高度溢出缩放
效果：高度超过纸张，把高度缩放到适合纸张的高度，宽度超过纸张不会缩放。
测试代码：

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>WEB打印控件LODOP</title>
<script language="javascript" src="LodopFuncs.js"></script>
</head>
<body>
<a href="javascript:prn1_preview()">打印预览</a><br>
<a href="javascript:prn2_preview()">打印预览整页缩放</a><br>
<a href="javascript:prn3_preview()">打印预览宽度溢出缩放</a><br>
<a href="javascript:prn4_preview()">打印预览高度溢出缩放</a><br>
<script language="javascript" type="text/javascript">   
        var LODOP; //声明为全局变量 
    function prn1_preview() {
        LODOP=getLodop(); 
        LODOP.PRINT_INIT("");
        LODOP.ADD_PRINT_LINE("34.4mm","82.81mm","34.1mm","101.31mm",0,1);
        LODOP.ADD_PRINT_URL(0,0,"100%","100%","http://www.c-lodop.com/index.html");    
        LODOP.PRINT_DESIGN();
        //LODOP.PREVIEW();    
    };
    function prn2_preview() {
        LODOP=getLodop(); 
        LODOP.PRINT_INIT("");
        LODOP.ADD_PRINT_URL(0,0,"100%","100%","http://www.c-lodop.com/index.html");    
        LODOP.SET_PRINT_MODE("PRINT_PAGE_PERCENT","Full-Page");
        LODOP.PRINT_DESIGN();
        //LODOP.PREVIEW();

    function prn3_preview() {
        LODOP=getLodop(); 
        LODOP.PRINT_INIT("");
        LODOP.ADD_PRINT_URL(0,0,"100%","100%","http://www.c-lodop.com/index.html");    
        LODOP.SET_PRINT_MODE("FULL_WIDTH_FOR_OVERFLOW",true);
        LODOP.PRINT_DESIGN();
        //LODOP.PREVIEW();

    function prn4_preview() {
        LODOP=getLodop(); 
        LODOP.PRINT_INIT("");
        LODOP.ADD_PRINT_URL(0,0,"100%","100%","http://www.c-lodop.com/index.html");

        LODOP.PRINT_DESIGN();
        //LODOP.PREVIEW();    
    };
        
</script>
