js打印（控件）及多种方式

非常好用的LODOP打印控件

Lodop打印控件简单使用方法
1.安装。

2.调用LodopFuncs.js文件。

3.增加OBJECT对象

<script language="javascript" src="LodopFuncs.js"></script>

<object id="LODOP" classid="clsid:2105C259-1E0C-4534-8141-A753534CB4CA" width=0 height=0>

<embed id="LODOP_EM" type="application/x-print-lodop" width=0 height=0></embed>

</object>

4.获取

<script language="javascript">

var LODOP=getLodop(document.getElementById('LODOP'),document.getElementById('LODOP_EM'));

</script>

5.调用函数

LODOP.函数名

（1）打印初始化（PRINT_INIT）

（2）设定纸张大小（SET_PRINT_PAGESIZE）

（3）增加打印项

---ADD_PRINT_HTM-增加超文本打印项(普通模式)

---ADD_PRINT_TABLE-增加表格打印项（超文本模式）

---ADD_PRINT_TEXT-增加纯文本打印项

---ADD_PRINT_IMAGE-增加图片打印项

---ADD_PRINT_BARCODE-增加条形码

（4）设置打印项风格（SET_PRINT_STYLEA）

（5）强制分页（NEWPAGEA）

（6）打印

---PREVIEW-打印预览

---PRINT-直接打印

---PRINT_SETUP-打印维护-目标使用者是最终用户

---PRINT_DESIGN-目标使用者是软件开发者

附：计量单位

本文所述px单位固定换算关系如下,与像素类似但不是一个概念，也不受显示影响：

1in(英寸)=2.54cm(厘米)=25.4mm(毫米)=72pt(磅)=96px

另外一个特殊的计量单位“%(百分比)”，是指相对于纸张大小的百分比值，其中“上、下边距、高度”等的百分比是相当对于纸张高度（横向打印时则是宽度）的比值，而“左、右边距和宽度”的百分比是相对于纸张宽度（横向打印时则是高度）的比值。

提示：打印预览时，虚线之外是物理不可打区域，不同的打印机其物理边距不一样

-------------------------------------------------------------------------------

边距：LODOP控件设置边距

每个打印项上边距、左边距，及纸张的宽度。

例：要设置左右边距为5px,可设置

LODOP.SET_PRINT_PAGESIZE(1, “200px”, “800px”, “”);

LODOP.ADD_PRINT_TABLE(“0”,”5px”,”190px”,””,document.getElementById(“my_tab”));//左右边距都为5px;

-------------------------------------------------------------------------------

打印宽度确定，长度不确定：

LODOP.SET_PRINT_PAGESIZE(3,”260px”,”10px”,””);

var table_height= document.getElementById(“my_tab”))..offsetheight();

LODOP.ADD_PRINT_TABLE(“0”,”5px”,”190px”, table_height,document.getElementById(“my_tab”).innerHTML);

-------------------------------------------------------------------------------

首先需要下载、引用JS 脚本
