HTML中使用Lodop打印

我们在项目中，会需要用到连接打印机进行打印订单数据信息等，本次我使用的是 Lodop 进行打印

• 我们会用到 Lodop 的依赖文件

1、安装软件
CLodop_Setup_for_Win32NT.exe
2、32版本的运行文件
install_lodop32.exe
3、64版本的运行文件
install_lodop64.exe
4、JS文件
LodopFuncs.js

以上文件已经放在百度网盘：

提取码：vpod

• 一、根据项目实际情况，将 LodopFuncs.js 文件中的路径修改正确

文件第62行，function getLodop(oOBJECT, oEMBED) {}，方法里面的每个 href 改为你项目中正确的路径，供用户打印时下载安装

• 二、提供打印按钮

<button class="btn_own btn_toolbar btn-purple no-border" href="#" id="btn_print" onclick="printOwn()" style="border-width: 0;">
    <i class="glyphicon glyphicon glyphicon-print blue" class="btn_icon"></i>打印
</button>

• 三、执行打印
• 3-1、引入 LodopFuncs.js

<!-- lodop打印 -->
<script src="<%=path%>/js/lodop/LodopFuncs.js"></script>

• 3-2、定义打印对象

var lodopObj;

• 3-3、加载打印设备

// 加载打印插件
function initPrint() {
    var flag = true;
    if(null == lodopObj ) {
        flag = false;
        var loading = layer.msg('正在初始化打印机...', {
            icon: 16,
            shade: [0.1,'#000'],
            time:200000
        });
        // 防止LODOP 对象加载未完成
        setTimeout(function (args) {
            // 获取LODOP
            lodopObj = getLodop();
            layer.close(loading);
            if((!lodopObj) || (!lodopObj.VERSION)){
                // Lodop插件未安装时
                // layer.closeAll();
            }else {
                layer.msg('打印机加载完成，请等待打印', {icon: 1, time: 2000});
                printOwn();
            }
        }, 1000);
    }
    return flag;
}

• 3-4、打印按钮的点击事件

function printOwn() {
    // 优先加载打印机
    if(initPrint()) {
        // 根据查询需要打印的数据
        $.ajax({
            url : '<%=path%>/distribute/listOutDistributeDtailForPrint.action',
            type : 'post',
            dataTpe : 'json',
            data : {
                "orderId" : row.outNumber
            },
            success : function (data) {
                // 执行打印
                toPrint(data, row.outNumber, row.outDate, row.busiUserName, row.storeName, row.storeInName);
            },
            error: function (data) {
                layer.msg('打印异常！');
            }
        })
    }
}

• 3-5、执行打印

// 执行打印
function toPrint(details, orderId, busiDate, busiUserName, outStoreName, inStoreName) {
    var resHtml = '<style> table,td,th {border: 1px solid black;border-style: solid;border-collapse: collapse;}table{width:100%;font-size:14px}</style><table border="1">';
    resHtml += '<tr>';
    resHtml += '<td width="5%">序号</td>';
    resHtml += '<td width="40%">商品名称</td>';
    resHtml += '<td width="45%">序列号</td>';
    resHtml += '<td width="10%">分拨数量</td>';
    resHtml += '</tr>';
    // 数量合计
    var quantityAll = 0;
    var detail = JSON.parse(details);
    for(var i =0, len = detail.length; i < len; i++) {
        resHtml += '<tr>';
        resHtml += '<td style="text-align: center">'+(i+1)+'</td>';
        if(1 == detail[i].isDemonstrator){
            resHtml += '<td>'+detail[i].skuName+'(演示机)</td>';
        }else{
            resHtml += '<td>'+detail[i].skuName+'</td>';
        }
        resHtml += '<td>'+detail[i].serialNumber+'</td>';
        resHtml += '<td style="text-align: center">'+detail[i].quantity+'</td>';
        resHtml += '</tr>';
        quantityAll += parseInt(detail[i].quantity);
    }
    resHtml += '<tr>';
    resHtml += '<td colspan="2" style="text-align: center">合计</td>';
    resHtml += '<td></td>';
    resHtml += '<td style="text-align: center">'+quantityAll+'</td>';
    resHtml += '<td></td>';
    resHtml += '</tr>';
    resHtml += '</table>';
    // 表格上头的数据
    var rHead = '<style> .htable,td,th {border: none;border-style: solid;border-collapse: collapse;}.htable{width:100%;font-size:15px}</style>';
    rHead += '<table border="0">';
    rHead += '<tr>';
    rHead += '<td width="15%">单据编号:</td>';
    rHead += '<td width="15%">'+orderId+'</td>';
    rHead += '<td width="15%">单据日期:</td>';
    rHead += '<td width="25%">'+busiDate+'</td>';
    rHead += '<td width="15%">经手人:</td>';
    rHead += '<td width="15%">'+busiUserName+'</td>';
    rHead += '</tr>';
    rHead += '<tr>';
    rHead += '<td>调出仓库:</td>';
    rHead += '<td>'+outStoreName+'</td>';
    rHead += '<td>调入仓库:</td>';
    rHead += '<td>'+inStoreName+'</td>';
    rHead += '<td></td>';
    rHead += '<td></td>';
    rHead += '</tr>';
    rHead += '</table>';
    lodopObj.PRINT_INITA(0,0,1200,600,"");
    lodopObj.SET_PRINT_MODE("PRINT_NOCOLLATE",1);
    lodopObj.ADD_PRINT_TABLE(10,15,"197.88mm",446, rHead);
    lodopObj.ADD_PRINT_TABLE(90,15,"197.88mm",446, resHtml);
    // 执行打印预览
    lodopObj.PREVIEW();
}

• 3-6、后端查询数据

@RequestMapping(value = "listAllocationOrderDetails")
@ResponseBody
public String listAllocationOrderDetails(String orderId) {
    List<AllocationOrderDetail> list = allocationOrderService.listAllocationOrderDetailByOrderId(orderId);
    return JSONArray.toJSONString(list);
}

• 四、打印预览
