C#打印小票（连续自动打印）

#自动打印小票

方法一（后端生产打印代码）

注意前端需要引用（LodopFuncs.js,JsBarcode.all.min.js,jquery.js）当然还有安装打印机驱动还有Lodop的驱动
前端代码调用打印方法部分
json.printinfo是后端传向前端的生成好的打印代码。

  //执行打印小票var orderids = "";if (json.printinfo != ""){var imgsrc = "\"../../../Content/img/wjywx.jpg\"";function print() {if (needCLodop()) { loadCLodop(); }window.On_CLodop_Opened = function () {eval(atou(json.printinfo)); //OpenPreview()是调用打印方法                        window.On_CLodop_Opened = null;};  if ("undefined" != typeof CLodopMessage) {layer.msg(CLodopMessage, {time: 20000, //20s后自动关闭btn: ['前往下载'],id: 'layerDemo',yes: function () {window.open('../../Upload/驱动/CLodop_Setup_for_Win32NT.exe')}});} //打印小票完成根据订单id去修改订单在数据库中的状态if (orderids != "") {$.ajax({type: 'POST',url: "../Home/UpdateOrderStatic?Orderid=" + orderids,data: "",dataType: 'json',async: false,cache: false,success: function (json) {if (json.responseText == "True") {alert("打印完成")} else {alert("修改订单状态失败")}}})}}print();}

LODOP = getLodop();
LODOP.PRINT_INIT('');
var ele = document.createElement("img");
JsBarcode(ele, thisorderid, {displayValue: true,

});var srcdata = ele.src;
srcdata = srcdata.replace(/\+/g, "%2B");
srcdata = srcdata.replace(/\&/g, "%26");//生成订单二维码,临时保存到缓存内

//截取新订单id
LODOP.ADD_PRINT_URL(0, 0, "100%", "100%", "" + url + "?orderIds=" + thisorderid + "&IsAutoPrint=1");
