vue浏览器兼容打印 vue使用lodop打印控件实现浏览器兼容打印的方法
Allen-沐风 人气:0想了解vue使用lodop打印控件实现浏览器兼容打印的方法的相关内容吗，Allen-沐风在本文为您仔细讲解vue浏览器兼容打印的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：vue浏览器兼容打印,vue,lodop打印控件，下面大家一起来学习吧。
前言
此控件直接进行打印底部会有水印，通过官网购买可以解决；
如不想购买，可先执行预览，弹出预览框进行打印；
需要用到的js文件和api文档附后，请注意查看。
首先需要在局部或全局引入LodopFuncs.js文件
import {getLodop} from '../../../components/js/LodopFuncs'
方法中调用
print(){
let LODOP = getLodop();
LODOP.PRINT_INITA(0,0,800,1600,"打印库位名称");
LODOP.SET_PRINT_PAGESIZE(1,700,500,"") //设定纸张大小
LODOP.NewPage();//初始化
LODOP.SET_PRINT_MODE("RESELECT_PRINTER",true);
LODOP.ADD_PRINT_TEXT('10mm','50mm','30mm','20mm','iphone20Plus');//打印文字
LODOP.SET_PRINT_STYLEA(0,"FontSize",30);//字体样式
LODOP.ADD_PRINT_LINE('10mm','35mm','40mm','35mm',0,1);//打印直线
LODOP.ADD_PRINT_BARCODE('10mm','2.5mm','35mm','35mm',"QRCode",'123456');//打印二维码
LODOP.SET_PRINT_STYLEA(0,"AlignJustify",2);//二维码样式和规则
LODOP.SET_PRINTER_INDEXA("TSC TTP-244 Pro");//选择打印机
// LODOP.PRINT_DESIGN()//打开设置
// LODOP.PREVIEW(); //预览
LODOP.PRINT() //直接打印
},
LodopFuncs.js文件
//==本JS是加载Lodop插件及CLodop服务的综合示例，可直接使用，建议看懂后融进自己页面程序==
var CreatedOKLodopObject, CLodopIsLocal, CLodopJsState;
//==判断是否需要CLodop(那些不支持插件的浏览器):==
export function needCLodop() {
try {
var ua = navigator.userAgent;
if (ua.match(/Windows\sPhone/i))

if (verChrome[0] >= 41)
return true;
}
}
return false;
} catch (err) {

//==引用CLodop的主JS,用双端口8000和18000(以防其中一个被占):==
