vue使用lodop打印控件实现浏览器兼容打印的方法

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
