WUP-MY-POS-PRINTER 旻佑热敏打印机票据打印uniapp插件使用说明

插件地址：WUP-MY-POS-PRINTER 旻佑热敏打印机票据打印安卓库

简介

本插件主要用于旻佑热敏打印机打印票据，不支持标签打印。
适用于旻佑的各型支持票据打印的热敏打印机。
本插件开发时使用的打印机型号为MY-805嵌入式面板打印机，其他型号请先试用测试。
使用本插件需要在Android 5.0以上设备使用。
插件支持uniapp的vue2 和 vue3 版本；uniapp x没做支持，可自行测试。
初始化流程：获取设备-打开设备-设置多字节模式及编码。

方法

方法引入

import { sayHi, 需引入的其他方法 } from "@/uni_modules/WUP-MY-POS-PRINTER";
