WUP-MY-POS-PRINTER

开发文档

UTS 语法 UTS API插件 UTS 组件插件 Hello UTS

插件使用说明

简介

  1. 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。
  2. 适用于旻佑的各型支持票据打印的热敏打印机。
  3. 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。
  4. 使用本插件需要在Android 5.0以上设备使用。
  5. 插件支持uniapp的vue2 和 vue3 版本;uniapp x没做支持,可自行测试。
  6. 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";

插件测试方法

sayHi("wup-my-pos-printer", function (res) {
    console.log("sayHi", res)
})

枚举本地USB打印设备

enumUsb((res) => {
    console.log("enumUsb", res)
})

打开USB设备

    })

全切纸

打印时推荐使用posFeedAndHalfCutPaper,不推荐打印后再单独调用,可能出现切纸位置不准确问题。

fullCutPaper((res) => {
    console.log("fullCutPaper", res)
})

半切纸

打印时推荐使用posFeedAndHalfCutPaper,不推荐打印后再单独调用,可能出现切纸位置不准确问题。
