Plick Electron pos printer

A customizable electron.js printing plugin specifically designed for thermal receipt printers. It supports 80mm, 78mm, 76mm, 58mm, 57mm, 44mm printers.

When recommend to use the 24.8.8 electron version, any major version of electron could not work properly

Installation

$ npm install @plick/electron-pos-printer

Usage

When using it on Electron require import is mandatory even if you are using typescript

const { PosPrinter } = require('@plick/electron-pos-printer');

Outside Electron and on a TS environment we can use import

import { PosPrinter } from '@plick/electron-pos-printer';

Otherwise, on JS environments we can use require

const { PosPrinter } = require('@plick/electron-pos-printer');

Typescript

import { PosPrinter, PosPrintData, PosPrintOptions } from '@plick/electron-pos-printer';

const options: PosPrintOptions = {
  preview: false,
  margin: '0 0 0 0',
  copies: 1,
  printerName: 'XP-80C',
  timeOutPerLine: 400,
  pageSize: '80mm', // page size
};

const data: PosPrintData[] = [
  {
    type: 'image',
    url: 'https://randomuser.me/api/portraits/men/43.jpg', // Can be a URL or change the key to "path" if you want to use a local file on disk

FAQ

Having sizing issues? Try to set the pageSize option to:

pageSize: {
  width: 71000,
  height: 301000,
}

For previews only, you can set the width to 205 (close to 80mm size):

pageSize: {
  width: 205,
  height: 301000,
}

Having table issues? This fields are mandatory on tables, you can leave them empty but they must be present:

tableHeader
tableBody
tableFooter
tableHeaderStyle
tableBodyStyle
tableFooterStyle
