Hello. I have the same problem, but can't fix it... now i test with this package https://www.npmjs.com/package/escpos but return me another problem. One of the recommended solutions is to use Electron 12, I currently have version 13, I will be trying to downgrade to version 12 and try again... I am working on a project with:

VueJS, Express and Electron

node version 16.20 and npm version 8.19.4

I found a solution and this is working for me now, but using another package for VueJS and Electron, this is the package https://www.npmjs.com/package/electron-pos-printer-vue/v/1.0.9 if you are using something like Vuejs and Electron i share my code example here:

  <button @click="imprimir">Imprimir</button>
  <HelloWorld msg="Welcome to Your Vue.js App" />
</template>

<script>
import HelloWorld from './components/HelloWorld.vue'
const { PosPrinter } = require('electron').remote.require("electron-pos-printer-vue");
//const path = require("path");

export default {
  name: 'App',
  components: {
    HelloWorld
  },
  methods: {
    async imprimir() {
      const options = {
        preview: false,               // Preview in window or print
        width: '170px',               //  width of content body
        margin: '0 0 0 0',            // margin of content body
        copies: 1,                    // Number of copies to print
        printerName: 'ImpresoraBarata',        // printerName: string, check with webContent.getPrinters()
        //printerName: 'EPSON TM-T88V Receipt',        // printerName: string, check with webContent.getPrinters()
        timeOutPerLine: 400,
        pageSize: { height: 301000, width: 71000 },  // page size
        silent: true
      }

      const data = [
         {
          type: 'text',                                       // 'text' | 'barCode' | 'qrCode' | 'image' | 'table

Ran into the same error. I inspected the node_modules/electron-pos-printer and it didn't have all the required files. Downgraded to 1.3.6 and it works just fine.
