I think the issue is being caused by the utils.inherit() which is deprecated. I fixed this by copying all the code in the escpos-usb module into a file, commenting out that part, then requiring that file instead.

this is because escpos-usb has a wildcard dependency on usb, which means it's pulling in versions with breaking changes it's not compatible with. with recent versions of npm you can fix this by adding a version override for usb to your package.json:

  "overrides": {
    "usb": "1.8.8"
  }

you can try : usb.usb.on ...

Was the same problem. @apaleslimghost solution helps.
