I would like to use this lib on my typescript project. Sadly, types are not exported.
And when i try to import from:

import ThermalPrinter, { PrinterTypes } from 'browser-thermal-printer/src/core';

My typescript fails because my project has stricter rules.

Error: node_modules/browser-thermal-printer/src/interfaces/epson/epson.ts:251:30 - error TS2769: No overload matches this call.
The last overload gave the following error.
Type 'string | undefined' is not assignable to type 'string'.
Type 'undefined' is not assignable to type 'string'.
Type 'number' is not assignable to type 'string'.
251 this.append(Buffer.from([type, data.length]));

Is there away to export the.d.ts files two please.

Hello,
I am developing an app and I am trying to find a way to print labels directly from browser (especially mobile devices).
I found this library but browsing the code I didn't found where you tell some kind of detail about the printer. How can the library know to which printer to connect?

How to config interface using tcp, local or selecting printer?

Hi @Klemen1337 thanks for this module.

I have a question on how to ultimately send the commands to the printer.
From the code I see that you accumulate a Buffer with all the commands but how do you connect to the printer and send the buffer from the browser?

I see the Tested printers section in the README. Can you provide an example on what you're using to send the buffer commands to the printer?

Hello!

I was trying to implement this library in reactjs and I cannot get It working, do you have any example using reactjs?

import ThermalPrinter, { PrinterTypes, TableAlign } from "../src/core"

async function printTest() {

  const printer = new ThermalPrinter();
  printer.print("Hello World"); // Append text
  printer.println("Hello World"); // Append text with new line
}

module.exports = {
  printTest: printTest
};

I know that doesn't work because '../src/core' but if I try with

const ThermalPrinter = require('browser-thermal-printer');

It doesn't works. I got this error: TypeError: ThermalPrinter is not a constructor

Any help?
