In the long run, we should migrate the callbacks to promises

USB constructor using the printer you pass to it.

When passing the vid and the pid to USB constructor is printing in the latest connected printer.

[RFC] Printing by HTML+CSS.

The different printers have a lot of other instruction sets. But most printer has implemented the BMP instruction. So it will be more accessible and customized if we modify the printing content by HTML+CSS.

Add types for @node-escpos/serialport-adapter.

如何使用這個版本

你好：想請問如何使用你優化後的escpos？要如何安裝？

Error: Port is opening (Linux and Windows)

Hi! I'm trying to use a thermal printer Dascom DT-230 with the serialport adapter. Now the printer is connected to my PC using usb but the pc detects that as a serial port

In Windows as COM4
In Linux as /dev/ttyACM0

In both cases that return Error: Port is opening

It's the code that I was testing

import { Printer } from "@node-escpos/core";
import Serial from "@node-escpos/serialport-adapter";

const device = new Serial("/dev/ttyACM0", { // In Windows I was put "COM4"
  baudRate: 115200,
  stopBit: 1,
});

const options = {
  encoding: "utf-8",
};

const printer = new Printer(device, options);

device.open((error) => {
  if (error) {
    console.error(error);
    return;
  }

  let printer = new Printer(device, {});

  printer
    .font("a")
    .align("ct")
    .style("bu")
    .size(1, 1)
    .text("The quick brown fox jumps over the lazy dog");

  printer.cut().close();
});

Someone can help me with that? I have been trying different packages to use escpos printers for months and I have not found any that give me results

Table items are not aligned

When I print the below code, the row items are not aligned to center with the column

How to install and run this module?

i have installed this module using npm i @node-escpos/core and npm i @node-escpos/usb-adapter
and try using sample script

import { Printer, Image } from "@node-escpos/core";
// install escpos-usb adapter module manually
import USB from "@node-escpos/usb-adapter";
// Select the adapter based on your printer type
import { join } from "path";

const device = new USB();

device.open(async function(err){
  if(err){
    // handle error
    return
  }

  // encoding is optional
  const options = { encoding: "GB18030" /* default */ }
  let printer = new Printer(device, options);

  // Path to png image
  const filePath = join("/PATH/TO/IMAGE");
  const image = await Image.load(filePath);

  printer
    .font("a")
    .align("ct")
    .style("bu")
    .size(1, 1)
    .text("May the gold fill your pocket")
    .text("恭喜发财")
    .barcode(112233445566, "EAN13", { width: 50, height: 50 })
    .table(["One", "Two", "Three"])
    .tableCustom(
      [
        { text: "Left", align: "LEFT", width: 0.33, style: "B" },
        { text: "Center", align: "CENTER", width: 0.33 },
        { text: "Right", align: "RIGHT", width: 0.33 },
      ],
      { encoding: "cp857", size: [1, 1] }, // Optional
    )
    
  // inject qrimage to printer
  printer = await printer.qrimage("https://github.com/node-escpos/driver")
  // inject image to printer
  printer = await printer.image(
    image, 
    "s8" // changing with image
  )

  printer
    .cut()
    .close()
});

Hello, according to your method, I tried to write and print, but when I wrote the background, there was a branch when printing. How can I solve the problem of incomplete printing caused by the branch?

[FEATURE REQUEST] Implement bluetooth-adapter.

Currently, I don't have any Bluetooth printer to test, so I can't implement this adapter. If you have a Bluetooth printer and want to help, welcome PR.

BTW, maybe nouble is a good choice for this part.

Cannot change Barcode spacing between lines with Barcode Options

Unlike @escpos Parent Repository. i cannot set witdh and height barcode in paper 80 mm
if is a long number the barcode is long.

I hope the barcode scales left and right if the data number is short;

printer.text('The quick brown fox jumps over the lazy dog')
        .barcode(65656556565,"CODE39", {
                    width : 50,
                    height : 50,
        })
         .cut()
         .close()

Spacing between Barcode Rows functions so that the barcode can be seen clearly when scanned

The original library song940/node-escpos works, but this library gives me this error. I have been at this for two days. Can't seem to figure out why.

Can't use printer.getStatus

As of version 0.4.0 of @node-escpos/core, I can´t find a way to actually use printer.getStatus due to the fact that the status classes are not exported.

Please maintain This Repo. Update NPM Code

Please Update This Pull Request #80 (comment) to NPM. i need this update

Don't Work with Metapace T-40

Metapace can understand ESC/POS but I cloud not change barcode width. Barcode is very small. Also QR code is not printed, only the value as text.
Are there any tricks to correct this?

Thanks for hints.

Error importing in common js

Hi, this is a great library. However, Im having a bit of a problem when importing this to my recent project (common js) which uses https://github.com/song940/node-escpos.

So my current implementation of node-escpos uses an import like this

// my printer vendorId
const vendorId = '0x0483'

//my printer product id
const ProductId = '0x5743'

const escpos = require("escpos");
const device = new escpos.USB(vendorId, productId);
let printer = new escpos.Printer(device);


 if (device != null) {
   device.open(function () {
          printer
            .font("a")
            .align("ct")
            .style("bu")
            .size(1, 1)
            .text("Testing Printer")
            .text("The quick brown fox jumps over the lazy dog")
            .barcode("6611235132450000000000", "CODE93", {
              height: 35,
              width: 1,
            })
            .control("lf");
          printer.cut();
          printer.close();
   
   }
 }

Here is what I've tried so far on import

"use strict";

var _core = require("@node-escpos/core");
var _usbAdapter = _interopRequireDefault(require("@node-escpos/usb-adapter"));
function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { "default": obj }; }

here is the error message being rendered on the console

node_modules\@node-escpos\core\dist\index.mjs:1
(function (exports, require, module, __filename, __dirname, process, global, Buffer) { return function (exports, require, module, __filename, __dirname) { import EventEmitter from 'eventemitter3';

USB close function removes all usb detach listeners

The close function of the usb adapter removes all detach listeners from the USB event emitter when the close function of a printer is called. That's a really bad practice as all listeners are removed from the event even those which are created in other packages or libraries.

 close(callback?: ((error: Error | null) => void) | undefined): this {
    if (!this.device) callback?.(new Error("Device not found"));
    try {
      this.device?.close();
      usb.removeAllListeners("detach");

As i am also listening for the usb.on('detach') event my code gets broken after a device close() was called... The detach event is used to remove the active printer if its linked device is detached:

usb.on("detach", (device) => {
      if (device === self.device) {
        self.emit("detach", device);
        self.emit("disconnect", device);
        self.device = null;
      }
    });

Expected behaviour: Only the single listener from this library should be removed if the close function is called

Best practice question: Keep the printer connection open or not?

What is best practice? To keep the printer connection open all the time as long as the application is running / detached or to close the printer connection each time a print was finished?

I have just found an article from Zebra which indicates that the connection should be closed after each print as long as there are not multiple jobs to be printed in a short amount of time: https://techdocs.zebra.com/link-os/2-14/bestpractices/. Any suggestions?

In this library it would be possible for USB printers to close the connection, but that is not true for serialport printers as the device is thrown away after a close.

Use without WinUsb driver

Can we use this package without installing the WinUSB driver or there is a way to silently install the WinUSB driver through code?

I tried using usb.useUsbDkBackend() from the node-usb package but no luck as mentioned in the readme.md section of https://github.com/node-usb/node-usb

Primarily, I don't want the client to do an extra WinUSB installation.

Margin functions have no impact

The available functions printer.marginBottom(), printer.marginLeft(), printer.marginRight() have no impact on my printer using Epson TM-T20. I am a little bit confused as setting the margin is specified different:

Can anyone give me a hint what settings are applied when using the build-in functions from this library?

export const MARGINS = {
  BOTTOM: "\x1B\x4F", // Fix bottom size
  LEFT: "\x1B\x6C", // Fix left size
  RIGHT: "\x1B\x51", // Fix right size
};

usage getStatus and getStatuses functions

I want to use getStatus function and when I call it as follows,
PrinterStatus and other classes not exported.
So, let printerStatus = printer.getStatus(PrinterStatus); // class type can't work

this exports can be added

or
let printerStatus = printer.getStatus("PrinterStatus"); // string type can't work
this code can be added

Or is there any other solution besides these ? How should I use getStatus() function ?

Help me use bluetooth adapter

What are the prerequisites for bluetooth interface connection?

I have been able to successfully setup usb-adapter interface.

But having trouble with bluetooth-adapter as my Epsom TM m30 doesn't show up.

Can someone please guide on how to make this work with bluetooth connection.

Unable to load an image with a callback function

First of all, thanks for the great work.
I am trying to migrate from escpos and escpos-usb to your driver.
I tried a simple test
async function test() { try { const image = await Image.load('./assets/Packback-black.png'); console.log(image); } catch (error) { console.error('Error loading image:', error); } }

And this successfully loads my image.

Then I tried with a callback function, but this doesn't work :
function test(callback) { Image.load('./assets/Packback-black.png', (err, image) => { if (err) { // Handle error console.error('Error loading image:', err); return; } // Image loaded successfully, call the callback function callback(image); }); }

I get the following error
`C:\Users\thoma\Documents\Computer Projects\LTNG-state-machine\xstate\node_modules\get-pixels\node-pixels.js:126
cb(new Error("Unsupported file type: " + mimeType))
^

Error: Unsupported file type: (err, image) => {
if (err) {
// Handle error
console.error('Error loading image:', err);
return;
}
// Image loaded successfully, call the callback function
callback(image);
}
at doParse (C:\Users\thoma\Documents\Computer Projects\LTNG-state-machine\xstate\node_modules\get-pixels\node-pixels.js:126:10)
at C:\Users\thoma\Documents\Computer Projects\LTNG-state-machine\xstate\node_modules\get-pixels\node-pixels.js:190:7
at FSReqCallback.readFileAfterClose [as oncomplete] (node:internal/fs/read/context:68:3)
`

Like the callback function is interpreted as the "type" parameter of the load function.
But I also tried to add a type but then nothing happens since I don't read the image output.

Any idea what might be the issue ? Do I use the new version wrong ?

Thanks for the help !
