Everything is fine until I exceed 251 characters in the string for Qr.
Any ideas?
thanks,

My printer supports code128 and I'm using your package as it's very good and easy to use. but the package does not support code128.
could you please guide me to add code128 ?

Hello, I'm trying to print an image in my ionic app.
var img = new Image();
img.src = 'https://sguru.org/wp-content/uploads/2018/02/facebook-logo-jpg-facebook-logo-1.jpg';
.image(img, 40, 40, 'threshold')
This is part of the code, but when I try to print there isn't any image on the receipt, it's all blank and in the ispection there aren't any errors. Can you give me support on this problem? Thank you.

Is there a way to print Cyrillic text using this package? I tried to use many variants, but got question marks or unreadable text. Please help me with this issue.

not worked for me
let result = encoder.codepage('cp866').text('Привет мир')
let result = encoder.codepage('windows1251').text('Привет мир')

Even if the images are white background jpg, or transparent background png.

I am using the following.

.align('left').text('Left side').align('right').text('right side').newline()

But it aligns the whole text to the left.

Hi,
First of all, thanks very much for your package.
It is great!
I am trying to print an image via react-native, but I don't know how to define a suitable argument (img) for the image function in react-native.
.image(img, 300, 300, 'atkinson').
As far as I know, we can include images in react-native via one of the following codes:
would you be able to help me?
Thanks

Hi.
Thanks for the great plugin.
My print layout needs to print large text in addition to small and normal text.
I have been searching, but with no luck.
Something similar to the following image. Sorry for low res image.
Any help appreciated.

When I try to use your library, just calling new EscPosEncoder throws the error:

I'm using angular 11.

I have followed your documentation .. The error is (Image not defined) . Then i tried to load image using fs.readFile even though I unable to load image

I'm trying to print image and qrcode with our bluetooth device. But there're some problems.

Problems

• When printing image, it seems that the width and height must be limited to less than 64, or it will print part of the image or some codes or characters I can not read.
• When printing qrcode, it will print texts like 1A21C1E11P0https://nielsleenheer.com1Q0 instead of the qrcode image.

Printer & Codes

BTW, the printer I've used is Xprinter XP-Q200.
The printing data, which is in Base64 formation and is generated by a node script, is writen to printer with react-native-ble-plx which accept Base64 string.

Node script to get Base64 string for printing:

const EscPosEncoder = require('esc-pos-encoder');
const {loadImage} = require('canvas')

const encoder = new EscPosEncoder();

async function main() {
  const img = await loadImage('./seller_5.png')
  const result = encoder
    .initialize()
    .align('center')
    // image
    .image(img, 224, 64)
    // qrcode
    // .qrcode('https://nielsleenheer.com')
    .encode();

  console.log(Buffer.from(result).toString('base64'));
}

main()

The './seller_5.png' image:

core.js:6014 ERROR Error: Uncaught (in promise): ReferenceError: Cannot access 'HomePageModule' before initialization
ReferenceError: Cannot access 'HomePageModule' before initialization

but once I take off the import, app runs smoothly

I have a printer, if I send to much data, it prints incomplete.
If I send a url longer than 64 characters, then the qrcode it printed is not the same as the url I send, it ends with scrambled code.

For example,
https://order.keguanll.com/scan-order?orderId=169&twoDCId=19&authInfo=h_PFh-1V_rCzHUpYJqHvqmuCvf8%3D
becomes
https://order.keguanll.com/scan-order?orderId=169&twoDCId=19&auth�@�a� �(k�

It doesn't print correctlly either if I send data of an image.

How to resolve this problem, how to slice the result buffer, and send them individually?

The package is very similar with node-escpos but the advantage of this package is that you can use it directly to your Web App and print using a thermal printer with Web Bluetooth API, unlike the node-escpos it is not design to be used directly with your web app, unless you use express.js. But they have a complete set of features that can be use to your nodejs project like the table feature which is the one that was currently missing on this package.

Is there a way to achieve the output below? Or is there an upcoming updates in the future for this?

Instead of text, printer prints out the codepage name, like 'ascii' or 'cp850'.

Hello everyone.

I have been trying to print a receipt using this package to send the data to the printer, however when I try to print with an image it is not working properly, the printer stops at a certain point and does not keep printing. This is my code:

  var impresora = this.printerService;
  const encoder = new EscPosEncoder();
  let img = new Image();
  img.src = 'assets/imgs/colsaisa3.png';
  img.onload = function () {
    const encoder = new EscPosEncoder();
    let result = encoder
      .codepage('cp852')
      // .newline()
      .image(img, 120, 120, 'atkinson')
      .newline()
      .newline()
      .align('center')
      .line('Recibo de caja')
      .line(resp.id)
      .newline()
      .newline()
      .align('left')
      .line('CLIENTE: ' + resp.cliente)
      .line('IDEN: ' + resp.iden)
      .line('FECHA: ' + resp.fecha)
      .line('VENDEDOR: ' + resp.vendedor)
      .newline()
      .newline()

      .bold(false);
    for (const item of resp.facturas) {
      const cantFactura = (item.numeroFactura.toString().length <= 11) ? 11 - item.numeroFactura.toString().length : 0;
      const cantSaldo = (formatNumber(item.saldo, 'en-US').length <= 11) ? 11 - formatNumber(item.saldo, 'en-US').length : 0;
      const cantPago = (formatNumber(item.valorConsignar, 'en-US').length <= 11) ? 11 - formatNumber(item.valorConsignar, 'en-US').length : 0;
      const line = item.numeroFactura + ' '.repeat(cantFactura) + ' $' + formatNumber(item.saldo, 'en-US') + ' '.repeat(cantSaldo) + ' $' + formatNumber(item.valorConsignar, 'en-US') + ' '.repeat(cantPago);
      // console.log({cantFactura, cantSaldo, cantPago, line});

      result = result.line(line);
    }
    result = result
      .line('-------------------------------')
      .line('TOTAL PAGADO ' + resp.totalPagado)
      .newline()
      .newline()

    }
    result = result
      .line('-------------------------------')
      .line('TOTAL PAGADO ' + resp.totalPagado)
      .newline()
      .line('Estimado cliente.')
      .line('Su pago lo podrá ver reflejado')
      .line('en el portal de clientes')
      .line('www.tiendacolsaisa.com')

      .newline()
      .bold(true)
      .line('Gracias por preferir a COLSAISA.')
      .bold(false)
      .newline()
      .newline()
      .encode();
    // console.log({ result });
    impresora.imprimirEnImpresoraBluetooth(item.id, result);

The funny thing about all this is that if I comment on the line where I use the image, the receipt prints completely.

I attach some videos where you can see the behavior. The first is when the image is used and the second is when I comment the line where the image is used:

2. https://youtu.be/ht_6EegPWU4

Can anyone give me an idea why you may be presenting this and how to fix it?

Thank you very much for your help.

Hi Guys, is this compatible with Angular?
If can, could you help me to share your code from starting add in the module and so on..
Your help will be appreciated sirs.

im trying to printer a double width and double height text which decimal commands are 27 33 32 and 27 33 16 respectively.

i have tried:
.raw([27, 33, 16]).raw([27, 33, 32]) (JUST MAKE A DOUBLE WIDTH, BECAUSE IT IS THE LAST ONE)

then i tried:
.raw([27, 33, 16],[27, 33, 32])

and:
.raw([27, 33, 16, 32])

and:
.raw([27, 33, 16, 27, 33, 32])

nothing works... any clue? thx you so much

i want to print thai characters (CP874) such as "กำลังทดสอบ" . Is possible to specify CP874?
help me please. thank

Thank for very useful library.

I am writing mobile POS app in nativescript.

and i use your encoder. QR code encoded but not printing with 340 characters ?

do you have any solution for long text #qrcode?

i implemented Margin but its not working ,can you provide the sample code
for add left margin bases on pixel or character

Hi,
how can I send the resulting encoding to the printer?
Thanks

Printing text on Epson TM-U220(LAN) works fine, but printing image results garbled text.

The problem is because this printer does not support GS v command (obsolete). To print image, we have to use ESC * command instead.

If it's possible please add support to this print image feature. Thank you.

Após muitos tempo descobri o que causava o erro.
Favor corrigirem

Great project, thanks for your efforts. Does anyone know if it's possible to increase/decrease the font size?

The encode appears to generate an Uint8Array array containing all the bytes. How can I generate ESC/POS commands instead of the byte array?

I've tried print text with GB18030 encoder. But the sign ¥ is printed as 0 6 .
I have no idear what is wrong.

after decoding to utf8, utf16, base64, unicode, I'm not able to print in arabic using EPSON TM-T88IV, the output is coming something like chinese ,any help?

Above QRCode is printing the code type. How to remove this number?

Hi, is it possible to implement table soon?
There is table in documentation (READ.ME) but when you try to use it it return an error "undefined is not a function (near '...-'.repeat(42)).table(['Item 1', '10,00']...')".

I see that table really don't exists in class:
align(value: alignType): EscPosEncoder;
barcode(value: string, symbology: symbologyType, height: number): EscPosEncoder;
bold(value?: boolean): EscPosEncoder;
codepage(value: codepageType): EscPosEncoder;
cut(value?: cutType): EscPosEncoder;
encode(): Uint8Array;
image(element: any, width: number, height: number, algorithm?: imgAlgType, threshold?: number): EscPosEncoder;
initialize(): EscPosEncoder;
italic(value?: boolean): EscPosEncoder;
line(value: string, wrap?: number): EscPosEncoder;
newline(): EscPosEncoder;
qrcode(value: string, model?: 1 | 2, size?: qrSizeType, errorLevel?: qrErrorLevelType): EscPosEncoder;
raw(data: ReadonlyArray | Uint8Array): EscPosEncoder;
size(value: sizeType): EscPosEncoder;
text(value: string, wrap?: number): EscPosEncoder;
underline(value?: boolean | 2): EscPosEncoder;

I don't see how can I put one text align left and other align right on same line. Not to mention situation where I have QUANTITY | PRICE | TOTAL

Can we have something like this soon?
Thanks a lot, good work and keep on rocking!

I'm trying the samples but when I use the text samples I get this error log:
