const { Printer, InMemory } = require('escpos-buffer');
const { ImageManager } = require('escpos-buffer-image');
const connection = new InMemory();
const imageManager = new ImageManager();
const printer = await Printer.CONNECT('MP-4200 TH', connection, imageManager);
Use the WebUSB protocol in Chrome to connect directly to the printer.
import { Printer, Model, WebUSB } from 'escpos-buffer';
import { ImageManager } from 'escpos-buffer-image';
const device = await navigator.usb.requestDevice({
filters: [
{
vendorId: VENDOR_ID,
},
],
});
const connection = new WebUSB(device);
const imageManager = new ImageManager();
const printer = await Printer.CONNECT('TM-T20', connection, imageManager);
const { Image } = require('escpos-buffer');
// Following setup above...
await printer.setColumns(48);
const imageData = await imageManager.loadImage('IMAGE PATH');
const image = new Image(imageData);
await printer.draw(image);
if (feed > 0) {
await printer.feed(feed);
}
await printer.cutter();
await printer.buzzer();
await printer.drawer(Drawer.First);
// For buffered connection (output to stdout)
process.stdout.write(connection.buffer());
// to print, run command bellow on terminal
// For Unix
//> node examples/image.js | lp -d PRINTER_NAME
// For Windows
//> node examples\image.js > output.bin
//> print /d:\\%COMPUTERNAME%\PRINTER_NAME output.bin
