## What it is
A Node.js ESC/POS printer driver library for controlling thermal receipt printers. It provides a printer API plus adapters for USB, network, Bluetooth, and serial port connections.

## Use cases
- print receipts from a node.js app to a thermal printer
- print barcodes and QR codes on an ESC/POS printer
- connect to a receipt printer over USB, network, bluetooth or serial
- build a point-of-sale printing feature in javascript
- format tables and text on a thermal receipt printer

## When to choose
- you need to drive ESC/POS thermal printers from Node.js
- you want multiple transport adapters (USB, network, serial, bluetooth) in one ecosystem
- you need barcode, QR code, and table printing support

## When to avoid
- you are not using Node.js or JavaScript
- you need a non-ESC/POS printer protocol
- you need a GUI printing solution rather than programmatic control

## Facets
- artifact type: library
- maturity: active
- function: sdk
- domain: hardware, developer-tools
- platform: cross-platform
- tags: escpos, thermal-printer, receipt-printing, usb, bluetooth, serialport, barcode, qr-code, hardware, automation, nodejs
