This project implements a subset of Epson's ESC/POS protocol for thermal receipt printers. It allows you to generate and print receipts with basic formatting, cutting, and barcodes on a compatible printer.

The library was developed to add drop-in support for receipt printing to any PHP app, including web-based point-of-sale (POS) applications.

支持所有通用标签打印机机型
