Python library to manipulate ESC/POS Printers

Project description

Continous Integration Code issues Code Health Code Coverage Documentation Status


Python ESC/POS is a library which lets the user have access to all those printers handled by ESC/POS commands, as defined by Epson, from a Python application.

The library tries to implement the functions provided by the ESC/POS-commandset and supports sending text, images, barcodes and qr-codes to the printer.

Text can be aligned/justified and fonts can be changed by size, type and weight.

Also, this module handles some hardware functionalities like cutting paper, control characters, printer reset and similar functions.


This library makes use of:

  • pyusb for USB-printers

  • Pillow for image printing

  • qrcode for the generation of QR-codes

  • pyserial for serial printers

Documentation and Usage

The basic usage is:

from escpos.printer import Usb

""" Seiko Epson Corp. Receipt Printer M129 Definitions (EPSON TM-T88IV) """
p = Usb(0x04b8,0x0202,0)
p.text("Hello World\n")
