python-escpos
Python library to manipulate ESC/POS Printers
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has no known vulnerabilities, installs with low friction, uses a permissive MIT license, and solves a real problem for applications that need to control ESC/POS printers. It is well-suited for point-of-sale, receipt printing, and label generation tasks. The main constraint is that you must have a compatible printer and know its connection details (USB IDs, network address, or serial port).AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a compatible ESC/POS printer connected via USB, network, or serial; printer vendor ID and product ID needed for USB connections.
- Low friction install with a wheel distribution.
- Maintains active development (last commit 2026-08-04) and supports current Python versions (3.8–3.12).

What it is and what it does
python-escpos is a Python wrapper around the ESC/POS command set defined by Epson, enabling applications to control thermal receipt printers commonly used in point-of-sale systems. It abstracts the low-level printer protocol, letting you send formatted text, images, barcodes, and QR codes to printers connected via USB, network, or serial interfaces. The library handles printer-specific variations automatically by consulting an external printer database to apply the correct settings for your device model.
The package depends on Pillow for image rendering, qrcode and python-barcode for code generation, and PyYAML and other utilities for configuration. It supports modern Python versions (3.8–3.12) and is actively maintained. Use it when you need to print receipts, labels, or vouchers from a Python application without manually constructing binary ESC/POS commands.
Use it for
- Print receipts and transaction records from a point-of-sale application to a thermal printer.
- Generate and print barcodes or QR codes on labels or receipts for inventory or customer tracking.
- Control paper cutting, font styles, and text alignment on thermal printers from a Python backend.
- Integrate thermal printer output into a kitchen display or order management system.
- Send formatted text and images to network-connected or USB-attached receipt printers in retail or hospitality settings.
