2023-11-17 - Version 3.0 - “Quietly Confident”

This is the major release of the new version 3.0. A big thank you to @belono for their many contributions for the finalization of v3!

The third major release of this library drops support for Python 2 and requires a Python version of at least 3.8. The API has been reworked to be more consistent and two new concepts have been introduced:

Capabilities allow the library to know which features the currently used printer implements and send fitting commands. Magic Encode is a new feature that uses the capability information and encodes Unicode automatically with the correct code page while sending also the code page change commands.

The license of the project has been changed to MIT in accordance with its contributors.

The changes listed here are a summary of the changes of the previous alpha releases. For details please read the changelog of the alpha releases.

changes

  • change the project’s license to MIT in accordance with the contributors (see python-escpos/python-escpos#171)

  • feature: add “capabilities” which are shared with escpos-php, capabilities are stored in escpos-printer-db

  • feature: the driver tries now to guess the appropriate codepage and sets it automatically (called “magic encode”)

  • as an alternative you can force the codepage with the old API

  • fix the encoding search so that lower encodings are found first

  • automatically handle cases where full cut or partial cut is not available

  • refactor of the set-method

  • preliminary support of POS “line display” printing

  • add support for software-based barcode-rendering

  • make feed for cut optional

  • implemented paper sensor querying command

  • Include support for CUPS based printer interfaces

  • add Win32Raw-Printer on Windows-platforms

  • add and improve Windows support of USB-class

  • pickle capabilities for faster startup
