Easily extract and understand data from thermal receipt printers with this C library. It parses generic ESC/POS raw binary data, a common format used by many receipt printers, making it ideal for developers working with digitalizing receipt information.

How to use

This library simplifies working with ESC/POS data from thermal receipt printers. Here's the process:

  1. Define your printer's command set: Identify the specific ESC/POS commands supported by your target printer model.
  2. Parse the raw data: Use the library to parse the raw binary data extracted from the receipt printer. This process will break down the data into individual ESC/POS tokens.
  3. Process the tokens: Iterate through the extracted tokens to achieve your desired outcome. This could involve tasks like image rendering, PDF conversion, or other data manipulation based on your project's needs.
