The font6x14 is rarely a standalone "library" in the modern sense (like a npm or pip package). Instead, it is a legacy header file found in various embedded graphics repositories.
Option 1: The GFX Library (Recommended) The easiest way to get this font is to download the Adafruit GFX Library or similar display drivers for Arduino/ESP32. While they default to a 5x7 font, they often include larger fonts, or you can use tools to generate the specific 6x14 header.
Option 2: Direct Code Snippet
Below is a generated sample header file containing the basic ASCII set (Space through Tilde). You can copy this code and save it as font6x14.h in your project.

Option 3: Font Generation Tools
If you need a specific style (Bold, Serif), it is best to generate the .h file yourself.
The standard 6x14 font loops through 14 rows and checks 6 bits. This is inefficient for real-time graphics. If you need to print hundreds of characters per second: The font6x14 is rarely a standalone "library" in
Since the height is 14 pixels, a single character column cannot be represented by a single byte (8 bits). Therefore, each column requires 2 bytes (16 bits), with the bottom 2 bits typically unused (padded with 0).
Many bare-metal graphical tutorials provide a direct copy. A quick search on GitHub Gists for 6x14 font bitmap will yield verified copies. Always check the license (usually MIT, BSD, or Public Domain).
