How the printer hacking scene invented its own DRM

This Habr article explores the history of a Russian and Ukrainian hacker community that specialized in cracking laser printer firmware. The core issue involved cartridge chips that blocked printing after a set number of pages, forcing users to purchase new supplies. Enthusiasts developed patches to bypass these restrictions, effectively creating a market for 'unlocked' firmware. Interestingly, to protect their work from unauthorized distribution, the hackers implemented their own DRM system within their patches. The author reconstructs these events using archived forum data, highlighting a unique niche in information security that is rarely covered in Western publications. It is a story of how the struggle against corporate limitations led to the creation of a complex ecosystem for hacking and protecting software for peripheral devices.
