The full story
A ZEITEL SC03h pocket thermal printer, bought for about ₹1,000, could only be used through the vendor's phone app, which asked for odd permissions and was hard to use. The printer sat idle.
The owner built NuPrint, a free and open-source desktop app in Rust and Tauri that prints notes and pictures from Windows, macOS and Linux, tested on all three. Partway through they found these are known as cat printers; at that point they handed the work to Claude and Codex to finish, then fixed many remaining issues themselves.
The printer can now go to the nephew it was bought for.
