# ngxson/esp32-usb-to-airprint

> Firmware for ESP32-S3 that plugs into an old printer's USB port and makes it wireless: printing via AirPrint/Mopria and scanning from a browser or macOS.

- Magnitude: 4.8 out of 10 — Early signal
- Stars: 118 total · +16 stars measured 2026-10-27, 09:12–10:52 UTC, ≈ 50 by evening
- Star trust: star growth looks organic
- Category: Hardware, IoT & robotics · Language: C · License: MIT · Created: 2026-10-26 · Last push: 2026-10-26

## Useful for

- Connect an old Canon PIXMA to Wi-Fi and print from an iPhone without drivers
- Scan documents from the printer directly in a phone browser
- Combine several scanned pages into one PDF via the built-in web app

## Why it’s here

- Star-counter measurements on 2026-10-27 (UTC), 09:12–10:52: 102 → 118 stars (+16). This is the change over that interval.
- Estimated end-of-day forecast: about +50 stars, using observed gains and the previous day.
- The repository is 1 day old and already has 118 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- About 8 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 6
- Issues and pull requests: 4
- Watchers: 0
- Average over the last week: 70 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 2

## Stars per day, last 2 days (oldest → newest, today is partial)

2026-10-26 … 2026-10-27: 89, 16

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
