# wifi-printer
# Wi-Fi Printer
Thermal printer automatically prints addresses and vendors of Wi-Fi devices nearby.
This project prints all SSIDs, MAC addresses, and their vendors on a thermal printer using a Wi-Fi adaptor in monitor mode.
## Overview
## Usage
1. Setup a Raspberry Pi with Raspbian/Raspberry OS
2. Connect to Internet
3. Run ``install.sh``-Script
4. Wait
5. Set up for further usage, i.e.:
* Remove Internet connectivity (not needed anymore)
* Connect printer and Wi-Fi adaptor
* Include everything into nice device :)
## Important
* You might need to adapt the printer configuration in ``cms.py`` depending on the printer you use
* You might need to change the name of the network adaptor in ``install.sh``
