+# Receipt Maker
+
+Prints random images from 4chan's /bant/ board to an Epson TM-T20II thermal receipt printer over Ethernet.
+
+## How it works
+
+1. `connect_recipt.sh` — configures the network interface and connects to the printer at `192.168.192.168:9100`
+2. `receipt.py` — CLI with subcommands to print random /bant/ images, text notes, or local images (resized to full printer width, 576px)
+
+## Requirements
+
+- Python 3
+- `python-escpos`
+- `Pillow`
+- `requests`
+- `nmap` (for connection script)
+- Epson TM-T20II connected via USB-to-Ethernet adapter
+
+## Usage
+
+```bash
+# Print a random image from /bant/
+python receipt.py image
+
+# Print a text note
+python receipt.py note "your message here"
+
+# Print a local image (with optional caption)
+python receipt.py print path/to/image.jpg
+python receipt.py print path/to/image.jpg "optional caption"
+```
+
+The script will run `connect_recipt.sh` automatically to bring up the network interface before printing.
+
+## Files
+
+- `receipt.py` — main script
+- `connect_recipt.sh` — network setup for USB Ethernet adapter
+- `img/` — downloaded images cache
+- `img_fullwidth/` — resized images ready for printing
