This application monitors your Twitter home timeline or any number (within the Twitter API limits) of hashtags of your choice and prints all incoming Tweets via an ESC/POS compatible thermal printer.
This application has been developed and tested on Linux, targeting python3.6 or newer. It might work on macOS (likely) and Windows (very unlikely).
Create a virtualenv with the required dependencies
python3 -m venv venv venv/bin/pip install -r requirements.txt
Getting Twitter API access
- If you already have access enter your consumer key/secret and access token/secret in the next step.
- If you don't have such credentials you must create a Twitter App and get the required information after you've created it.
Create and fill in config.toml
cp config.toml.example config.toml $EDITOR config.toml # Put the required information into config.toml
Besides the already mentioned API credentials the config.toml contains other (interesting) settings. For each setting there is a short explanation on what the setting does and what the default value is if the setting is not defined.
Check your thermal printer
- Ensure it supports ESC/POS.
- See if your operating system detects your printer (look at the output of dmesg).
- Check if the user that will be running this application can access the printer (check
ls -l /dev/usb/lp*,
- A line width of 48 characters and Latin-1 as printer codepage 6 are assumed.
- This application was tested with a Excelvan/Hoin HOP-E801 printer. No other models/printers have been tested yet.
Printing your home timeline
venv/bin/python3 printer.py --printer /path/to/printer
If you don't want to see retweets make sure to include the
--no-retweets option in the command line above
Printing a specific (or multiple) hashtags
venv/bin/python3 printer.py --printer /path/to/print "#hashtag1" "#hashtag2"
If you want to see retweets in this mode make sure to include the
--retweets option in the command line above
You can test this application without a thermal printer connected by simply omitting the
--printer argument when starting it. In that case you'll just get the output in your terminal.
