like this:

  sudo apt install pandoc wkhtmltopdf
  npm install -g readability-cli
  pandoc -s https://www.paulgraham.com/avg.html -o output.html && readable output.html -o readable.html && wkhtmltopdf readable.html output.pdf &&  open output.pdf

going even further using bash script to prompt for url.

  #!/bin/bash

  # Prompt the user for a URL
  read -p "Enter the URL: " URL

  # Use the URL in the pandoc command
  pandoc -s $url -o output.html && readable output.html -o readable.html && wkhtmltopdf readable.html output.pdf && open output.pdf


  chmod +x web2pdf.sh
  # add an alias to bashrc
  alias web2pdf='/path/to/your/web2pdf.sh'
  source ~/.bashrc
