Starting services as daemons on Raspbian

instructions.md

• Save the script as /etc/init.d/raspi-printer
• Make it executable chmod +x /etc/init.d/raspi-printer
• Start by doing service raspi-printer start

To run automatically, you run the update-rc.d script:

sudo update-rc.d -f raspi-printer defaults
