docker-cups-airprint-suldr

This Ubuntu-based Docker image runs a CUPS instance that is meant as an AirPrint relay for old Samsung printers that are already on the network but not AirPrint capable. It includes the Samsung Unified Linux Driver from the The Samsung Unified Linux Driver Repository.

It will generate a service file for the Avahi daemon. Note that the Avahi daemon is not part of this container though. It assumes that an Avahi daemon is running on the host and the /etc/avahi/services directory is mounted into the Docker container (see “Running” below).

See https://www.bchemnet.com/suldr/supported.html for a list of supported printer models.

Building

docker build . --build-arg SULDR_PACKAGE=YOUR_VERSION_HERE -t docker-cups-airprint-suldr

Replace YOUR_VERSION_HERE by the correct driver version for your model (see https://www.bchemnet.com/suldr/supported.html for an overview). If you omit --build-arg SULDR_PACKAGE, it will default to suld-driver-4.00.39 (which the correct version for the Samsung CLP510-N that I own).

Running

docker run --name docker-cups-airprint-suldr --rm -p 631:631 \
	-v /etc/avahi/services:/services \
	-v /home/aaron/config:/config \
	--env CUPSADMIN=admin --env CUPSPASSWORD=admin \
	-t docker-cups-airprint

Update the paths to match your setup.

Note that this assume that Avahi is running on your host computer!

Configuration Reference

Build Arguments

Set the following to include the correct driver version:

• SULDR_PACKAGE (example: suld-driver-4.00.39)

You should be able to leave these unchanged as they have reasonable defaults:

• SULDR_REPO
• SULDR_KEYRING_URL
• SULDR_KEYRING_DEB

Volumes

• /config: where the persistent printer configs will be stored
• /services: where the Avahi service files will be generated

Variables

• CUPSADMIN: the CUPS admin user you want created
• CUPSPASSWORD: the password for the CUPS admin user

Ports

• 631: the TCP port for CUPS must be exposed

Notes

• CUPS doesn’t write out printers.conf immediately when making changes even though they’re live in CUPS. Therefore it will take a few moments before the services files update.
• Don’t stop the container immediately if you intend to have a persistent configuration for this same reason.
