gmkey/cups-avahi-airprint

Fork from chuckcharlie/cups-avahi-airprint which was forked from quadportnick/docker-cups-airprint

This Alpine-based Docker image runs a CUPS instance with HPLIP drivers that is meant as an AirPrint relay for printers that are already on the network but not AirPrint capable. The other images out there never seemed to work right. I forked the original to use Alpine instead of Ubuntu and work on more host OS's.

Configuration

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 - default is lowercase cupsadmin if unspecified
• CUPSPASSWORD: the password for the CUPS admin user - default is admin username if unspecified

Ports/Network

• Must be run on host network. This is required to support multicasting which is needed for Airprint.

Running

Example run command

docker run --name cups --restart unless-stopped  --net host\
  -v <your services dir>:/services \
  -v <your config dir>:/config \
  -e CUPSADMIN="<username>" \
  -e CUPSPASSWORD="<password>" \
  gmkey/cups-avahi-airprint:latest

Add and set up printer

• CUPS will be configurable at http://[host ip]:631 using the CUPSADMIN/CUPSPASSWORD.
• Make sure you select Share This Printer when configuring the printer in CUPS.
• After configuring your printer, you need to close the web browser for at least 60 seconds. CUPS will not write the config files until it detects the connection is closed for as long as a minute.

Building

If you want to build the files yourself

Build your image using the docker build command, where DH_ACC is your dockerhub account and DH_REPO is your dockerhub repo, and $TAG is the image tag.

docker build -t $DH_ACC/DH_REPO:$TAG . 

In my case:

docker build -t gmkey/cups-avahi-airprint:latest . 

Push your files to dockerhub

Now, you can push this image to your hub by executing the docker push command.

sudo docker push $DOCKER_ACC/$DOCKER_REPO:$TAG

In my case:

sudo docker push gmkey/cups-avahi-airprint:latest
