How to use OMV as print server?

use this working cups.yml

networks:
  my-net:
    external: true
services:
  cups:
    container_name: cups
    networks:
      my-net:
    image: olbat/cupsd:latest
    volumes:
      - /var/run/dbus:/var/run/dbus:ro
      - CHANGE_TO_COMPOSE_DATA_PATH/Dockers/cups:/etc/cups
    ports:
      - 631:631
    restart: unless-stopped

note: my-net is the bridge network that i use on all my dockers so can be resolved by swag, use it or delete apropiate lines like:

services:
  cups:
    container_name: cups
    image: olbat/cupsd:latest
    volumes:
      - /var/run/dbus:/var/run/dbus:ro
      - CHANGE_TO_COMPOSE_DATA_PATH/Dockers/cups:/etc/cups
    ports:
      - 631:631
    restart: unless-stopped

you need to post the logs to see what is faulting.

only thing that i can imagine is that "CHANGE_TO_COMPOSE_DATA_PATH/Dockers/cups" do not have enought privileges to write on it.

Works by deleting this whole line (with path amended):

- CHANGE_TO_COMPOSE_DATA_PATH/Dockers/cups:/etc/cups

If you had the line constructed correctly, it should have worked, as it is just mapping a directory into the container for data persistence. The fact that it is a directory mapping is invisible to the container.

To use OpenMediaVault (OMV) as a print server with Docker, you can set up CUPS (Common Unix Printing System) using the Docker image olbat/cupsd. Start by pulling the Docker image with the command docker pull olbat/cupsd. Then, create a Docker Compose file similar to what you used for Plex and qBittorrent. Include necessary configurations for CUPS like port mapping (e.g., 631:631 for web interface access) and volume mapping for persistent data. Once the Compose file is ready, deploy it through OMV’s Services > Compose section, and access the CUPS web interface to configure printers.

You should also add usb into your Volume section of the compose file to add an USB printer.

    volumes:
      - "/dev/bus/usb:/dev/bus/usb"
      - "./cups:/etc/cups"
      - "/var/run/dbus:/var/run/dbus"

Also having /etc/cups as a volumes make sense, otherwise you have to add your printer after every container restart

Hi, on the old instance I've used cups directly installed on the omv/debian, but this made some mess in logs, etc

So as I'm doing everything from zero (fail of the disk), I probably also would prefer to do this via CUPS in docker, to have it isolated

But I have HP1005 (old HP printer, very good stuff) for which I need to do in the system some nasty things (like installing hplips, foo drivers, etc)

It can be done also in docker installaiton?

yes, but you need to define a writable path like described on post #4

This is clear and obvious, as for any other docker (or most) persistant volume is needed.

I rather thinking of how to install those additional packages to not loose them - as they will not be stored on this volume I think.

Have look at this docker image of cups

olbat/cupsd Image

it has most of the stuff you need already included.

I'm trying to install it using following compose but it looks it is not starting at all

In portainer is described as "running", but there is nothing in "ports" to click and open GUI and also port 631 is not used anyway, also logs are empty.

Of course path for variable CONTAINERS_DATa is correct

Logs of container are empty:

No log line matching the '' filter

Any ideas what's going on?

Above 30docker apps installed without problems, but this one, which looks like piece of cake, doesn't work

edit:// fixed by puting .conf file into the persistant volume, as with it, cups is not creating it with first start.

Now it works, but is not finding my printer - I added devices by:

      - /var/run/dbus:/var/run/dbus:ro
      - /dev/bus/usb:/dev/bus/usb

Try to plugin and switch on your printer first.

Then start the container.

You should then find your printer.

Hope that helps

Nope, it was needed to run it with --privileged flag

After that it discover my printer, but it can't be used for my case, as this not container hp-plugin which is needed for my device.

Looks that will not be possible for me to use this docker app

As I couldn't solve issue with hp-plugin on docker image of CUPS, I decided to put CUPS in my LXC container, used for another purpose.

After configuration, I works like a charm, but unfortunately when I switch off my printer and container needs to reboot (for example after power break) it can't, becuase of issue with missing USB device

My config for the USB is:

<hostdev mode='subsystem' type='usb' managed='no'>
<source>
<vendor id='0x03f0'/>
<product id='0x3d17'/>
</source>
</hostdev>

Error output:

Unable to - poweroninternal error: Did not find USB device 03f0:3d17

OMV\Exception: Unable to - poweroninternal error: Did not find USB device 03f0:3d17 in /usr/share/openmediavault/engined/rpc/kvm.inc:2606

Is it possible somehow to make this USB as "optional" so the LXC will start no matter is the USB device is present or not?
