Would be cool if it hooked into Home Assistant to automatically switch the printer on and off.

[matteos1]

there is a add on for cups?

[hugodelaroza]

It would be great to have an addon to share an old usb printer to the network and use hassio raspberry as a print server

[vijaynaru]

Looking for the same.
thanks

[matteos1]

is there any hope to see this add on?

[dereitz]

I'm guessing there's only hope if enough people comment and/or provide a thumbs up...

[MatteoGheza]

Any update on this?

[magenbrot]

This would be a cool addon. Imagine having a printer powered by a switchable outlet, only turning the printer on when there's a job in the cups printing queue waiting :)

[yousaf465]

What's the update on this?

[andriej]

One of the most-missing addons I guess. :-)

[Hubberthus]

Found an unofficial addon for this.
I've searched the net for days, bumping in dead ends like this thread until I've stumbled upon the following, so I'll share it for those who are interested.
It works for me, just tested it out. Unofficial so use at own risk.

[Monacoslo]

Is this addon just to monitor CUPS or does it allow connecting printer directly to the computer with HA without installing CUPS server?

[hugodelaroza]

I installed it, but when I try to access the web interface I get: 502 Bad Gateway nginx/1.18.0 Can you help me? El jue, 23 dic 2021 a la(s) 12:56, Hubberthus ***@***.***) escribió:

I had to go to the page at port 631 of my Home Assistant server because Ingress page isn't working well.

[oraculix]

I can second that. In my case I suspect a conflict with the already running nginx add-on.
After disabling SSL in the configuration, it works both in the integration and with "http://homeassistant.local:631". The latter is a bit unsafe, though, but I can live with that until someone posts a solution to the "Bad Gateway" issue.

CAVEAT: Some printing services (e.g. newer Android) require SSL, so a solution to this issue would be desirable.
Ironically, though, Windows 10 still can connect via HTTP only as it seems (source).

[yousaf465]

can you share some screenshots, how did you manage to get it working?

[oraculix]

No time to shoot screens atm, but it is pretty simple:

1. Go to Settings --> Add-ons --> "CUPS print server" and there to "Configuration".
2. The very first settings is the "SSL" switch; turn it off.
3. A little further down, press the "Save" button and then "Restart" in the following dialog.
4. After a few seconds, open http://homeassistant.local:631/ (or use HA's IP address)

Yes, I disabled SSL and could see web interface, but It seems it doesn't have drivers for my old HP Laserjet 1020 El jue, 23 dic 2021 a la(s) 14:21, Matteo Gheza ***@***.***) escribió:

There was no driver for my printer as well, but printers mostly work on the same basis, so as long as it is pretty much the same kind, it's okay. I'm using an L310 driver for my Epson L3211.

Actually, I can see a driver in the list for your one. Scroll to the middle of the list, and there are several ones for the Laserjet 1020. There is one with "recommended" next to it, my guess it it will work. The "requires proprietary plugin" ones won't work I guess.
But even if the "recommended" one doesn't work for some reason, you can try the "Laserjet 1010 - CUPS+Gutenprint" one. I'm using a Gutenprint driver, and it works.

If you'd like to use it from a Windows machine, when you add a network printer use the link to the printer's CUPS page.
For example for my printer it is:
"http://homeassistant.local:631/printers/EPSON_L3211"

Then when it asks for driver I'm not sure it should be the driver for the actual printer as it is a CUPS network shared printer, so I just selected the "Microsoft PS Class" driver.

[xCeLeSx]

@Hubberthus I used that same driver for my L3210. DO you have more details in HA Sensor for this printer or only current status? Could we check ink level?

[Hubberthus]

It's been a while when I used this. Bought a wifi printer 2 years ago and all this became obsolete for me instantly.
But my guess is that the interface towards the printer is very limitied with this addon, so you most propably won't be able to check the ink levels.

[LarsNorgaard]

You could maybe use https://www.debugpoint.com/printer-ink-levels-linux/ and then have a script run that extracts the ink levels to home assistant.

[hugodelaroza]

Hi, sorry for my delay. Thanks for your help. I´m a windows user, I´m not familiarized with CUPS. I connect my printer (HP Laserjet 1020) on USB port and start the addon, then I go to administration\add printer and I don´t see my printer there...

Ah, I see.
If you mean the very first step with the radio buttons, I guess you should select "HP Printer (HPLIP)" in the "Local Printers" section.
After that page, that's a tricky question...
I've googled around, and maybe if you use the "socket://homeassistant.local:9100" or "socket://localhost:9100" on the next page it could work. Apparently HP printers tend to use this.

(The best way would be to run the "hp-toolbox" command to set up the printer automatically for CUPS, but the problem with this is that the addon runs in a separate docker, so you can't just do that. This whole CUPS thing is basically best when run on a Unix machine directly, and not as a Home Assistant plugin. I hope the "socket://..." will work for you)

I have another issue with ncarr addon ncarr/addon-repository#3
Did anyone have a similar problem?

[andriej]

Same here

[LarsNorgaard]

This works for x86:

working on raspberry pi 4.

[crisjff]

Works for me: raspberry pi 3b+ haos x64 with canon MG5100 usb connection.

[GHGiampy]

Someone is currently running a working cups server on a RPI3 (1GB of RAM) on HA 2023.09.3, HAOS 10.5?

[Monacoslo]

This one works great. Just install it as custom repository and you are done!
That is something we needed.

[kissi7]

@Monacoslo
how did you get password for user "print"? (I had to enter to the container and reset it)
where you able access /admin page with out changes in "location" section in cupsd.conf? (I had to change @Local to "all")
if you add printer does it survive the HA reboot? I see there is not persistent config :(

I am using HA OS.

[LarsNorgaard]

Username is print and password is print.
Settings survive reboot and such.

[zajac-grzegorz]

Config is now persisted in /data/cups folder.
