[SOLVED] CUPS Being CUPS

y8v · 2026-05-28 03:26:43

I am trying to connect to my printer and this message is displayed(In KDE Settings): "Failed to get server settings: Host is down" I found a reddit post telling me to run sudo systemctl enable cups and I ran that and then this:
[USER@archlinux ~]$ sudo systemctl enable cups
[sudo] password for USER:
Failed to enable unit: Unit cups.service does not exist

I'm confused.

Install https://archlinux.org/packages/extra/x86_64/cups/

also, please use [code][/code] tags, and edit your posts in this regard

Thank you. Still says "Failed to get server settings: Host is down" in KDE settings. The command "sudo systemctl enable cups" worked but did not resolve error.

sudo systemctl enable cups

you configured the service to start automatically on future boots; it doesn't actually start it right now
for future reference, you can use "--now" flag

for now, you just need to explicitly start it

Thank you! It works!

Oh wait, no it does not:
[USER@archlinux Downloads]$ lp -d lpc.gif
lp: Error - The printer or class does not exist.

y8v · 2026-05-28 14:21:23

Also, I am using a Brother MFC-L5850DW series printer. There is probably a driver that I need that I don't have which is why it is giving an error message.

y8v · 2026-05-28 14:27:11

Also, I just checked the Brother website and they only offer Debian and Red Hat packages. I don't know if this means I'm screwed or not.

5hridhyan · 2026-05-28 14:33:38

does it support IPP/IPPS natively?

Edit:
If yes, I dont think you need vendor drivers for it (yet)
I assume you have https://archlinux.org/packages/extra/x86_64/nss-mdns/ and https://archlinux.org/packages/extra/x86_64/avahi/ installed and avahi running
according to https://diiorio.me/posts/cups-server/ try navigating to "https://server-ip:631/admin" on your browser, or "http://localhost:631" and add your printer...

Edit2:
as for the drivers

First of all, the guide at diirio.me is using the apt package manager.
Second, I attempted to install the driver from the github and this happened:

First of all, the guide at diirio.me is using the apt package manager.

I wasn't asking you to follow the guide, I only meant that you should try accessing the CUPS web interface at "http://localhost:631", (or `https://server-ip:631/admin`) and attempt to add the printer from there.

Also, please use `[code][/code] tags for terminal output; large uncoded logs are difficult to read.

As for `lp -d lpc.gif` that is not valid syntax. `-d` specifies the destination printer name valid syntax would be "lp -d PRINTER_NAME file.gif" after the printer has actually been added to CUPS.

Regarding the driver package; the build itself completed successfully. "exists in filesystem"
which means some Brother files were already copied into `/opt/brother/...`, so pacman refused to overwrite unmanaged files.
You can either remove those files manually and reinstall the package, or use pacman's overwrite flag.
also it was proposed as a "fallback", not a step 1 thingy to try...

Edit:
re-wrote the whole post, as the previous version was unnecessarily aggressive
FUCK MY LIFE
