[SOLVED] CUPS broken after update

Eurkz · 2021-12-15 16:03:50

Not sure when it broke because I haven't had to print anything in a couple weeks. But prior to this I had my PC connected to cups wireless and it worked fine. Trying to print something today and the printer is not found. You can click on "Print using the system dialog" and it gives me a list of printers. I found mine but when you select it, that status just says "Getting printer information..." and doesnt let you do anything else. Also i cant access the CUPS localhost at localhost:631, all I get is a "Problem loading page" error in firefox.

I set up .local hostname resolution with Avahi and enabled cups.socket
The driver I'm using for my printer is hplip

Has anyone else had this problem recently?

SOLVED: All you have to you is download hplip-plugin and then it will start working again right away.

Cups 2.4.0 update broke the support for many old printer drivers. My Dymo label writer doesn't work with Cups 2.4.0.

Only way to fix the issue is to downgrade cups and cups-library packages to 2.3.3op2-4.

Don't expect it to be fixed. Cups developers intentionally dropped the support for many legacy printers. Such a stupid thing to do.

That printer is only a few years old, that is so dumb

What printer specifically?

Eurkz · 2021-12-17 19:46:13

It is an HP Envy Pro 6400

That thing is barely 2 years old.
You either forgot to update https://aur.archlinux.org/packages/hplip-plugin/ (unlikely) or this is down to the python 3.10 update, though niether would explain why localhost:631 doesn't work.

systemctl status cups

If you've not printed or updated in a longer time, "cupsd.{service,socket}" became "cups.{service,socket}" somewhen this year.

That's what I'm saying! Its still practically new.

This is the output of systemctl status cups

○ cups.service - CUPS Scheduler
     Loaded: loaded (/usr/lib/systemd/system/cups.service; d>
     Active: inactive (dead)
TriggeredBy: ● cups.socket

Well, cups isn't running - you've either not triggered the socket or not enabled the socket (nor obviously the service directly)

systemctl status cups.socket

Edit: please don't copy out of the pager. It doesn't matter here but you're truncating lines what might hide important information in other cases.
In doubt, just redirect the output to a file

Wow I feel dumb. I didn't have hplip-plugin installed. Once I installed It, the problem was fixed. But that doesn't explain why It was working perfectly fine without that package on both computers, then broke several weeks later.

This Is the message I now get running

systemctl service cups
