[Solved] Cups 1.4 Won't Detect Printer

Hello!

I haven't troubleshooted much yet, so please forgive me as I don't have a ton of time right now. I upgraded to cups 1.4 and it will not detect my usb printer. Everything works fine in 1.3.11. I even removed /etc/cups to have fresh config and that still did not help.

I am not sure where to troubleshoot, but until the issue is resolve it might be a good idea to keep cups in testing.

EDIT: It appears that this bug might be related to my issue: http://www.cups.org/str.php?L3318+Qversion:1.4

Cheers,
pyther

Solved with the cups 1.4-2 pkg in testing. You may have to manually unload the usblp module until the devs determine if they want to blacklist it or remove it from the kernel.

I tried compiling with that patch and it didn't seem to help me at all

Re: [Solved] Cups 1.4 Won't Detect Printer

Alright I will do that, I glanced at them before, but I don't believe I had debugging on
EDIT: I probably won't have a change to look until mid day

Not sure if we were experiencing the same issue... but take a look at the bottom of my thread to see how I solved my issue with CUPS not detecting my printer. I ended up having to add it manually.

Re: [Solved] Cups 1.4 Won't Detect Printer

No it is not the same issue. cups 1.4 introduces a new usb backend which makes the backend provided by usblp obsolete.

See http://bugs.archlinux.org/task/15998 for more info

Weird I am able to print with the new cups and with usblp loaded. Perhaps it was fixed in the new udev... I wasn't able to fix my issue before that release was pushed to the repos so I do not know if that fixed something on my end or not.

And you have a usb printer?
And yes the udev update fixed a permission issue which also prevented printing

Well it is a LPT printer but I have it hooked up via a LPT to USB converter cable... not sure what that is considered.
