CUPS: printer's light blinks, but no activity, then stops blinking

DaneM · 11-04-2005, 06:18 PM

Hello, everybody.

I have recently done an "emerge --update world" on gentoo, which updated CUPS from (I can't remember which version) to 1.1.23. Now it doesn't print. When I try to print something, the "busy" light starts blinking, then stops blinking after a few seconds...and nothing prints.

I have tried using a couple of different drivers, and have tried printing with both my printers (HP DeskJet 990cxi and HP LaserJet 5P). The Deskjet's lights don't blink, but I think that it's still getting the document sent to it. (CUPS indicates that the job has been completed/canceled.)

Printing worked before the upgrade, but I don't know how to re-emerge the old version.

Any ideas?

Thanks!

Well, it's still not even remotely working the way it should, but it's doing some differert stuff now. It turns out that emerge didn't actually update cups; it just reinstalled it. Anyhow, now the printers are printing garbage whenever I try to print a test page. It prints one line of random characters, then spits out that page and pulls in another...and another...and another. Only when I reset the printer and kill "parallel" using the "killall -KILL" command does the "printing" stop.

Any ideas what I can do about this?

Thanks.

It seemed to be a problem with my kernel. I downgraded to the next-lower kernel on the portage tree, put hplip in my USE flags, removed gimp-print, hpijs and hpojs, and then installed hplip via emerge. For network printing to work, I had to uncomment

Code:

 application/octet-stream        application/vnd.cups-raw        0       -

in /etc/cups/mime.convs, and

Code:

 application/octet-stream

in /etc/cups/mime.types.

Now it works!

Cheers!

Ok...I've upgraded my kernel again, this time to 2.6.14-gentoo-r5, and I'm now having the same problem. Does anybody know why printing won't work on any of the newer kernels?

edit: disabling Plug and Play ACPI in the kernel and recompiling seems to fix it, but, of course, it disables ACPI. :-( I've submitted a bug report at the request of one of the guys on the kernel.org mailing list.
