What is parallel? The user who runs it is lp. Is it the parallel port? But why is it using the most CPU, when I haven't used anything using lp port?

I believe it is the process that handles the parallel port, yes. If you don't use the port, remove the program. I can't tell you the package because I don't have it installed. -- Cheers / Saludos, Carlos E. R. (from 12.3 x86_64 "Dartmouth" at Telcontar)

Possibly GNU parallel?

Nope, it is running under the lp system user.. it is likely something related to printing. first time I see this "parallel" process running for that use though might be because I have not used computers with parallel ports since a *very* long time. -- "Judging by their response, the meanest thing you can do to people on the Internet is to give them really good software for free". - Anil Dash -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

No, it is parallel lp/printer port.

Anyway: 'ps -lfp 1603' or 'lsof -p 1603' is your friend for finding out more about that process. Or 'ltrace -p 1603' for library calls or 'strace -p 1603' for kernel calls.

ps -lfp helped. ps -lfp 1735 4 S lp 1735 805 2 80 0 - 10087 ? 14:18 ? 00:02:34 parallel:/dev/lp0 440 user http://bolthely.hu That is there is a hanging print command, since the printer is turned off. I checked the print manager before and I could not find pending jobs. This pending job belongs to another user, and it is not shown on the list of my print manager.

lpq -a

If you have only one printer, then lprm ought to clear it. If you have more than one, you'll have to give the name, as it exists in the machine. For example, on my machine, I might have to do lprm HP-LaserJet_2200-2 and that would clear the print queue for that printer.
