CUPS printers disappear every time

[stiv2k]

This problem has been ongoing for at least a month now. It is not printer-specific, as the same thing occurs with my old HP PSC 1310 and this new Lexmark X1270. What happens is I will add the printer, it will work fine for a couple hours, I'd go out and do something, come back, and BAM, printer is GONE. I have to manually re-add it every time.

my setup is as follows:
- The printer is connected to my server running Feisty attached via USB cable
- Cups 1.2.8
- The only relevant output i seem to find from the Error log is as follows:
D [20/Aug/2007:06:30:36 -0400] Discarding unused printer-deleted event...
D [20/Aug/2007:06:30:36 -0400] Remote destination "Lexmark_Printer" has timed out; deleting it...

- CUPS config:

# file.

PS: This all started when I reformatted the drive on my server. Before that it was working quite perfectly. What could be causing this?? I really need to get it working soon as school has started and me and my room mates will be relying on this printer to work. Thanks in advance

Have you found out what happened ?

I experience a similar problem on one of our servers... just wondering... have you by any chance a machine which is known as some name in its /etc/hosts and differently in the DNS resolving (reverse resolving from its IP)... I'm just suspicious about local print queues being recognized by the server as remote ones, and thus causing removal problems after some time(out) maybe.

Hope this helps,

Is this symptom still reproducible in 8.10 beta or later?

[stiv2k (stiv2k)]

I don't think so; I have not had this sort of problem for several months
now, it is probably safe to mark this bug as CLOSED; I am not exactly sure
what happened to suppress the issue.
