This problem (or a closely related one, I can't tell) is still not (fully?) fixed in:
DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION="Ubuntu 11.10" using cups-1.5.0-8ubuntu6 Here is some more detail than given above: Printers defined locally that are not connected/accessible, whether by USB or directly on the net, do not cause a problem. However, a remote CUPS server defined in /etc/cups/client.conf like this: ServerName print.mpia-hd.mpg.de causes a hang of 3-6 minutes if the server is not there. For the record, this server serves 72 printers, and the longest measured timeout was 6 minutes, 19 seconds. It does not matter whether the default printer is one of the missing ones or not. Applications hang in predictable ways: the print dialogue in gnome, which Firefox and Chromium use, causes that entire browser to hang while waiting, even if all you want to do is print to file. If you want to change the default printer with lpoptions, you can't, because it hangs, times out, and quits. If you know the printer you want to print to and specify lpr -P foo bar.pdf, it hangs. So does lpq, and so on. However, the localhost:631 interface is *unaffected*, and can print test pages without delay. Removing the client.conf file and restarting CUPS fixes the problem immediately. So, a workaround is to manually create and remove that file every time you enter/leave the network with the print server. My guess is that few people think they are experiencing it because the timeout depends on how many printers were served on the missing server, and most don't have that many. This looks like it should be a simple fix of querying the printers in parallel and giving them a few-second timeout. I very much hope this will be fixed! There do appear to be others experiencing this, but there is little clarity on the web about it (some scattered complaints but few solutions that are practical).
