I've tried this in seamonkey, mozilla-firefox, and epiphany, all with the same results. I go to request a print dialog (or print preview) and the browser freezes. I've gone into the CUPS web interface and can print a test page there, but the browser still freezes when I request File->Print. Reproducible: Always Steps to Reproduce: 1. Open a netscape-based browser 2. Request File->Print 3. Actual Results: Browser freezes Expected Results: Job should have been sent to the printer catherine ~ # ps ax | grep cups 18139 ?

When I try to print in Konquerer, it gives me a message: An error occurred while retrieving the printer list: Connection to CUPS server failed. Check that the CUPS server is correctly installed and running. Error: catherine.espersunited.com: read failed (15).An error occurred while retrieving the printer list: but doesn't freeze up like the netscape browsers do. I've checked and rechecked the cups configuration against the Gentoo Printing Guide, and it all checks out. Plus, the printer used to work with the exact same configuration.

Still the gnome thing wouldn't explain why konquerer claims it can't talk to CUPS. Also, running gnome-cups-manager at the terminal doesn't provide a GUI, just a blinking cursor...

Created attachment 153589 [details] strace of gnome-cups-manager This is the output of strace gnome-cups-manager , at least until I aborted it...
Looks like it's waiting on a lock (futex). Do the command line apps (lpq, lpr, etc.) work at all? Or do they hang too? lpq is the easiest to check. Also, can you connect to the cups web admin interface? It's at: http://localhost:631/admin
I don't understand exactly how this happened, but I upgraded cups to 1.3.7-r1, replaced the config files with those suggested by emerge, and restarted the server, and now it works correctly. Maybe the problem was with my previous config files?
