CUPS gives host not found error

Hi

I got CUPS running and it seems to work fine, but when I try to print something, KDE, initializes the printing manager and says:

Unable to retrieve the printer list. Error message received from manager:
Connection to CUPS server failed. Check that the CUPS server is correctly installed and running. Error: host not found.

I know it's running, I enabled it trough init and ran cupsd as root. The strange thing was that CUPS was working before, this probably is because of an update.

Run ps and/or netstat and make sure the daemon really is running and listening for connections. Also, check your local localhost interface and make sure it's properly configured?

ok, i got the error sorted out, but when I try to print, the printing system freezes, error log shows:

It loops there for a while, then the printing system responds. Then it never prints the file. :(

Did you ever find a fix for this? I have the same problem on Debian Etch and it's driving me crazy.

iirc, I fixed it by downgrading to the previous cups version. Unfortunately, it's long ago, so I'm not completely sure.
