It is the same for both, root and mortal users.

No filters are present for root. For mortal users kprinter freezes
and uses 99% CPU when clicking on "Properties".

page_log does not exist and nothing special appears in error_log while
kprinter starts hanging. It only show the long list of printers added
from the CUPS server, one by one ...

Yes, it is kprinter.
The temporary postscript files are written to /tmp/kde-$USER/...
For example trying to print a text file kprinter does the conversion
to the ps file and writes that one to /tmp/kde-$USER/...
but it does not send it to CUPS and hangs instead !

The `funny' thing is that this happens on a Linux cluster, namely 
on the server, while printing from any client via kprinter works
just fine.

No solution found there either...
