cupsys and kde

[lostbear@softhome.net]

Hi,
I seem to have a problem in getting CUPS to be configured with some
applications of my system. 

I managed to configure cupsys on my system to use a printer on the
network and it works for most of the applications like emacs/mozilla. 

However applications with KDE office suite don't seem to recognize the
configured printer. It just lists four options 

1) Mail PDF file
2) Print to PDF file
3) Print to file (PS)
4) Send to fax. 

When installing cupsys a message approx equal to this was
displayed. 

need to add multicast add this to start up scripts to make things
easier. 

route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0. 

I haven't quite understood the relevance of this and I do add this route
manually every time the system starts. 

I would appreciate if someone could point out to docs or urls to read
about this problem and also explain the relevance of executing the above
command. 

Thank you.
regards
Harshu.
