Cannot print from KDE applications

[Smitty]

I am using suse 8.1 with kde 3.0.4  I have CUPS installed and configured both 
with YaST2 and the KDE control center.  I can print from the command line 
using lpr -Plp /pathtofile   and from staroffice.  I cannot print from kmail, 
knode, or konqueror as a user or as root.  When I click the print icon or 
click print from the File menu, the application freezes.  I don't know what I 
have done to cause this.  Would anyone have any suggestions?
Regards,
