They are overwritten by system-config-printer, which is probably called 
from postinstall part of cups package.  You either configure cups by 
hand (and remove system-config-printer and system-config-printer-gui), 
or you don't touch any files in /etc/cups and let system-config-printer 
take care of them.

Same goes for all other packages from system-config-* category.  You 
either remove the package and configure things by hand.  Or you install 
the package and do not touch generated configuration files.  It's all or 
nothing.

If you don't have system-config-printer packages installed, then you 
should report bug against cups RPM package (those two files should be 
marked as noreplace).
