Find out what is depending on cups.

rpm --whatrequires cups

is the first step. The second is to look at what cups provides and see 
what now is requireing that dependency

/usr/bin/cancel
/usr/bin/lp
/usr/bin/lpq
/usr/bin/lpr
/usr/bin/lprm
/usr/bin/lpstat
LPRng = 3.8.15-3
config(cups) = 1:1.1.17-13.3.6
lpd
lpr
cups = 1:1.1.17-13.3.6

Finally.. make sure your LPRng RPMS provides whatever this bad package 
is wanting.
