I remember fighting with this kind of issue.
let's see....
OK, I have this in my .bash_profile :

# no default locale, this is BAD and breaks eg normal sort!
#export LC_ALL=C
# commented that to try to use UTF8 (be more modern), and it
# broke printing with evince because the stupid program looks
# at LC_PAPER for that (and prints in letter with the default
# en_US.UTF-8 locale)
# en_GB should print in A4 by default
export LC_PAPER="en_GB.UTF_8"
