Evolution 2.8 uses the deprecated libgnomeprint for its printing API,
which is likely where the problem lies.  Evolution 2.10 migrated to
GTK's printing API [1].  GTK's printing API may have addressed this
issue, I'm not sure.

In either case, Evolution itself is not doing anything that would bypass
CUPS security.
