Some alternatives - consider a map statement for the inner loop and consider a heredoc for the title. You could probably make the header separator a static too. Something like (not tested): 
sub printSettings {
    my @groups = shift;
    my $sep = "=" x 60;
    foreach my $table (@groups) {
        foreach my $info (@$table) { 
            my $cnt = 1;
            print <<EOF;
$sep
     $info->[0]
$sep

EOF

            print map { sprintf "%5s.   %-25s %-5s $info->[1]\n", $cnt
+++, $_;} sort keys {$info->[1]};
        }
    }
}
