First small issue: get rid of the print in print My::Test::Print::printer() ."\n";. That at least gets you the "This is" part of your printer sub to spit out... .

update: I did the following which seemed to work:

#!/usr/bin/perl
use strict;
use warnings;

package My::Test;
our $VERSION = 1.11;

package My::Test::Print;
#parent My::Test;
sub printer {
        print "This is ". $My::Test::VERSION ."\n";
}
My::Test::Print::printer() ."\n";
my $test = 1.23;
print "test: $test \n";

Output: This is 1.11

test: 1.23
