print and return do completely different things. By default the return value of a perl subrouting is the return value of last evaluated statement. The return value of the print statement is "1" (if it succeded, which is likely always) and the return value of return statement ist the variable you passed to it (or undef if nothing has been passed).

Take a look at this code: 

 #perl
my $variable = 234;

sub ax {
   print $variable;
   print "\n";
  }
sub bx {
    $variable;
   }
   
my $return_val_a = ax();
print "a - [$return_val_a]\n";
my $return_val_b = bx();
print "b - [$return_val_b]\n";

This will produce this output: 
234
a - [1]
b - [234]

where you can see the difference a() returns one and b() returns the valus of the variable.
