in thread Need some help with GD::Barcode::UPCE module

I couldn't replicate your error. As for $oGdBar->{text}, that is the correct way to do it. Try this and see if it helps: 
#!/usr/bin/perl

use strict;
use warnings;
use GD::Barcode::Code39;

my $oGdBar = GD::Barcode->new( 
              'Code39', '*123-456789*' );
print "PTN:", $oGdBar->{text}, ':', 
              $oGdBar->barcode(), "\n";
open OUT, '>', '/tmp/Code39.png';
binmode OUT;
print OUT $oGdBar->plot->png;
close OUT;
undef $oGdBar;

    Even after changing my $oGdBar = GD::Barcode::Code39->new() to my $oGdBar = GD::Barcode->new() I still get the same error. I checked to make sure my GD::Barcode module is current and CPAN says I have version 1.15 installed

      You still get the same error because you're still making the same mistake:). You'll need to change more than just new(). Post what you have now, then we can figure out what's wrong.

        Ok well there is what I have currently

        #!/usr/bin/perl
use strict;
use warnings;
use GD::Barcode::Code39;

  my $oGdBar = GD::Barcode->new('Code39', "*$customer{id}*");
  #my $oGdBar = GD::Barcode::Code39->new("*$customer{id}*");
  if ( !$oGdBar ) {
   display_menu_error("ERROR: $GD::Barcode::Code39::errStr \n");
  }
  print "PTN:", $oGdBar->{text}, ":", $oGdBar->barcode(), "\n";

#FIXME prints out error "Can't locate object method "Small" via packag
+e "GD::Font" (perhaps you forgot
#to load "GD::Font"?) at /usr/local/share/perl5/GD/Barcode/Code39.pm l
+ine 111, <> line 19."
  my $output = '/tmp/Code39.png';
  open my $OUTFILE, '>', $output;
  binmode $OUTFILE;
  print {$OUTFILE} $oGdBar->plot->png;
  close {$OUTFILE};
  undef $oGdBar;
  undef $OUTFILE;
  undef $output;
  system "lpr -r $output";

        Not sure what mistake it is I am making here, I thought I followed the documentation to the letter. Ether way the barcode is being generated I can tell this because of the output from $oGdBar->barcode(), but the /tmp/Code39.png file is empty.
