Ok so I have switched to Code39 barcodes and made the suggested changes to the code, which changes the error that now gets produced. I now get this:

PTN:000-000000:1010001110111010101000111011101010100011101110101000101
+011101110101000111011101010100011101110101010001110111010101000111011

Can't locate object method "Small" via package "GD::Font" (perhaps you
+ forgot to load "GD::Font"?) at /usr/local/share/perl5/GD/Barcode/Cod
+e39.pm line 111, <> line 19.

Here is my new code:

  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";
  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";

As for the suggestions of changing $oGdBar->{text} to $oGdBar->{$text} does not seem to work. Does the error mean I should use GD::Font in my code or is it reffering to the module?
