Using Tk::ROText and Printing http://perlprint.sourceforge.net/

I am trying to set up two printing options from the menu, 1 to print everything in the text box:

$string = $resultbox->get('1.0', 'end');
$printer->print($string);

[download]

The 2nd to print only selected text:

$string = $resultbox->get('sel.first', 'sel.last');
$printer->print($string);

[download]

The issue I am having is determining if anything has been selected before calling get('sel.first', 'sel.last').
Any suggestions?
I tried something like:
if(defined ($resBox->get('sel.first')))

[download]

Which of course spits out the same error as when calling it to get the string with nothing selected.
Tk::Error: text doesn't contain any characters tagged with "sel"
