WP2PDF – Want to pass page slug

the call to wp2pdf already passes in the current post ID, but it also lets you pass in other info in its M variable which you can use for the resulting PDF’s title. i’ve been trying to pass in the page’s slug for this, but havn’t been able to get it to work.

wp2pdf.php?p=<?php the_ID(); ?>&m=<?php post_name ;?>

the above just gives a blank M variable. I’ve had “get_title()” in there, and that works as long as i don’t have anything like quotes in the title. the slugs are clean and file-name-friendly, which is why i want to use them. Is there a get_pageslug() function that i’ve missed? I’ve looked through the function lists about a dozen times and havn’t found anything to help ??
