Sorry, nothing I'm aware of. I'm hoping to add some advanced print functionality to the map in the near future (time permitting), but you can easily overlay kml (from Google Earth etc.) on to the map and take a screenshot to print out at present. Look at the "Share" tab for kml options. Not the most elegant solution I know, but might work for you for now?
Do you tend to save waypoints and tracks as kml? I could easily add a feature to the map that allows you to upload your own. And if you can put the kml elsewhere online e.g. Dropbox - http://db.tt/6aAdmCO
then you can use the existing functionality under the "Share" tab.
Let me know if you need help / get stuck - use the Contact option on the http://www.topomap.co.nz
and I'll help you out.
