Are you on Windows or OS X? If Windows, no. You need to export a tiff, open in the QTRgui and then print from there. On OS X you can select the quad printer and curves in the standard print dialog box from any application.
Hope that helps,

The thread wandered all over the place. I tried to bring it to conclusion, so if you want to cut to the chase, skip to the last posting to see where I landed with my question. If your question is as straightforward as it seems (is there an interface) then Richard answered it. If you're running into the problems I did, then you may find this useful. Rob
