There seems to be an issue with the Copyright Attribution text ‘GR’ in the image at GEN 3.6
Change that to the full form “Global Recordings” and it will work again. You will need to click on the “Tidy Up” button on the Help tab to get rid of the old/unwanted settings before you can print successfully again.
I’ve raised this issue of {GR} (=Graphite) with the TeX developers.
