Cutting on Roland Camm-1 using Coreldraw X6

Hi. We are using Coreldraw X6 and I make Maserati lettering by tracing a photo. I deleted the photo and outline remains but when I tried to print it using the Roland Camm-1 it is not printing. Kindly let me know what is the problem on this. I tried exporting file into .plt but still it is not printing.
