Help Cutting Large Logos in Corel with Graphtec

Hello Everyone! 
My name is Adam and I just started a Automotive vinyl company. I am learning a lot and a lot of it is trial and error. I have now sent multiple images etc. to my new Graphtec 6000 24 Cutter. 
I am having one issue that I can not figure out to save my life. I am using Corel Draw 6. When we go to print a logo or to make graphics for our company car, we can't print anything over a normal legal size piece of paper. I have looked through all of the settings and can't figure it out. Does anyone know of any tips or tricks or the proper procedures to get this going in the right direction for us?
We appreciate your help!
