Laser Engraver

When I was first told about the laser engraver I was told that I should always bring a PDF document to print. While looking through the epilogue website I see that you are supposed to be able to print in any format. Has anyone ever printed anything besides a PDF document? Would we have to set up the computer to do something different if we want to use a different file format? I am interested in printing some things that were drawn in autocad but am having a lot of trouble converting them to PDFs. I have scaling issues, and sometimes the drawings are just messed up once converted. Any thoughts would be greatly appreciated.
