printing will not align

Hello

 

I have a serious problem which baffles me. I have a design on one layer, and a boundary line around the design on another layer. visually on the screen they both line up . However, when I print the images, they do not line up - they are significantly out of line with each other. It is as if they have been printed to different paper settings., for example the registration marks are not line up.

I will post a screen shot of each image, with guidelines showing that each image is exactly line up on the computor screen.

Can anyone suggest what is happening here? - I have tried 5 or 6 times, and the result is the same.

I am preparing them for a course on laser cutting I am attending for tomorrow, and I am not able to properly prepare cutting files if the cutline wont line up with the image.

I hope someone can help

 

 

Thanks.
