Problem for printing with a tracer HP

Hello all,

Normally I use autocad, but i have a new computer with seven and my autocad don't works.

And now I use the Drafsight, but I have a big problem, I can't print on my tracer.

I don't understand why, when I clic print, i see well on windows print but it disappears.

If you have an idea, thanks.

Sorry for my bad english.

 

Best regards.
