TableTools wrong export to PDF

imac

Im trying to use TableTools to export the table to PDF but I'm having some troubles with the columns width. They are so thin!! I don't really know why... even when I print them in an A4 they are not so small.

I have also configured it to export it in landscape but still...

Here's an image:

Is there any possible solution for this?
Thanks.
