Printing issues using PDF Creator

I use PDF Creator to create PDF files for my heat load calculations using Adtek software.  When I "preview" the PDF file, I have one page/source of information (i.e. 15 pages total).  Yet when I hit the "print" button making a PDF file to then be saved, every other page is "blank" making 30 pages total.  How do I fix this issue?  I do not want to send clients 30 pages when only 15 are needed.






usually this kind of behaviour is caused by the printing application, but we can´t verify this since we don´t have Adtek software.
