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.
