Printing Width Errors from FlipBook Print Option to PDF

In the ProAdvisor Certification Course, I have been attempting to utilize the print option in the FlipBooks to PDF (Ltr size) [no sense killing more trees than is necessary] but the print result has 2" on the right side missing (like FlipBook is 10.5" wide and the PDF is 8.5") I am under the impression that my view of the FlipBooks and/or entire course is via Flash Player and I actually have the full Acrobat 8 Standard installed in my PC,  not just the Reader version.

So, why is there such a large variance in the printed area page width if they are both Adobe programs?

I have attempted to identify what is causing the errors within the print to pdf option choices and the reading a pdf option choices. But, I have not been able to identify the cause of the variance. It will probably be something very simple that I am overlooking.

Yes, I tried to find an answer at the Adobe website before posting my question here .

Observation  notation: It is interesting to see ProAdvisor and FlipBook are considered spelling errors by the spell check tool within the "Intuit" Community Forum question posting module.
