[daisy] Pages in published PDF books at 11 x 17

[ted.marquardt at thomsonreuters.com]

Hi, 

Using Daisy 2.1, when I publish a book, the pages of the PDF output are
sized at 11 x 17 instead of 8.5 x 11. I searched through the Daisy
documentation for a setting that controls this, but had no luck. I also
don't see this in the list of publication settings when defining a Book
Document. How do I control the height and width for PDF book pages?

Thanks,

Ted
