I created a document on an 11" x 17" sheet.

The vast portion of the document was divided into three
columns in table format.

Columns two and three have text in them.  Column one was
split into smaller tables for information.

The header is in table format and it has two .jpgs in the
header (logos).

After creating the document, it looks fine on print
preview.  However, if I close the document, when I open
it again, while none of the document seems changed in
normal view, the entirety of the left-side of the page
(equivalent of column one) cannot be seen on print
preview or printed out.

WHAT IS ALTERING THE PRINT PREVIEW?
WHAT IS OBSTRUCTING THE VIEW OF THE LEFT 1/3 OF THE PAGE?
