I assume Mr. Brown is using FOSI. Landscape orientation in Epic page
layout set means that the flowing text is rotated 90 degrees to the
header and footer.
Portrait orientation means that the header, footer and flowtext all have
the same orientation, but that the page dimensions are defined as being
wider than they are long.
It sounds like Mr. Brown has the second circumstance, but it also seems
like maybe he doesn't have a verso and and/or a blank (if required) page
model. This might cause it to reset to normal after one page. If the
wide page model is caused by the existence of an element, perhaps the
"local" or "global" properties for switching to the new page model could
affect this, or some other child element formatting could be switching
this back.
Also, he could try using the Acrobat Distiller or Adobe PDF (depending
on Adobe version) printer to see how a PDF file comes out. If it looks
OK, you can then print from PDF. Also, experimenting with an Adobe
printer would not kill as many trees.
