Using the papersize.tmac I sent. You can have different page sizes within the 
pdf, by stacking grout files:-

Using this example:-

.  if d paper-\*[paper-p]-length \{\
.    ie '\*[paper-l]'l' \{\
.      sp |(p;\*[paper-\*[paper-p]-width]/2u)p
.    \}
.    el \{\
.      if '\*[paper-l]'' \{\
.        sp |(p;\*[paper-\*[paper-p]-length]/2u)p
.      \}
.    \}
.  \}
.ps 24
.ce
Using page size \*[paper-p]\*[paper-l]

And these commands:-

groff -Tpdf -dpaper=a4 paper.t -Z > a4.Z
groff -Tpdf -dpaper=a4l paper.t -Z > a4l.Z
groff -Tpdf -dpaper=letter paper.t -Z > letter.Z
groff -Tpdf -dpaper=a5l paper.t -Z > a5l.Z
gropdf a4.Z a4l.Z letter.Z a5l.Z > Display.pdf

You end up with a 4 page pdf each page a different size/orientation. This is 
not particularly useful if you are intending to print the document, but the 
majority of pdfs are created for viewing.

The result is more noticeable in the pdf viewer if you turn off auto zoom 
(i.e. fit width) and set it to 100%.

Of course, you can achieve similar in one run by using the \X'papersize=' 
command within your troff file, which would be useful if you have a wide table 
you want presented in landscape, but you have to adjust page length/width 
yourself to notify the troff formatter of the changed dimensions.
