You can \shipout just a box containing the contents that you want.

For example, here's how you can do it with  pdfTeX
adding a frame for good measure.

%  put this in the preamble
\usepackage{graphicx}
\newbox\shipoutbox


%
%  wrap your content like this:
%
\setbox\shipoutbox=\hbox{%
    % <-----  put your contents here !!!
}%
\setbox0=\vbox{\kern-1truein
   \hbox{\kern-1truein
     \framebox{\box\shipoutbox}%  you don't really need the frame
   \kern1 truein}%
  \kern1truein}%
  \dimen0\ht0 \advance\dimen0\dp0
  \pdfpageheight\dimen0
  \pdfpagewidth\wd0
  \shipout\box0

Similar coding should work with XeTeX as it also
uses  \pdfpageheight  and  \pdfpagewidth .
