It is simple to have your entire document printed in landscape mode.
Simply adjust margins to compensate for the new size of the page:

	\setlength{\topmargin}{0in}
	\setlength{\oddsidemargin}{0in}
	\setlength{\evensidemargin}{0in}
	\setlength{\oddsidemargin}{0in}
	\setlength{\textwidth}{9in}
	\setlength{\textheight}{6.5in}

The above should give you 1 inch margins all the way around.

Do everything else as you normallly would, but when you print it out,
you should to add "-o landscape" to the dvi2ps command.

	dvi2ps -t landscpape -Pprintername socrates.dvi 

Rotating a part of the document only is a little more complicated.

1. Copy the  rotcapt.sty file from  /mit/consult/lib/tex/macros
   and the   rotate.sty  file from  /mit/consult/lib/tex/macros to the
   directory where your LaTeX files are.  For example:

	attach consult
	cp /mit/consult/lib/tex/macros/rotate.sty ~/
	cp /mit/consult/lib/tex/macros/rotcapt.sty ~/


2. Insert   rotcapt   into your list of style options.

  e.g.
        \documentstyle[12pt,rotcapt,fullpage]{article}


3. Use the \rotate command to rotate the table or figure you want
   rotated. e.g.

	\rotate{
	\begin{tabular}{|r|l|} \hline
	1 & 2\\ \hline
	3& 4\\ \hline
 	\end{tabular}}

or

	\rotate{\PSbox{acid.ps}{8in}{4in}}

If you wish to center the box on the page, use the \centerline command:

	\centerline{
	\rotate{
	\begin{tabular}{|r|l|} \hline
	1 & 2\\ \hline
	3& 4\\ \hline
	\end{tabular}}
	}

4. For a caption in a table or figure environment that is rotated use the
   \rcaption command instead of \caption.  This will put the caption at
   the right hand side (or bottom) of the page.

   \rcaption takes 2 arguments: the caption and the width of the caption.
   The width should be same as the width of the table or figure. e.g.

	\rcaption{17 angels dancing on the head of a pin.}{5in}

5. To print the document out use the dvips command. Here's a typical usage:

	dvips angels.dvi -Pprintername

You can type:

	man dvips
