How can I print a portion of my document in landscape mode?

If you wish to print out a portion of your document (more than one page) in landscape mode, you'll have to do it in two or more passes.

1. When you want to switch into landscape mode, change the margins to correspond to the new page dimensions. For example:

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

If you need to switch back into portrait (normal) mode, just reset the margins back.

2. Latex the document as normal.

3. Print out the document as normal, except select only those pages that aren't in landscape mode.

4. Print out the document with the landscape option (-t landscape in dvips), selecting only those pages that are in landscape mode.

5. Combine the two printouts together into the the right order.
