Can you make ditroff print in landscape orientation on an Apple laserwriter?

[Michael Herman]

I have a tbl table that is too wide to print using in a standard
portrait orientation on a laserwriter BUT it would fit if I could 
use a landscape orientation.

The tools are have at hand are:
    - ditroff, tbl and -ms
    - Adobe Transcript
    - an Apple LaserWriter Plus

The ideal solution would be something like:
    - set *these* troff registers to *these* values
    - set *these* -ms registers to *these* values
    - use *these* options when you run *these* Transcript programs

... but I am interested in hearing about any solution that might work.
