So you have just finished that Field's-Medal-winning work and are ready to
type it up (practically) mistake-free. Now you want to see
it printed out on paper. This is
done with the laser command. Assuming that you have a
mistake-free version of mythesis.tex and have used 
to create
mythesis.dvi, typing
laser mythesis
mythesis on a laser printer (probably
lw2, the HP laserwriter in the fifth floor lounge area).
Note that the laser command does accept preferences.
For example, if you wanted to print the first
five pages of your document on the fourth floor public printer, you
could type
laser -Plw8 -page1-5 mythesis
When you have printed a clean final draft, photocopy it for more copies. Do not laser-print it again.
