As others have said, you can get lines thinner than 1 point (1/72") by 
using the comment described in Tech Note 175.  This is the simplest way, 
if you know that you're printing on a PostScript printer.

A more general way is to use the PrGeneral commands to find out what 
drawing resolution the printer will support, then set the resolution and 
draw at, say 300 dots/inch on a LaserWriter or 216 dots/inch on an 
ImageWriter LQ.  Then if you set the pen width to 1x1 with QuickDraw, you 
will get a line 1/300" or 1/216" thick, as the case may be.

The PrGeneral call is described in a Tech Note, but I don't have the 
number on hand at this moment.
