making ditroff dependant

[netnews]

     I am currently purchasing a hewlett packard laserjet (laser) printer
for the Computer Science Department here at Georgia.  There is a software
interface (for troff) available through a company called Elan in California,
but I was recently offered the source for ditroff and am curious to obtain any
background from anyone who would share with me about porting it to a 3b5 
machine or anything else running System V Unix.  Thanks in advance.
