  I had the same problem on an 11/750 running Ultrix 1.2, even using neqn.
  The problem was an incorrect ternminal driving file. When I simply
  modified one that worked for another printer (say default) using the sequences
  out of the ln03 manual, it worked (except square root, posted elsewhere ...).
  I didn't analyze the original file too much, but it was either incorrect 
  syntax (though it compiled) or (I think more likely) the people at DEC put
  some crazy numbers in for `resolution' values.

  This stuff worked fine once I threw away the DEC supplied file. No col -f
  (or whatever) was needed, although it was passed directly to the laser 
  printer (no output filter ...).
