Questions about nroff/troff

[Roger Collins]

First, complaints:
When I have a table with double rules, only a single rule gets printed on 
a laser printer.  (The single rule is overstriked once.)  Also, the vertical 
lines do not meet exactly with the horizontal lines.  Tbl appears to produce 
output that says go up 1 point; draw single rule; go down 2 points and draw 
another single, thus producing the double rule.

My question:
Does nroff even TRY (given a complete /usr/lib/term/* table) to move, 
vertically or horizontally, points at a time?  Apparently not.

Another question:
Is there a way of defining a printer table for troff like /usr/lib/term/* is
to nroff?

My goal is to print fancy tables and fonts and stuff on a NCR 6416 laser
printer, preferably in the more powerful ISO mode, using tbl/eqn/nroff/troff,
and the output look more like a laser printer instead of a dumb line printer.
Is anyone doing this?  What are my alternatives?  Any public domain filters 
that replace troff?  I am running SysV.3.
