We are running Unix 4.2 bsd on a Vax11/750 connected to an LA100 (Letter-
printer 100 -- Digital Electronic Corporation) and we'd like to get 'troff' to
work on it. Therefore, I'd like to pose the following questions:
(1) What does 'troff' output? I have been told it is CAT pho-
tosetter codes; what are CAT photosetter codes and where can
I find more information about them?
(2) I have been told that by piping 'troff' through
/usr/lib/vcat and /usr/lib/rvcat the output is converted to
a raster of bits. What does this mean and what do these
programmes do?
(3) Finally, assuming that I have all the information needed,
how do I go about getting it to work on a particular printer
(i.e. the LA100). I have the escape sequence that puts the
LA100 in graphics mode and I know how the graphics mode
works (in addition to knowing the specifications -- e.g.
dots per inch horizontally and vertically).
I shall endeavour to post a summary of the responses I receive in about a
month's time.
