hello, I am looking for [nt]roff macros (-man -ms -mm -me) for the Xerox XP-24
laser printer. please e-mail

thanx in advance

Macros are *not* specific for a particular laser printer.

Nroff output is translated by specific tables in /usr/lib/nterm

Otroff writes CAT output which must be translated by a specific
cat2xxx filter

Ditroff writes DiTroff output which must be translated by a dit2xxx
filter.

Adobe sells filters for postscript that are part of Transcript.
Perhaps you should contact Xerox about filters for your work.

Unless I am missing something here (after a few years use of these packages
and nroff and troff), the macro packages are NOT printer specific.  The
nroff program is designed for impact type printers, ie, dot matrix and
letter quality (daisy wheel, whatever) constant spaced characters.  The
troff program was initially programmed for the C/A/T phototypesetter, so
the stuff coming out of it if very specific to the printer.  Now there is
ditroff, which is device independent troff.  We don't have that here yet,
though we will soon.  With troff or ditroff, you need a post-processor to
massage the output to make it work with particular printers.  Adobe Systems
makes the Transcript program to take troff (ptroff) and ditroff (psroff)
output and convert it to PostScript, for those kinds of printers.

So, as I said, the macro package is device independent.  You need to spruce
up your troff program's output.  Nroff cannot be used with proportional
spaced laser printers, especially PostScript.

A little too strong here! We have done this for years using PS fonts
on the Xerox 2700. It is tedious to set up the character table and
needs a post-filter (at least the way I did it) but it certainly
works.

I suppose I should have added as designed, nroff wasn't mean't for any printer
except those that I mentioned.  If anyone works hard enough at something,
one can get nroff output to work.

But, if one is going to work at nroff, it would have been better to work
with troff as it likes to work with proportional spaced fonts and variable
vertical spacing.  I don't understand why you picked on nroff, verses troff.
The only thing I can think of is that nroff outputs ASCII characters and troff
the C/A/T phototypsetter garbage.

As others have said, troff should be pretty much independent of macros.
The only case that special macros need to be used is with 4.x troff.  In
this case, one needs to re-mount the standard fonts to get troff to read
the font metrics from disk.  That's only a four line file.

As an aside, the name XP-24 doesn't say very much because "XP-24" is just the
name of the marking device.  It accepts a video-like interface puts marks on
paper.  If you want to use it from a computer, a controller must be added to
determine how it will behave.  For example, the XP-24 can be packaged
with a certain controller to produce the Xerox 3700.  With a much
different controller, it is the Xerox 3700+ (which, despite the similarity
in name, does very different things).
