Sorry if you have already red this article, but I think that the first
one got lost.

I am writing a report and I am including some hardcopies of a
Lisp Machine screen (Postscript format) in it. To avoid any
cutting/pasting, I include the "postscript file" in my document (using
the \special command with LaTeX/dvips).

Unfortunately, each screen dump is approximately 220 K... Considering
that I will have 60 screen dumps... It makes 12 Mega of pictures for
this report... (that I have to keep under postscript format for
inclusion)

I had a quick look to the format used in this screen dump, and it looks
like it is not compressed at all. When I run it thru "compress" I get a
91.08% compression rate (after all, these screens are almost white).

I was just wondering if anybody have already written, in lisp for
the Lisp Machine side, and in postscript for the printer side, a
small"compressor".  

Thanks in advance,
