NB this message is not directly related to firewalls, but it may be useful
given the widespread (international) dissemination of documents in
PostScript form. Please do not reply to this on the firewalls list.

  The white paper is in word for windows format or postscript.

I don't have a way of reading W4W docs so I downloaded the PS version and
came across two problems. Secondly that page numbers in Table of Contents
are wrong 8-), eg Summary is on page 11. More importantly I couldn't print
the document and it took 15 minutes to figure out the problem. It seems
that the error-handler at the start of the document uses the neat Policy
feature of level-2 PS to specifically require US-sized paper. The rest of
the World, save Yemen I think, prefers metric paper sizes 8-). Luckily PS
formatted for USLetter-size will usually print on A4 paper without clipping
and there are at least two kludgy work-arounds:

1) if you've got something like Apple's LW630, the optional 500 page
paper-cassette allows manual setting of the paper-sense codes. You can
simply lie to the printer and dial-up US-Letter size.

2) there are two instances of [612 792] in the PS. Replace these numbers
with those for your paper size. For A4 that is [595 842].


While I haven't done this, if I was preparing PostScript on my Mac for
widespread distribution I would use the new LaserWriter 8.1.1 driver with
my printer Setup as Generic. I would select Save as PostScript Job, without
any of the basic 13 fonts to be downloaded. Without experience I still
wouldn't be surprised if some people had problems with the resultant file -
eg TrueType fonts or quirky embedded graphics. I don't know what the
equivalent conservative approach is under Windows or on UN*X platforms.


cheers,

PS and after sorting that problem out, I found the PS wouldn't print out
correctly with the 2-up prolog I use. I had to use a photocopier to do my
2-up version.
