There are special printer drivers fom adobe just for generating 
postscript.
Actually you canīt use these drivers to directly print on a printer, 
but to
generate postscript files. And this postscript code should be extremly
correct, because thats the only sense of the drivers.
Take a look at it.

I assume you talk about ACL on windows (from the other question). I 
dont
know anything about graphics on UNIX.
 
For a first and very easy approach to the problem I would use the 
printing
capabilities of Allegro. The printer is a stream which works like a 
graphics
device in MS Windows. You can use it almost like a window. And you 
install a
printer driver for a postscript printer and connect it to a file. From 
my
experience of generating "good" postscript from MS Word, I recommend 
using
the Apple LaserWriter II printer driver. These printers are bit old, 
but
printers and drivers were famous for having excellent postscript 
(almost as
good as dvips). "Good" postscript in the meaning of "well formed and 
valid"
postscript, which means you can use it later on anything which claims 
to be
able to handle postscript.

I've seen this several times myself. This does not happen in Windows 
NT. I
would recommend to set the optimization flags in ACL to some minimal 
values
(not to (speed 3) (debug 0) ) and stay away from anything like
without-interrupts. Things on Win98 get worse if you're using threads.

Hi,
  I'm probably dreaming, but is there any possibility for easily 
generating
postscript (or other common formats) from a standard Allegro graphics
session?
  In short, is there any way for me to run my normal graphics code and 
just
send everything to a special type of stream (e.g. for a postscript 
file)
instead of my normal window stream?  
  Basically, I draw a lot of different types of diagrams in Allegro, 
and
it's kind of a pain to have to dump the data to files and then redraw 
them
in another language (like MATLAB) to get nice print-outs.
  I'm using Allegro 5.01 or thereabouts.
 
One other question:
 
I've asked this several times, but the suggested solution never works:
 
  When running Allegro in Windows 98, I can't find a way to break my 
run
without terminating Allegro itself.  This has become a real pain 
recently,
since I'm debugging some pretty hairy code which frequently goes into
hyperspace.  I have no problem halting stuff in Unix, but in Windows, 
the
usual use of the Break key just isn't enough.  I have to do 
cntl-alt-break
to get any interrupt, and then my only option is to kill lisp itself.
 
Cheers...
