Files included in this archive
======================================================================
If you did not get this file as part of an archive, then you may
need to get the file PPST32.ZIP from the simtel mirrors in the
postscript directory. You should have gotten this file (README.32),
the results file (PPST32.RES) and the actual program file (PPST32.PS).

Please feel free to distribute this program in any form you wish
(CDROM, DISK, BBS, FTP, Modem, etc...) as long as you do not remove
any part of the archive. Please try to keep all three files together
as an archive (ZIP, ZOO, PAK, UC2, etc...). I do not give permission
for use of any part of this code in an other PS program unless
explicit permission is given by me to you for the specific project
that you would contact me about. (permission is valid only for that
instance, if you want to include part of this in any other project
please ask again). I am a very easy going guy, I just want to know
what people are doing with my program!

How to use the PostScript Processing Speed Test (PPST)
======================================================================
The simplest way of using this PostScript program is to simply
send it to a PostScript printer to have the printer execute it.
This will render a page output including the results of the test
which give the relative speed of the tested printer and an Apple
LaserWriter.
From DOS, you can type the command:
COPY ppst32.ps lpt1
-OR-
PRINT ppst32.ps
-OR-
TYPE ppst32.ps >lpt1
Replace lpt1 with whatever port is appropriate (LPT2, COM1) and
you must issue a MODE command to set the baud rate if you are using
a serial port (COMx).
You musn't load the file in a wordprocessor (like WordPerfect) and
then print it because that will simply print the words in the file
instead of executing it.

History
==========================================================================
The idea first came in June 1991 when I started learning the
Adobe PostScript printer language. I though that it would be
interesting to know how long it took for the printer to do a
particular job. I wrote a small graphics program including the
timing logic and thus was born version 1.0 of PPST. (I didn't
name it that yet though).
Considering all that, I though it would be interesting to have
some sort of relative test similar to Norton's SI for the PC or
LAN Mark, but for a PostScript printer. Since there are so many
different things that control the speed at which a printer can
output a page, you can't just judge it by it's processor, amount
of memory, or engine speed. There's more to it than that, and I
wanted to find out. This is when I wrote the first real PostScript
Processing Speed Test. I called it version 2.0 based on the fact
that it wasn't really the first one, as stated above.
Once that was out, I started getting comments on the code and
modified it so that it was a bit more meaningfull. By mistake, a
bad version was released, version 2.1, which will not harm your
printer, but will not give proper results. This is Why I jumped to
version 3.0. Version 3.0 only gave the relative speed of the tested
printer relative to an Apple LaserWriter.
After finally getting the numbers for the Apple LaserWriter II
NTX and the QMS PS-2000, I released version 3.1 in January 1992. I
started getting many replies from people all over the world, bugs,
problems and suggestions for improvement. During this time I had
a lot less time to work on this, so I didn't work on it until a lot
latter. There was a range problem with the graphics test because the
Adobe deffinition of the printable area is infinte and most printers
implement that, but some do not and those errors poped-up, an example
is the QMS 410. Although this problem is not critical, there was some
concern expressed by owners of these printers and from their
manufacturers. Also, when PostScript release 2 came out, the format
for the version number was changed and if PPST31 is run on any Level
2 capable printer, then the number will overlap the word "number".
After all that time, I finally decided to work on version 3.2a.
This version is mainlly a revision for the "features" of the printers
giving errors and to correct the printing of level two numbers. The
change in the tests is sufficient enough to make version 3.1 numbers
different, so I have had to wait until I got the results from an
Apple LaserWriter before giving index values (I did not have access
to one anymore). One I had that, I release version 3.2b (for beta) to
make sure that there wasn't any new bugs that crept into it. After
almost a month and only one "bug" report, I have decide to release
version 3.2 which is this version. The index results includes an
"image" result marked "next ver" because I had planed to include it
in 3.2, but ran into a snag. If you have any ideas as to how to
include a bitmap image test, let me know.
Well, there you go, enjoy!

==========================================================================
I would like to here from you about this program. Please let
me know of any bugs, problems with your printer or fixes that you
would recommend. I am always open to new ideas. A future release
will include a few of the more popular printers with a relative
index comparing your printer to them, but I need your input.
Please send info including the manufacturer of the printer, the
model number and/or name, and the results from this test. I would
also appreciate getting your name and e-mail (or regular) address
and/or phone so that I can reach you should it be necessary. I would
also be interested in knowing your occupation and interest in this
matter.
Thanking you for your replies

Included in the ZIP file are these files:
1) PPST32.PS ... PostScript Processing Speed Test version
3.2. Last updated March 9th, 1994. This test, when executed by a
PostScript printer will give relative speeds of this printer
compared to the Apple LaserWriter.
2) README.32 ... This file.
3) PPST32.RES ... The result of this test on various PostScript
devices. Please help me add to this list.
