orthlieb@adobe.COM (Carl Orthlieb) (08/21/90)
I have seen a few items come by on the net that seem to crop up from time to time. It has been suggested that Adobe periodically post a 'Frequently Asked Questions' (FAQ) article so that new users of PostScript can get answers to these questions. Being the current voice of Adobe, I think this is a good idea, and wanted to know if anybody had ideas of what would be appropriate topics that this article would cover. Ideas so far: What is Encapsulated PostScript? How to use Adobe's file server What is PostScript Level 2? What are the Document Structuring Conventions? What are Adobe Font Metrics? Any other ideas? Email to me at orthlieb@adobe.com, I'll put it all together and come up with the FAQ article. Thanks, Carl 8-)
nol2321@dsacg4.dsac.dla.mil (Jim Dunn) (08/21/90)
FAQ for PostScript Questions, eh? Great idea! How about someone giving us some idea of the various software/hardware requirements for printing PostScript. For instance... Scenario #1 No software and no hardware. What would be the most cost effective solution to PostScript printing? Scenario #2 WordPerfect or PcWrite or ??? and HP LaserJet or DeskJet. What would be the best/fastest way of printing PostScript? Scenario #3 Softfonts, hardfonts, conversion software, etc. Which is the easiest to handle, most cost effective... MOST FONT for the BUCK! :) I'm most concerned about information concerning "translation" of PS files into HP PCL language. I.e. GoScript, UltraScript, GhostScript, PSMAGIC, whatever... But the article that PcMag had a while back showed performance ratings WITHOUT A 80X87 COPROCESSOR!!! I've heard it rumored that with a 80x87 and a couple of megs of memory you can get a 90 minute Apple LaserWriter document in 90 SECONDS using GoScript, etc. This is EXTREMELY important due to the fact that I don't need to waste my $$$ on memory for the printer IF I can buy memory AND a 80x87 chip for my CPU which can ALSO BE USED WITH OTHER SOFTWARE!!! Please; let's get some REAL statistics; I know that Adobe Inc may not be the correct person to talk/yell/ask, but hopefully SOMEONE will be able to... (if no one else, I would be happy to collect info/create a demo/sample postscript file for timed printing use) Please reply netters! Jim jdunn@dsac.dla.mil

nol2321@dsacg4.dsac.dla.mil (Jim Dunn) wrote about the proposed FAQ list. (In passing - Jim: your article has a badly-broken header line; you're getting your email address into the Followup-To: line.) Jim's questions are things like "what's the most cost-effective...?" or "which app [or printer] should I use?" or "which is the easiest...?" Questions like these are interesting and important, but it's hard to package up canned answers because (1) they're subjective and (2) they're always changing. In fact, I'd say they more properly make up the substance of the actual discussion in the group. FAQ is typically to handle the stuff that doesn't need to be discussed much; it has "pat" answers. There are examples in Carl Orthlieb's article--a typical one is "What is encapsulated PostScript?" It's a common question and it has a relatively simple answer that's not subject to much debate...so we don't need ten variants of the answer posted every time someone asks it. In other words, FAQ is a way to offload the stuff the regular readers know so that the discussion can focus on things under contention. Also, it's a good idea to keep seriously debatable stuff out of FAQ because otherwise a bi-monthly posting generates a bi-monthly rehash of the same discussions and flames. I'm not trying to discourage the subjects Jim mentioned. Quite the contrary; I think his issues deserve active discussion instead of the passive place in FAQ. -- Dick Dunn rcd@ico.isc.com -or- ico!rcd Boulder, CO (303)449-2870 ...Are you making this up as you go along?

================================================================
What is EPS?
How do I convert PS to EPS?
EPS (Encapsulated PostScript) is a PostScript language program
that is limited to a subset of the language suitable for
inclusion in a document as an illustration.
In order to meet this requirement, the program must leave the
interpreter in the same state it was in at the program's
beginning (ie. all stacks returned to their original contents,
the graphics state back where it was, and any memory (VM)
consumed by the program has been released). The EPS program
must not use operators that initialize or permanently change
the state of the machine. As a special case, the EPS program
may use the showpage operator. The importing application is
responsible for disabling the normal effects of showpage. Note
that only one call to showpage may appear in the program (ie.
the program generates one page of output).
The EPS program should make no environment-sensitive decisions
(the importing application may be trying to attain some special
effect, and the EPS program shouldn't screw this up), although
it can use some device-dependent tricks to improve appearance
such as a snap-to-pixel algorithm.
Additionally, the program must have an identifying comment at
the top indicating that it is a conforming program, and a
comment specifying the region on the page that is changed (the
"BoundingBox" comment).
The complete EPS specification is available from Adobe (see
below).
A variation of EPS embeds the PS text in a binary file which
contains a header and either a TIFF or MetaFile preview image.
The header defines where in the file each section (EPS, TIFF,
or MetaFile) starts and ends. On the Macintosh, the preview
is stored as a PICT in the file's resource fork.
To convert from PS to EPS, one must guarantee that the PS file
meets the above requirements. If the actual program conforms
to the programming requirements, then one can simply add the
required comments at the top of the file saying that the file
is EPS and giving its BoundingBox dimensions.

How can I convert [other graphics format] to PS?
How can I display PS on my [brand x] computer?
Since PostScript is not just a picture-description language,
but in fact a complete programming language, one needs a
complete PostScript interpreter to convert or display a
PostScript graphic. Adobe PostScript interpreters are available
for some machines (notably those using the NextStep GUI).
Numerous PostScript interpreter clones, both commercial and
free, are available for other machines. Not all clone
interpreters know how to handle Adobe's encrypted Type 1 fonts,
and some have other incompatibilities. Clone interpreters will
not have Adobe's proprietary rendering technology which
interprets font hints to improve the appearance of fonts shown
at small sizes on low-resolution devices.
Ghostscript, a freeware product associated with the GNU
project, is available for PC's, Sun's, X servers, and other
architectures. Source is included. For more information about
Ghostscript, read the gnu.ghostscript newsgroup, or contact the
author at ghost@aladdin.com (L. Peter Deutsch).
Sun Open Look users can use Sun's NeWs or a new Sun Sparc-based
interpreter for driving non-PostScript printers (I forget the
product name).
MSDOS users can use Go-Script, QMS UltraScript-PC, or Freedom
of the Press. File format conversion is available with
Hijack-PS.
================================================================
What documentation is available on the PostScript language?
Adobe has written numerous manuals, sometimes referred to
by PostScript gurus by the color of the cover. These books
are published by Addison-Wesley. They are listed here in
order of (my) suggested reading:
PostScript Language Tutorial and Cookbook ("The Blue Book")
PostScript Language Reference ("The Red Book")
PostScript Language Program Design ("The Green Book")
Adobe Type 1 Font Format ("The Black Book")
Books published outside of Adobe include:
Real World PostScript ("The Orange Book")
Inside PostScript ("The White Book")
Thinking in PostScript
A new edition of the red book is scheduled to be released about
December 1990 which will incorporate features of Display
PostScript, advanced color handling, and new features added to
the language since the first edition.

Close, but not quite right. It is the importing application's responsibility to enclose the graphic in save/restore, so all memory doesn't have to be released and the graphics state doesn't have to be restored. But the program should not (for instance) leave any recent strings on the stack because that would cause an invalid restore . . . -tom

What is EPS?
How do I convert PS to EPS?
An Encapsulated PostScript file (EPSF) is a standard format for
importing and exporting PostScript language files in all
environments. It is usually a single page PostScript language
program that describes an illustration. The purpose of the EPS
file is to be included as an illustration in other PostScript
language page descriptions. The EPS file can contain any
combination of text, graphics, and images. An EPS file is the
same as any other PostScript language page description, with
some restrictions.
An EPS file must be a conforming file, that is, it must conform
to the document structuring conventions (DSC). At a minimum,
it must include a header comment, %!PS-Adobe-3.0 EPSF-3.0, and
a bounding box comment, %%BoundingBox: llx lly urx ury, that
describes the bounds of the illustration.
The EPS program must not use operators that initialize or
permanently change the state of the machine in a manner that
cannot be undone by the enclosing application's use of save and
restore (eg. the operators starting with "init" like
initgraphics). As a special case, the EPS program may use the
showpage operator. The importing application is responsible
for disabling the normal effects of showpage.
The EPS program should make no environment-sensitive decisions
(the importing application may be trying to attain some special
effect, and the EPS program shouldn't screw this up), although

Should I leave my printer on?
How do I suppress the power-on start page?
How do I remove a persistent ("permanent") downloaded font?
How do I reset the printer without power-cycling?
The general consensus seems to be that most computer equipment
lasts longer if left on. This presents less thermal stress to
the components. Disabling the start page is described in your
printer's PostScript supplement. The most common sequence is
"serverdict begin 0 exitserver statusdict begin false
dostartpage end".
One trick for removing a persistent font (this requires that
you knew you would need to remove it before you downloaded it)
is to issue a "serverdict begin 0 exitserver /magic-cookie save
def" before downloading and sending "serverdict begin 0
exitserver magic-cookie restore" when you want to reclaim all
VM used since the first download. The downside of this is that
is uses up a save level, but this is usually not a problem.
Most printers can be reset by issuing "serverdict begin 0
exitserver systemdict /quit get exec".

How do I get the physical size of a page?
The initial clipping path gives you the size of the imagable
area. Use "clippath pathbbox" to get these coordinates. If you
*must* know the size of the device's imageable area, use the
sequence "gsave initclip clippath pathbbox grestore", but this
will prevent an enclosing application from using the clippath
to achieve some special effects (such as multiple pages per
page).
