postscript printing from emacs

postscript printing from emacs

[Stein Arild Strømme]

Hello,

I have the following problem printing with ps-print-buffer:  The
printer gives me one page containing only the letters "IB", and a
second page containing the following:

PCL XL error
       Subsystem:  KERNEL
       Error:      IllegalOperatorSequence
       Operator:   0x1b
       Position:   2

ps-print.el version 6.6.7, emacs 22.0.50.  Any idea what this is?  If
the postscript file is generated using ps-spool-buffer instead,
Ghostview is able to display the file correctly, but the same problems
occur if I try printing.  I have even moved the ps file to my Mac, and
Preview.app is not able to display it properly.  

I take all of this to point in the direction of ps-print.el.  Any idea
how this can be fixed?  If an expert in postscript code wants to look
at the code, an example can be found on www.math.uib.no/stromme/psfil
(based on a buffer containing only the single letter "a").

As alternatives, I'm exploring ways to use a2ps or enscript instead,
but they don't seem to support utf-8.  Other ways?

Grateful for advice.  We need only very basic printing.  

(lpr-buffer itself chokes on non-ascii characters; this may be due to
a complex printing environment at my institution, where there is a
Windows print server.)

Your printer interprets the incoming stream as some PCL – teach it to  
accept PostScript!

Use htmlize to convert the buffer or region content to UTF-8 encoded  
HTML, view it in a capable browser, print from the browser.

Well, all other postscript than the one generated by ps-print.el is
recognized and treated correctly.  That includes using a2ps og
enscript in various ways from within emacs.  I also find it suspicious
that Preview.app in OS X cannot display the file correctly (it does
with other postscript files).

So what is it about the ps-print-generated postscript files fools the
printer and Preview.app, that's the question.

That is tongue-in-cheek, surely?

I reported this error before. Ps-print is pretty useless, in any case  
in Mac OS X. Besides this it only supports one or two encodings: US 7- 
bit ASCII and ISO 8859-1.

 From the failure with Preview you can deduce that the Mac OS X and  
CUPS related mechanisms to prepare the PS output for printing are the  
reason that your printer reports a failure. It's nothing but non- 
sense that gets into the printer queue. (You can halt the queue and  
inspect what's in it!)

I presume it's like MSIE "optimised" web sites: only Ghostscript can  
convert and only Ghostscript can display. So the function family  
should better, before release of GNU Emacs 22.1, be renamed gs-print.  
BTW, the PDF output gs 8.54 produces from ps-print output on my Mac  
(Mac OS X 10.4.9) cannot be displayed in Preview, either.

No. It's a proven way. And it's the only way a few members on this  
list could find. The (Japanese) Carbon Emacs (Package) uses such a  
conversion and then uses an adapted version of the Coral application  
to convert HTML to PDF. You can try to use Apple's /System/Library/ 
Printers/Libraries/convert – it is meant to prepare or produce  
printer queue material.

Lennart Borgman has written htmlize-view.el to ease the conversion of  
buffer or region contents to HTML, and view it in your default  
browser. Then press Print ...


The problem with PostScript is that it usually only supports 8 bit  
encodings. So you can't print Unicode. You can try to find a CID  
keyed PostScript font and with some effort you can print CJK. No such  
font is available for free or public domain. TrueType and OpenType  
fonts have better Unicode support. Modern PostScript can use such  
TrueType fonts, which are quite often free and acceptable quality.  
But I have no idea how to create a mapping from an UTF-8 encoded text  
to a Unicode encoded font in PostScript.

I should have stated more about my situation: I'm running Linux in a
centralized university environment.  Printing is via a cups server
which in turn talks to a Windows print server common for the whole
university.  My mention of Mac OS X is peripheral to the issue, it was
just a test naively trying to narrow down the search for the culprit.
Involving a Mac is no solution in any case.

Unfortunately, I have absolutely no control of the queue at all.

OK, but both a2ps and enscript *do* work, in so far as the buffers get
printed, and even correctly, if encoded in 8859-1.  ps-print gives
nothing, even on the simplest of buffers.

OK, I have no doubts that it works, but it is too cumbersome.  

I suppose it is a luxury problem for me, I don't *really* need utf-8
(I can get by with 8859-1), I simply want to try to migrate to utf-8.
What you are saying below about postscript and utf-8 gives me second
thoughts indeed.

It seems that I have two distinct problems: 1) ps-print does not work
at all, even for straight ascii, and 2) nothing simpler than your
solution works for utf-8 encoded files.

I'd still like to understand 1) better.

If you try htmlize-view.el and tell me what you find too much work I 
will be glad to change it if it is possible.

Where can I find it?  Googling gets me some pages but some of those
download links don't quite work.  I'd like to try.  Perhaps it is more
convenient than I thought on a careless first reading..

Why not just post it here, onto this thread?

Sounds pretty neat, useful to lots of people here.

Turns out that there is a problem in Emacs 21.4 (Fedora Core release 5
distribution, started with -q option).  I get the following backtrace:

In current CVS Emacs (22.0.50) everything works OK, but I cannot get the

BS, Ghostscript produces standard Postscript files.

Don't know about Preview.app, the pdf files produced works in Acrobat

Don't know about Mac OS X. However, I can print to my HP PCL printer
with ps-print and yes, I am using Cups (I am on Linux).
