[Postscript] Emitting Postscript from REBOL

on windows you need to use gdi
on osx i guess you need to create a pdf

Doesn't OSX have a postscript interpreter in it ?
Henrik

OSX uses LPR, I think
Graham

Or did that change?
Gabriele

henrik, does it take ps too?
Pekr

I think we don't have many choices - you can to-image your layout, 
or go for external engines, using some make-docs - pdf, postscript, 
html plus css standard ...

postscript works on a different level. it's OS wide in OSX. I think 
it converts everything to PDF before printing, because all graphics 
are PDF centric.

if windows handled ps i guess we'd have a good solution. it would 
have been easier for me to write a ps maker instead of a pdf maker 
:)

gabriele, I would think it does. I have to convert docs to PS if 
I want them printed under Linux with LPR
Gabriele

lpr, per se, does not mandate a document format
it just spools documents to the printer
originally documents were text files
and, if you had a ps printer, ps files

how "good" is already w3c's stuff here? I mean html plus css and 
it's media (printing) capabilities? browsers are everywhere ....
Henrik

[935]
then I don't know what it does, but I can pipe PS files directly 
into LPR
Gabriele
26-Apr-2006
[936]
then, ghostscript got put in between lpr and the printer, so that 
you could always use ps even for non-ps printers
Graham

PS files are just text files
Pekr is very opposed to using ghostscript!
Gabriele

petr, i don't think it has ever been important for html to be a printing 
ml
Graham

I think early Netscape clients emitted PS as well.
Henrik
26-Apr-2006
[941]
well, if this is accurate, I don't use ghostscript at all. this 150$ 
printer here must be able to handle postscript natively then :-)
Gabriele

i mean, you can print an html document; but if you wanted to print 
a book, you wouldn't probably use html
Graham

some printers come with postscript emulation.
Gabriele, that's what annoys me about Rebol documentation.
It's all html and you can't print it.
Pekr

Gabriele - I know, but they try to ... Graham - yes, I try to use 
what is at user's disposal already .... browser or mostly Acrobat 
Reader ....
Graham

In the early days, rebol docs came as pdfs.
Gabriele
26-Apr-2006
[948]
that's one of the reason a pdf emitter for md3 is very important
Henrik

I think HTML/CSS is not good enough for printing, even with the printing 
oriented CSS commands. It's a nightmare to match margins, and browsers 
don't interpret the settings equally.
Gabriele

and why i studied TeX
Graham

I was most upset seeing images cut in half by my colour printer when 
printing out the view docs.
Pekr

[952]
yesterday I looked at two big printers here (not very skilled in 
that direction) and I found PCL, PJL, LPR you mentioned. What are 
PCL and PJL? Othere languages to support printing?
Graham
26-Apr-2006
[953]
TeX would have reshuffled the images around so that they wouldn't 
get cut in half.
Gabriele
26-Apr-2006
[954]
the problem is not html itself, it's that browsers are not good at 
printing
Graham

PCL is printer control language
from HP.
Its very escapist.
Gabriele

gotta go, later!
Graham

bye.
The problem with floating tables and images, is that if they don't 
fit in their entirety on the current page, you have to move them 
to the next page.

Gabriele - I know, browsers are just containers for other technologies. 
It will last at least one or two years, before browsers  (for most 
userbase) support  ajax, svg, css 3, etc., but they are actively 
developed and will always be at user's desktops .... there is also 
one czech product, called formfiller ( http://www.ff.cz), which 
allows (internally hopefully xml) docs.  xForms is the standard we 
should watch ...

Pekr, in your large organisation, are there really no postscript 
printers?
Pekr
26-Apr-2006
[963]
there are, most of them, but give me easy preview ....
Graham
26-Apr-2006
[964]
did you look at my two column preview ?
Pekr
26-Apr-2006
[965]
yes, slow at zooming, but working .... will you be able to get any 
ps complicated doc be previewed in your viewer?
Graham
26-Apr-2006
[966x2]
only if it is generated by the dialect.
Remember, this isn't a postscript viewer... but a viewer of a rebol 
dialect that can either output to postscript or to draw.
Pekr

[968x2]
so if you can do it in terms of your dialect, it is previewable? 
then it is absolutly sufficient imo ....
the good thing then will be, that I will be able to localise ti, 
or change its design, if it stays for free ....
