Hi to all,
I want to print a PDF right from my python app transparently. With
"transparen tly" I mean that no matter what program handles the print
petition, the user shouldn't be noticed about it.
For example, when I want to print a PDF, Adobe Acrobat fires and keep
opened. This is what I don't want to happen (and I thing there are a
lot of people who want this too). So I just want to send the PDF to the
right handler and print it. That's all.
I've seen some things like Adobe's Postscript driver that can read a
PDF, or Ghostscript, but I still don't know how to use it.
Any help for printing a PDF transparently?
Thank you
Daniel

The only way I was able to find to do it (for free) was to install
GhostScript and GSView. GSView comes with GSPrint.exe, which you can
call with a regular command line to send PDF files to a printer. It
uses GhostScript for you behind the scenes because GhostScript is not
exactly the friendliest program to work with.

This works for me:
system("lpr whatever.pdf")
Or alternatively,
os.popen("lpr". "w").write(myBi gStringContaini ngPDF)

Hi, Thanks for all the answers.
My main purpose is to print on Windows systems (98,2000,XP) and permit
to print pages of 1/3 of a letter height, and make the printer to stop
at that point (in dot matrix printers). When I have a PDF with that
paper size and send it to print from Acrobat, it prints and stops
perfect (in Win98, I have to create a custom form consisting of that
paper size). The problem is that PDF files have to be handled by
external applications, or non-free drivers.
Based on all this, I have been investigating about postscript files. I
realize that printers do handle this language, so I think if I have a
..ps file and send it directly to the printer, it should do the job,
right? (this is certainly a question) If the answer is True, no matter
in what platform I am, if I send the same .ps to the printer, it should
print the same result.
And if all of these is true, then, my problem reduces to generate the
..ps file.
Comments please
Daniel

No. There are PostScript-Printers out there - but your off-the-shelf InkJet
isn't, and that's the reason why there usually has to be some sort of
driver in-between. Which is either GS or, in case of PDF, the acrobat-* or
any other PDF-printer-emulator.
maybe you can go down the rocky road of automation here, remote-controlling
acrobat reader. But I doubt that it wouldn't at least flash up with its
window for as long as the printing lasts.

Right. It's possible, barely, to achieve the desired result
with Ghostscript, but it's going to take considerable care in
installation and configuration. We do this sort of thing, but
only on hosts we control; the thought of full-blown "producti-
zation" (let alone the licensing) intimidates me.

You may find that RedMonEE is a useful piece to your puzzle. I find it
to be stable and quite invaluable.
http://www.is-foehr.de/ RedMon - Redirection Port Monitor EE
Transparent PostScript printing from Windows NT, W2K and XP. Overview
The RedMon EE port monitor redirects a special printer port to a
program. RedMon EE is commonly used with Ghostscript and a
non-PostScript printer to emulate a PostScript printer.
RedMon EE can be used with any program that accepts data on standard
input.
Using RedMon EE you create a redirected printer port. If you connect
a Windows printer driver to the redirected printer port, all data
sent to the redirected port will be forwarded by RedMon to the
standard input of a program. The output of this program can be sent
to different printer port, or the program can generate whatever
output it desires.
A PostScript Windows printer redirected to a RedMon port can shared
on a network. When this printer is configured to use Ghostscript and
a non-PostScript printer, it appears as a PostScript printer to other
network clients.
> Adobe has a Windows PostScript driver for free; but that still leaves you out... It works as a "printer" but you still have to run the
normal application to print /to/ it -- and that is what you say you
don't want! http://www.adobe.com/support/downloa...jsp?ftpID=1500
Yes, I've seen it, but that's it: another program that I have to
install, which I want to avoid.
I'd be happy if I just do "printer.Print( file.pdf/.ps)" and walá, the
printing just starts (in 98,2000,XP... sounds like a dream), without
having another window opened. If it opens, but then closes, it's
perfect too. I have tried installing Ghostscript, and having a .ps when
I order that file to print, it does the job. The thing here is that I
have to install it.
All this has to be easilly installed (with InnoSetup, for example),
because I have to install it on 70 offices. So I can't leave it to
another installation process. All of these offices have a dot matrix
printers Epson LX-300, which has PostScript level 3 built-in.
Where can I find how to send a .ps directly to the printer?

I have done such thing a few years back, just use the file association
and the "print/printto" action. All you need is to have Acrobat
installed. You can try it by right click on the desktop on a .PDF file
and select print. A modeless dialog would still be visible but would
close itself. This was using ancient Acrobat Reader.
You need to read the WIN32 API(I faintly remembered about Shell
something) that tells you how to do it programmaticall y(I used C).

Again, in the WIN32 API and unfortunately 98 and NT family has
completely different mechanism. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
