  1. Buy a network enabled printer that supports PDF printing with some
    kind of upload support (e.g. FTP server)
  2. Buy an application that enables you to upload the file to it and
    thus add it to a queue and then send it to the printer, look around,
    there has to be such an application somewhere
  3. If you have no control over the enduser’s environment and since
    you’re dealing with a web application, it’s up to the user to either
    download the file or view it in the browser via a plugin and print it
    themselves. You can’t force the user’s browser to print the file.

Best regards

Where are you trying to print it? On the server or on the users PC?
It is not possible, I think, to force a print on the users PC from a
web app, the user must do that himself.

On the user’s PC you can use javascript to trigger the printing
(window.print) but, as Colin correctly notes, that will present the
user with a printer dialog box, not automatically print the contents
of the page. At any rate, that’s not relevant until you get the pdf
into the user’s browser. To do that you’ll probably use send_file
which, iirc, will trigger a dialog that asks the user whether they
want to save or print the file.

I think that would be browser-specific. Wouldn’t send_file just make
the browser act the same way it would when it received a static PDF
file?

Yes it would. And 1) you’re right - the options probably are
browser-specific, and 2) the options I was thinking of are save or
open, not save or print. And further, the javascript option wouldn’t
work either since the pdf would either replace what was in the window,
open a new one, or open the file in Reader. My bad. Responding
before caffeine kicks in is dangerous ;-(

Understood. Next time wait till before the caffeine kicks in before
posting to the list. :slight_smile:
