Both "\newpage" and "#+LATEX: \newpage" generate page breaks in Latex.
However "\newpage" is included verbatim in HTML export.
Should I use "#+LATEX: \newpage" instead?

This works well for me:
#+HTML: <div style="page-break-before: always"> </div>
placed right where you want the page break.
The break will not appear in the browser, but it will when you print.

That works. But that means I need both #+HTML: and #+Latex: for the same
thing. \newpage should convert as appropriate depending on the export.
So, \newpage should translate to the HTML equivalent on HTML export, and the
Latex equivalent on Latex export.
It only works correctly on Latex export

\newpage is a Latex command, and so you need the #+Latex: prefix if
you're exporting to multiple formats. That will prevent it from
happening.
You could use both the #+Latex newpage and the #+HTML snippet together
at the same point to have the same behavior in both modes.

To add a historical comment, eventhough Org claims to be backend
neutral, it treats LaTeX preferencially in practice. e.g. many common
LaTeX commands/macros are "understood" by Org.
Just follow what Russel said, put them both where you need a pagebreak.
Try this:
#+MACRO: pagebreak @@latex:\newpage@@ @@html:<div style="page-break-before: always"> </div>@@
{{{pagebreak}}}
Hope this helps,

Emacs already has the concept of the page-delimiter (defaults to ^L),
for page-related commands. I once floated the idea of making a
page-break a full org element, that could be handled differently by
different backends. I think I made it sound too complicated, though.
Anyway, that's still a possibility.

You are not alone.
The ODT model would be to create a Paragraph style with page-break
before or after. It is not a standalone element but a special type of
paragraph.
http://lists.gnu.org/archive/html/emacs-orgmode/2013-08/msg00568.html
I have introduced #+PAGEBREAK and also #+ATTR_ODT: :style "whatever" for
specifically this purpose.
> I think I made it sound too complicated, though.
It is difficult to argue with Nicolas.
He has written down a list of things he want to accomplish somewhere.
Unless your suggestion is a bug or contributes to his list, he is
unlikely to consider it.
> Anyway, that's still a possibility.
Ok. Ok.

Here's a fairly simple first stab, with page breaks made into an
element, and a sample handling in the LaTeX backend. I've hardcoded ^L
and the page-delimiter regexp that finds it, not sure it's worth
providing an org-page-delimiter shadow. For now, use C-q C-l to insert
the control character.
If this passes muster I can go through the other backends and add
page-break handling where it makes sense. If not, I'll just keep it on
my local branch!

Thanks for the patch.
Anyway, I don't think this is a good idea to introduce a new syntax just
to avoid a one-liner (or a hook, see below). Also, this would only make
sense in few export back-ends.
Really, introducing new syntax has a cost, so you have to ponder if it's
really useful, because, once installed, every Org user will have to pay
the price for it.
In the same vein, we have a couple of dubious syntactical elements which
probably sound great for a few users but don't make much sense in most
cases (e.g. quote sections, which can be replaced with an example(!)
block and comments blocks, which can be replaced with a regular
comment).
Admittedly, in this particular case, that cost isn't very high, but
I think it would nonetheless add up to the list of hardly-used syntax
category.

You don't need such a patch. For example, you can install the following:
(defun my-page-delimiter-hook (backend)
(while (re-search-forward page-delimiter nil t)
(replace-match
(cond
((org-export-derived-backend-p backend 'latex)
"#+LATEX: \\\\newpage")
((org-export-derived-backend-p backend 'html)
"#+HTML: <div style=\"page-break-before: always\"> </div>")
;; Ignore page delimiters in other back-ends.
(t "")))))
(add-hook 'org-export-before-parsing-hook 'my-page-delimiter-hook)
Obviously, you can handle as many back-ends as you see fit in
`my-page-delimiter-hook'.
Here are a few comments about the code:

Since `page-break' is an element type, you cannot make it also an object
type.
Also, you would need to update `org-element-paragraph-separate' regexp.

Using `page-delimiter' is not desirable because it implies that its
syntax is customizable, which would go against the last syntax patches
(changing defcustoms into defconsts whenever possible). Customizable
syntax cripples portability: please use it with care.

But is it really a new syntax or just support for an existing Emacs
convention? See (info "(emacs) Pages").
It seems like a feature which could be supported in many back-ends: LaTeX,
ODT, HTML, Texinfo, Ascii, Org, (Groff), maybe even md with pandoc.

No worries, I'm not terribly married to this, and I do think I do more
multiple-backend export than is the norm. I appreciate the code notes --
I'll admit I was a tiny bit confused about the difference between
element and object. I also wavered between making it a hard-coded
defconst or a fully customizable option, and landed awkwardly in
between.
A hook will probably do me.

I do not question this.
My point is that introducing this new syntax would bring up nothing that
can already be achieved using filters or hooks.
So, is this feature a must-have? Or would a filter template in Worg more
appropriate in this case?

It's not that everyone is desperate to have this in org proper. Putting
it into the code base vs making a hook: my guess is the number of LOC
would be very nearly exactly the same, and there's literally no
practical difference in the result. When "why" and "why not" are
perfectly balanced, it may be better to do nothing.
But I think it just *feels* right, because the page delimiter already
seems like a first-class citizen in emacs. I'll admit it's also
partially because it's a control character. Control character! Must be
serious programming. I also like the thought of a new org user sticking
one in their document, exporting, and finding that org does the right
thing.
At this point, I'm pretty much neutral buoyancy on the issue, though...

I (as a user, so not carrying the maintenance burden of any added
feature) am in favor of having this feature in org directly.
I think many people that use some of the export functionality will need
to control page breaks at some point. If this is not supported by org,
most of them will have (as I did until now) backend specific page breaks
in their org mode files (maybe multiple, as suggested earlier in this
thread), which is the inferior solution.
A possible argument against the filter solution is, that an org file that
relies on the presence of a filter is less portable.
And I do not agree with 'the number of LOC would be very nearly exactly
the same' as the filter has to be copy-pasted by every one who wants to
use it ;-)
So in short: If page breaks are not in org directly many people will
end up with inferior and/or less portable org files.

That, or showing how to make a {{{pagebreak}}} macro expanding to export
snippets. (And explaining how regular page breaks before new chapters
etc. are anyway better handled by styles in ODT and HTML-for-print.)

You could have used a #+PAGEBREAK and handled it as part of say an
advice to org-BACKEND-keyword in whatever BACKEND you are using.

For the record, after thinking about it, I'd rather stay away from
invisible characters in Org syntax, would it be page breaks or
non-breaking spaces.
Porting an Org file requires to also to port Org configuration. A filter
is enough to support these characters. Added support would just be, IMO,
"coolishness".

Just for me to understand:
The recommended way now is to have a filter and write (say) \mypersonalnewline
in my orgmode files? Even if \mypersonalnewline won't work for anyone
except myself? Or did I miss something?

You can write ^L in your files, as long as you transform it into
something useful, through a filter.
It will work for anyone with whom you share your Org configuration, or,
at least, anyone using an equivalent filter.

I am not interested in ^L in particular. I am interested in a
pagebreak, that works across backends. My filter will not use '^L' but
rather '\newpage'.

Ok. So be it.

FWIW I fully support not using invisible chars in Org syntax.

This follows up on just a side aspect in this thread that is (partly)
separate from its subject.
Just to wrap the thread up in my words:
1. Cross-backend (or more cross-backend) support of \newpage built into
Org directly was disapproved in favor of a less portable filter based
solution [fn:1].
2. Introducing invisible chars (as syntax for a possible implementation
of such cross backend \newpage) in Org syntax was generally
disapproved.

Andreas

Could you expand on what you mean by "less portable"? I'm interested in
portability from a reproducible research perspective and want to avoid
habits that don't port well to other researchers' systems.
Happy New Year!

I did not want to include these words in the first place. The words 'less
portable' are too strong here.
You won't be affected, since you ship your emacs / Org configuration
with the document, IIUC. (Which is the only possible way to achieve
something like reproducibility with Org...)
In that case you can simply include such a filter in that configuration.
The non-portable part comes from the need to share that filter.
Anybody without that filter will not be able to export your document in
the intended way.
Just to clarify:
It is a very small thing and I am very much happy with using a filter based
approach here.
> Happy New Year!
Same to you!
Regards,
Andreas

One thing really worth improving is the tutorials around filters on
Worg. Or maybe: let's create a place similar to org-hacks.org called
org-filters.org listing useful filters.
Any taker?

I agree. an org-filters collection would be awesome!

Not me, I am afraid, since I am completely out of time right now(so that
I should actually not read or write anything on this list...).
I am very sorry -- would have been a nice way to contribute.

No problem, I just wanted to verbalize this wish so that someone
with more time at hand can take the challenge :)

Shouldn't, then, some filters be available by default in core Org?

I don't think so: my understanding is that "default filters" would
then be implemented without relying on filters -- so filters are
really optional by nature. Nicolas will correct me if I'm wrong.
But building a page on Worg listing useful filters is a separate
task, and a good one.

The thing is that, IMHO, there are 2 types of filters required:
- filters for my own additions to Org syntax, that I don't need (or
want) to share with anybody
- filters for "missing" Org syntax which seems a need that many users
have at some point
The \newpage stuff, AFAIU, falls in the second category. This question
came a couple of times already on this ML, hence my suggestion to offer
it in a more standard way -- without just telling "go on Worg, copy some
snippet you'd find, paste it in your .emacs, and tell your colleagues to
do the same".
Best regards,
Seb

Yes, that's why I suggest filters to be only for local customizations,
while "filters-needed-by-many-users" should really be in the code (and
probably not as filters.)
But still, a place to find and learn about filters would be nice.

It already exists:
<http://orgmode.org/worg/exporters/filter-markup.html>
Maybe this can be improved?

This is the documentation for export filters, with some example.
But it is not clear that this page welcome new contributed
filters, and I think it does not.
I think having another page would help.
