+Print your stuff on Möbius bands!
+@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
+
+:slug: mobius-print
+:date: 2024-03-02 18:07
+:tags: lifehack, print
+:category: technology
+:keywords: Möbius band, two-sided printing,
+:lang: en
+:translation: false
+:status: published
+
+I found a fun and useful way of printing stuff to ~~both~~all sides of a paper.
+I just need to find the right printer!
+
+Quick recap: how to conventionally print stuff two-sided
+========================================================
+
+A typical way is just sending the page to get printed two-sided (with setting
+the correct way of flipping pages). That is, on the other side of page 1 is
+page 2, next sheet contains pages 3,4, then 5 & 6, …
+
+This is usually trivial to print on duplex printers, a bit hard to simulate on
+one-sided printers (but some drivers can do that) and has drawbacks when you
+need to look at stuff on other pages at the same time – you need to flip the
+sheet often, as you only can put half of the pairs of pages next to each other
+(even one and the following odd one).
+
+.. figure:: {static}/images/mobius-print/twoside.svg
+ :width: 66%
+
+ Ordinary two-sided printing. Red arrows show sheet flips between consecutive
+ pages.
+
+A slight improvement hack is putting two pages on the same side of the paper
+(works well with A-series of papers, I don't know for Letters &co.) – you can
+put up to four pages of the original document next to each other, if they are
+the right ones, but there are still pairs of pages that need turning sheets.
+Also only works if the original pages do not have too tiny features on them.
+[#illustrations]_
+
+Booklets are fun and approachable, but still suffer from the same issues as the
+conventional duplex print. They might be a bit hard to print, but programs like
+``pdfbook`` or ``paperjam`` make it easy to prepare for the classic duplex
+printing. Also, it is maybe hard to tell which page ends up where, as the order
+is: last+first, second+penultimate, third-from-end+third, … until the pages
+meet in the middle.
+
+.. figure:: {static}/images/mobius-print/booklet.svg
+ :width: 66%
+
+ The most common booklet order with two pages per side for landscape
+ orientation. (Note that we show more pages, and thus more sheet-flips; the
+ number of sheet-flips is in fact the same as for two-sided printing.)
+
+The improvement for seeing multiple consecutive pages
+=====================================================
+
+In order to be able to look simultaneously at many consecutive pages of the
+original, I think the order of first+first-past-half, second+second-past-half,
+… middle+last is much better (or maybe even the best). Since consecutive pages
+end up on different sheets (whenever there are at least three pages), if the
+original has e.g. figures on different page or long code listing, you can see
+it all!
+
+.. figure:: {static}/images/mobius-print/mobius.svg
+ :width: 66%
+
+ The "Möbius order" of pages.
+
+And this is really easy to use: You read a page and when you don't need it
+anymore, you flip it and put to the end of the page stack [#ordering]_. If you
+need to look at several pages, just rotate them in the same order as they go the
+first time. [#mistake]_
+
+Need to print this? For one-sided printers this is rather easy, too: just print
+the first half (the bigger one) on the sheets, then put them back into the tray
+and print the rest on them. You might need to experiment which side the sheets
+should be put in and whether you need to print the rest in reverse order, but
+that is it.
+
+Got the pages shuffled? Sort them by the first half, as if the print was
+one-sided.
+
+The only annoying thing for me is that there is not much software that could
+reorder the pages for two-sided printing, so that you don't need to re-insert
+the sheets back in the tray. So I `patched
+<{static}/images/mobius-print/interleave.patch>`__ `paperjam
+`__ to enable this. [#multi-mobius]_
+
+And the best part? If you would try to glue consecutive pages side-to-side,
+you'd end up with a Möbius band! So if you get a Möbius paper, you can just
+print this one-sided (duh :-D)
+
+Honorable mention: leporello
+============================
+
+Printing leporellos (aka concertina folded) also has many of the same benefits,
+since there is only one pair of consecutive pages that need a page flip. The
+order is first+last, second+penultimate, … and the original pages can be
+shuffled this way with ``paperjam`` or simply using the other order for the
+second side printing, than for the Möbius band. But there is a bit of fun
+topology missing here :-)
+
+.. figure:: {static}/images/mobius-print/leporello.svg
+ :width: 66%
+
+ A leporello order is also quite good, with only one sheet-flip in the entire
+ document.
+
+Is this the best order?
+=======================
+
+Yes, if "best" means "the minimum difference of numbers of pages that get put
+on the same sheet is as big as possible". The proof is left as an exercise for
+the reader.
+
+.. Hint: you cannot pair the middle page to anything else to get a better
+ result.
+
+Of course, this holds for a set of pages with no additional assumptions. In
+ordinary print, having a sheet-turn between chapters is fine and under similar
+guarantees other approaches may yield better results.
+
+Cheat sheet: paperjam commands
+==============================
+
+.. list-table:: Various commands for ordering pages for duplex printing with paperjam.
+ :header-rows: 1
+ :widths: auto
+
+ * - Order
+ - Command
+ * - Classic two-sided
+ - ``null``
+ * - Two pages per side
+ - ``nup(2)``
+ * - Booklet
+ - ``book`` (follow with ``nup(2)`` for actual booklet print)
+ * - Leporello
+ - ``modulo(2) {1 2} modulo(1,half) {1 -1}`` (The first ``modulo`` just adds blank pages to the end.)
+ * - Möbius (with patch)
+ - ``interleave(2)``
+ * - Möbius (known page count)
+ - ``select {1..5 10..6} modulo(1,half) {1,-1}``
+ * - Multiple Möbius bands, odd-even
+ - ``modulo(4) {1 3 2 4}``
+ * - Multiple bands, "modulo 3"
+ - ``modulo(6) {1 4 2 5 3 6}``
+ * - Second half (smaller) of pages in reverse order
+ - ``modulo(1,half) {-1}``
+ * - Second half (smaller) of pages in normal order
+ - ``modulo(1,half) {-1} modulo(1) {-1}``
+ * - First half (bigger) of pages
+ - ``modulo(2) {1 2} modulo(1,half) {1}``
+
+I might create more patches for avoiding the weird ``modulo`` commands…
+
+----
+
+.. [#illustrations] Most of the figures in this article are drawn with a single
+ page per a side of a sheet. I consider putting more pages on a single side
+ of paper to be an implementation detail, because it is not always possible
+ (e.g. with too small font) and sometimes you could put more than two pages
+ on a single side of paper, which leads to the fact that if you put
+ everything on one side of the paper, you can see everything at once and save
+ the other side. Not very useful though… My only exception is the booklet
+ printing below, because that one seems to be rather common.
+
+.. [#ordering] See how this neatly puts the first-past-half page right after
+ the half of the stack? Awesome!
+
+.. [#mistake] Also, if you flip the page around the wrong edge, you can just
+ rotate the rest of the stack and end up with the correct orientation.
+
+.. [#multi-mobius] A slight variation for which I can generate the order
+ with upstream ``paperjam`` is using this order on small subsets of pages.
+ For example, if you only want to be able to see any two consecutive pages,
+ you can do this for just four pages – the order is then 1+3, 2+4, 5+7, 6+8,…
+ Since each sheet either contains two odd or two even pages, the following
+ page is on different sheet than the previous one. And you can do this
+ "modulo 3" to see three pages: 1+4, 2+5, 3+6, 7+10, … This "simulates"
+ multiple smaller Möbius bands, but will be probably harder to use.
