This is a problem of evince. Usually, applications (or the application's
print dialogs) do not do the page management (reverse order, N-up,
selected pages, ...) by themselves but instead, they send IPP attributes
to CUPS along with the job and then CUPS does the page management (in
the pdftopdf or the pstops filter). evince does the page management by
itself and therefore this bug is a problem of evince. You can easily see
it by doing the described steps to reproduce this bug, but instead of
clicking on "Print", get a preview by clicking on "Print Preview" and in
the preview the bug appears, too.

Title:
  When printing in reverse, swaps even/odd if # pages is even

Status in “evince” package in Ubuntu:
  Confirmed

Bug description:
  The print engine prints the wrong pages if printing an even/odd subset
  in reverse order, if the total number of pages is even.  I suspect
  that the "reverse" is causing it to first reorder the pages and then
  internally number them, which has the effect of swapping the even/odd
  parity if the total number is even.

  Steps to repro:
  Load into evince a document with an even number of pages (e.g. attached)
  Ctrl-P to print
  Click the "Reverse" checkbox
  Click "Page setup" tab
  From "Only print" pulldown, choose "Even sheets"
  Click Print
  Printer will print pages 3 and 1 in that order.

  Choosing "Odd sheets" will yield pages 4 and 2.  Following the same
  steps with a similar document of three pages will (correctly) get page
  2 for the "Even sheets" and pages 3 and 1 for "Odd sheets".

  This is a problem because the natural way to print double-sided with a
  non-duplex printer is to print the evens in reverse order, then refeed
  the stack and print the odds in the correct order.  (So page 2 is the
  last page printed in the first batch, and its back, page 1, is the
  first page in the second batch.)  Following that algorithm with this
  bug in place gives you all the even sides twice.

  I am on Ubuntu 11.04 Natty.
