According to Mike Sweet [1]:

"Dec 28, 2007 by Michael Sweet:
The 1.1.x (and 1.0.x) behavior was incorrect. According to the IPP specification, number-up is applied *first*, and page-ranges refers to the imposed pages. Similarly, page-set is applied after imposition."

and here [2]:

"Nov 16, 2008 by Michael Sweet:
IPP specifies the page-ranges applies after imposition, so the current implementation is correct.

I'll add a note to the documentation about the behavior."

My man page of lp(1) says:

"       -P page-list
            Specifies  which  pages  to print in the document. The list can contain a list of numbers and ranges (#-#) separated by commas (e.g.
            1,3-5,16). The page numbers refer to the output pages and not the document's original pages - options like  "number-up"  can  affect
            the numbering of the pages."

And -P is just a shortcut for page-ranges=.

For that reason pstops handles page-ranges the way it does. And pdftopdf
deliberately follows pstops' logic.

However I don't know which IPP specification Mike references here. From
my understanding of RFC2911 (IPP 1.1), Section 15.3 [3], page-ranges is
applied in step 2, and number-up is applied only in the next step 3.
Maybe Mike can shed some light on this issue?

Title:
  Number up option is processed before the page extraction option

Status in cups-filters package in Ubuntu:
  New

Bug description:
  When printing multiple pages per sheet, it seems that number-up option
  is processed before the page range option.

  For example, the command below will print 4 pages of the document
  using two sheets of paper, instead of one sheet with two pages.

  lp -o page-ranges=1-2 -o number-up=2 filename.pdf

  This bug makes it impossible to print odd number of pages with number-
  up option > 1. Say, if I want to print three pages using two pages per
  sheet, and I will not be able to.

  This was tested with Cups 1.7.5, cups-filters 1.0.69 on Ubuntu.
