[Pkg-cups-devel] Bug#501311: cups-client: -P and -o number-up=2 interact surprisingly

[Sanjoy Mahajan]

Package: cups-client
Version: 1.3.8-1lenny1
Severity: normal
File: /usr/bin/lp

This command did 2up printing of pp. 81-102 from file.pdf:

  lp -P 41-51 -o number-up=2 file.pdf

I expected it to extract pp. 41-51 from file.pdf, then convert them to
2up and send it to the printer.  

I can think of two fixes:

1. In the description of the -P switch in the 'lp' manpage, explain
   that the page numbers are those after page rearrangements.

2. Change the cups filters to first select pages with -P, then
   rearrange pages.

The first fix clarifies the situation but makes it hard to use -P
with number-up, so I like the second fix.
