problem with printing booklet

[P. Nagaraj,Dept. of HEP,215 2971 x2610,510 0423]

Hello!

I am trying to print on A4 sheets such that they can be folded in the 
middle to make A5 size booklet.  I looked into mail archives and found 
what I needed. But I still have a problem, and am unable to figure it 
out.  I am sorry if I am missing something obvious, but please help me out!

My ~/.a2ps/a2psrc is contains
-----------------------------
# Default Printer, and default options
DefaultPrinter: | lpr -P lj5
Options: --medium=A4
Options: -s2 --setpagedevice=Tumble:true

# A5 size booklet
Printer: booklet | \
#?o! psbook | psnup -2 | pstumble | lpr -Plj5 \
! echo "Cannot be used with more than two pages per sheet." >&2 ; exit 1!

UserOption: booklet -1Pbooklet
----------------------------------



And here is a screen output of a2ps
-----------------------------
address@hidden ~] a2ps -=booklet test.txt
[test.txt (plain): 4 pages on 2 sheets]
[4] [1] [2] [3] Wrote 4 pages, 20524 bytes
[1] [2] Wrote 2 pages, 23494 bytes
[Total: 4 pages on 2 sheets] sent to the printer `booklet'
------------------------------


My problem is: pages 2 & 3 are swapped and upside down.  

I also tried these two commands. With or without pstumble, the outputs 
were identical, that is pages 2 & 3   rotated 180 degrees.
address@hidden ~] psbook ~/test.ps | psnup -2 | pstumble | lpr
address@hidden ~] psbook ~/test.ps | psnup -2 | lpr

I tried sending the outputs into a file instead of lpr and checked with 
gv - there was no upside down page displayed. Only the hard copy has the 
problem. 

Thanks for helping me out!
