Duplex/tumble mode

The following report of a possible bug in a2ps is submitted.

SHORT:  duplex/tumble flag not being sent to printer

BRIEF DESCRIPTION:  When printing a file to a printer in DUPLEX or TUMBLE 
mode, a2ps appears to be formatting the document correctly, but the printer 
does not print in duplex/tumble.  Printers respond normally when used from 
other applications.  

DETAILS:

The following command is typed at the prompt:

prompt$ a2ps -R --columns=1 --sides='tumble'  -P HP_2499 fname.py 

The response is:

[fname.py (Python): 6 pages on 3 sheets]
request id is Phaser_2499-1072 (1 file(s))
[Total: 6 pages on 3 sheets] sent to the printer `Phaser_2499'
[11 lines wrapped]

The printed output is in single-column portrait mode, but is not duplexed 
(tumbled or notumble).

I have verified that this problem occurs with two separate networked printers 
(one an HP, one a Xerox).  I have also verified that using other applications 
(e.g., kprinter) *will* print in duplex and tumble modes on both of the 
printers.  

Info:
Fedora Core 5
cpu:  Intel(R) Xeon(TM) CPU 3.20GHz    (from /proc/cpuinfo)
kernel:  2.6.17-1.2174_FC5smp              (from uname -a)
GNU a2ps 4.13                                     (from a2ps --version)
cups 1.2.2-1.8                                       (from yum list)


I have been successful using a2ps in times past to do duplex/tumble printing 
to these two printers.  I believe the problem may be unique to Fedora Core 5.

Thank you.
