Printing example, first side

Description of problem:
When I try to print duplex (flip on long edge) on an HP OfficeJet Pro 8500 A909a, page two is mirrored on the Y axis, making the 2nd side unusable. Also, the page is not rotated, making the output head to foot instead of head to head.

Version-Release number of selected component (if applicable):
hplip-3.10.2-2.fc12.x86_64 and ancilliary files.  This also affects the i686 version.

How reproducible:
Update to hplip-3.10.2-2 (yum update hplip* hpijs libsane-hpaio, reset printer driver to pick up new driver and attempt to print duplex.  2nd page mirrored and not rotated

Steps to Reproduce:
1. Update hplip* to 3.10.2-2 along with hpijs and libsane-hpaio
2. reconfigure printer to use newer ppd from installed drivers
3. print a duplex document and select the option to flip on long edge
4. document will have the 2nd page mirrored on Y axis (mirrored left-to-right) and not rotated so that it prints head to foot instead of head to head
5. Downgrade the printer files to 3.9.8-21
6. reconfigure printer to use the proper ppd
7. print a duplex document and select the option to flip on long edge
8. document prints correctly
  
Actual results:
Unusable document with 2nd pages mirrored on Y axis and head to foot

Expected results:
2nd page should print with heads and feet of the pages aligned and readable on both sides.

Additional info:

As stated, this affects both the x86_64 and the i686 versions.  I have tested on both my desktop system (64 bit) and my netbook (i686) with the same results for both.
