PPD file for sample printer that supports duplex

For a printer that supports duplex printing and that is set up with a PPD using the standard "Duplex" PPD option, there are two places where the value for the "Duplex" option can be set and those are not properly synchronized.

Steps to reprooduce:

0) Set up a (dummy) printer that supports duplex printing, e.g. using the attached PPD file:
  sudo lpadmin -p tofile-ricoh -v ipp://printer1.example.org/ipp/print -P tofile-ricoh.ppd -E

1) start Writer
2) open print dialog (Ctrl+P)
3) select the printer set up in step 0
4) observe that "Paper sides" is correctly set to "Print in both sides (long edge)"
5) click on the "Properties" button
6) observe that "Duplex" is set to "Lange Kante" (OK, German translation for "Long edge)"
7) change value for "Duplex" to "Aus" (i.e. "None")
8) click "OK" to close the "Properties" dialog
9) observe the value shown for duplex in the main print dialog

Result:

The value is still "Print in both sides (long edge).

Expected result:

The value should be the same as set in step 7, here "Print only in one side".


Additional notes:
* When printing to an actual printer, the value set in step 7 is used, not the one shown in step 9.
* Synchronization works correctly the other way round, i.e. after changing it in the main print dialog and then opening the "Properties", the previously set value is shown there.
