As reported in Ubuntu at
https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/48694 by Dražen
KaÄar and Till Kamppeter:

OpenOffice.org saves all PPD option settings of the printer(s) in the document
when you save your document after having printed it. And it saves really all
options, not only the ones you have changed. So if you change a default on your
CUPS server afterwards (Installed Options/Duplex Unit: Not Installed ->
Installed) this will not have any influence when you continue working on your
OOo document. You must go onto the "Device" tab of the "Properties" dialog in
OOo and change the  option there, too. 

Proposed fix:

This has to be done upstream, as it is an OpenOffice.org problem and this
appears the same way in every distribution.

The printing dialog of OOo should not display and save any option in the group
"Installed Options" (or "Options Installed") of the PPD file. It should always
take the server default of these options, as these options are set by the system
admin on the CUPS server according to the printer's hardware configuration.

In addition, the dialog should (if possible) keep track which options the user
has actively changed and only save these ones. So changes of the defaults on the
server will be respected.
