Description of problem:
When I set options for my HP2200's Postscript driver like double-sided printing
( appearing twice !! ), click on the OK button and then the Apply button in the
main window nothing seems to change,  indeed. Editing the configuration again,
the values are still the old ones.
Version-Release number of selected component (if applicable):
printconf-gui-0.3.77-1

How reproducible:


Steps to Reproduce:
1. Configure a HP2200 printer ( Postscript driver ) and edit the driver option
'Double-sided printing' to 'Long Edge ( Standard ) 
2. Click OK and then Apply in the main window.
3. Edit again the driver option as above.
    
Actual results:
The option is unchanged indeed and printed pages are flipped.


Expected results:
Options saved from previous configuration and double-sided printing working
correctly

Additional info:
The 'Double-sided printing' option appears twice in the list, with different
possible choices in the menus.
