PrintOnBothSides in ppd

[shermin]

Hi,

I added an option "PrintOnBothSides" in PPD for my printer.But that option is not coming in argv[5] of backend.

*OpenUI *PrintOnBothSides/PrintOnBothSides: Boolean
*OrderDependency: 10.0 AnySetup *PrintOnBothSides
*DefaultPrintOnBothSides: 0True
*PrintOnBothSides 0True/Yes: ""
*PrintOnBothSides 1False/No: ""
*CloseUI: *PrintOnBothSides


I did like this.but argv[5] is coming only "PrintOnBothSides".
Why so?
