Hi ,

one of our client is facing issue while printing from planet press in OKI B731 printer

when using generic(Default) PPD , duplex printing is fine but tray selection is not working.

when using OKI ppd , tray selection is fine but it doesnt print duplex even if choose 2 sided in application .

where as customer is using another Konica minolta printer with its PPD working fine .

OKI PPD details :

*% _____ Duplexer definitions _____
*OpenUI *Duplex/2-Sided Printing: PickOne
*OrderDependency: 95.0 DocumentSetup *Duplex
*DefaultDuplex: DuplexNoTumble
*Duplex None/Off: "
<<
/Duplex false /Tumble false /Policies << /Duplex 2 >>
>> setpagedevice"
*End
*Duplex DuplexNoTumble/Long-Edge binding: "
<<
/Duplex true /Tumble false /Policies << /Duplex 2 >>
>> setpagedevice"
*End
*Duplex DuplexTumble/Short-Edge binding: "
<<
/Duplex true /Tumble true /Policies << /Duplex 2 >>
>> setpagedevice"
*End
*?Duplex: "
currentpagedevice dup /Duplex known{
dup /Duplex get{
/Tumble get{(DuplexTumble)}{(DuplexNoTumble)}ifelse
}{pop (None)}ifelse
}{pop (None)}ifelse = flush"
*End
*CloseUI: *Duplex

Konica minolta PPD :

*OpenUI *KMDuplex/Print Type: PickOne
*OrderDependency: 15 AnySetup *KMDuplex
*DefaultKMDuplex: 2Sided
*KMDuplex 1Sided/1-Sided: "<< /Duplex false >> setpagedevice"
*KMDuplex 2Sided/2-Sided: "<< /Duplex true >> setpagedevice"
*CloseUI: *KMDuplex



what could be the problem in this case.
