FAQ

I have added a duplex option to my printer but even though my spool file attributes show that the job should be duplex, it prints in simplex. Why is that?

If you are certain that the printer has a duplexer installed, then the problem might be:

• The interface IPDS configuration does not have duplex enabled

Or, in the case of a Twinax attached device,

• The Advanced Function Printing parameter in the device description is set to *NO and the interface is not set up to emulate a 3816. With the AFP parameter set to *NO, duplex printing is only possible in 3816 emulation. If set to *YES, duplex can be obtained in all of the IPDS emulations.
