## Discussion

Discussion Duplex printing is a print job that prints on both sides of the paper. Two-Sided printing controls are displayed in the Layout pane of the Print dialog. This function allows you to specify whether the document should be printed single-sided, double-sided with short-edge binding, or double-sided with long-edge binding.   note: Not all printers support duplex printing. This function specifies a setting that might not be available on a given destination. If you call this function after initiating a print job, the change is ignored for the current job.
