## DocumentDuplex class

Describes the duplex characteristics of the output. The duplex feature allows for<br/>            printing on both sides of the media. Each document is duplexed separately.<br/>            DocumentDuplex and JobDuplexAllDocumentsContiguously are mutually exclusive.<br/>            It is up to the driver to determine constraint handling between these keywords.<br/>            https://docs.microsoft.com/en-us/windows/win32/printdocs/documentduplex
