as in the command line version of installing a printer. The above code installs the printer and sets the default to double sided, but the "Duplex Printing Unit" is still not enabled.

It is the command line version of logging into 127.0.0.1:631/printers and going into "Set Default Options" and "Options Installed" and set "Duplex Printing Unit" to Installed.

- or -

Going into printer setup > driver and check marking the "Duplex Printing Unit".


I want to do this in a script however I do not know how to enable the Duplex Unit.
